Lawn Mower Wheels – Fix The Axle On Height Adjusters

On push mowers with the spring loaded height adjusters the attached axle usually needs to be replaced annually due to the metal shaft wearing down. It usually starts with a slight wobble of the rear wheels and then turns into an outright lean of the wheels as the wheel mounting hole and the shaft wear down. Replacing the wheel by itself will help for a while but it won't make it perfectly aligned because the axle has been worn down also and needs replacing.

Replacing the worn axle is easier than it sounds. First you need to remove the wheels, height adjuster and axle assembly from the mower. You will notice that the original axle has been stamped on to the height adjuster so it will need to be hacksawed off. Once you have sawed off the old axle then punch the remaining piece of old axle out of the height adjuster. Once the old piece has been removed there will be a 3/8 hole, most of the time. Sometimes the hole is a little smaller so you will need to drill it out to 3/8". Then get a 3/8" bolt long enough to go through the new wheel, two washers, and the height adjuster and leave approximately a half inch of thread showing for the retaining nut. You will need a piece of 3/8" ID and 1/2" OD piece of tubing to use as axle sleeves. Cut the tubing approximately 1/16" wider than the wheel mounting hole so when you tighten the retaining nut the wheel will turn freely. Lightly grease the 3/8" bolt before you put the tubing and wheel over it, tighten the retaining nut and you should be good for another year.
This fix should only cost about five dollars as opposed to replacing the height adjusters at a cost of fifteen dollars each and the parts can be bought at most home improvement or hardware stores.

Toyota OBDII (CEL) Codes

If you have a problem with your Toyota Matrix where the check engine light comes on and goes off look for one of the evaporator system trouble codes to be set. I have had that happen to me three times so far this year and it turned out to be caused by the gas cap, but it is a good idea to have the OBD II codes just in case it is more than that. Sometimes on the Matrix, the evaporator system hoses can leak setting an engine code. If you suspect a leak in your evaporator system be sure to check the hoses on the canister above the rear axle.

Here are the Toyota OBDII (CEL) codes for those that need it.

Troy Built Lawn Mower

My two year old Troy Built, self-propelled Tuf-Cut 210 had a front wheel that started wobbling badly. Since I really don't use the mower much I didn't know why the wheel should have gone bad so soon. I removed the wheel and noticed that the inner metal bushing had frozen itself to the axle shaft and began to spin inside of the plastic wheel causing the inside of the axle hole to wear out completely. The wheel went bad on the left front of the mower. The wheel on the right front of the mower seemed ok until I took it off and noticed that it too was just beginning to spin on the inner shaft but it had not really done much damage to the inside of the wheel yet.

I took both wheels off and freed up both inner bushings and removed them. The axle itself seems to be in pretty good shape so I will be able to re-use it this time. In the future I will have to be more diligent about checking the lubricant on the axle shafts and re-lube them periodically. My old mower is a strictly push type with plastic wheels that never needed and lube so I just assumed that this Troy Built was the same. But is isn't so be sure to keep the wheels rolling freely in front so they don't chew the center out of the wheels.

Toyota Corolla With Poor Gas Mileage

I have a 1995 Toyota Corolla that normally averages 38 miles per gallon. I usually keep track of the mileage at each fill-up and noticed the mileage dropping slightly every week. I really didn't think anything of it at first I thought it could be the weather or possibly the gas itself.

It didn't seem to matter, the mileage kept decreasing until the car was getting only 30 miles per gallon. I knew something must be wrong so I took it in to the Toyota dealership to have them check it out. They found nothing wrong with the car at all, either with the electronic system or mechanically. The car only has 80,000 miles on it so I figured that it couldn't be wear causing any problems not yet at least. When I was in the car business it was not uncommon to see a Toyota Corolla with 200,000 miles on it and still running strong.

During closer observation of the engine I noticed that it idled fast as though it was cold even after having been driven for several miles and the temperature gauge in the normal range. In the same conditions a few miles down the road the idle was normal then after that it went to fast idle again. After looking in the shop manual for the 1995 Corolla, I went to the dealer again and asked them what it could be and they said that they have never heard of that happening. I decided to investigate the problem myself to avoid expensive diagnostic costs. I checked a maintenance manual for the car and found that there was an (IAC) idle air control valve that let air bypass the throttle body when the engine was cold to allow for a faster warm-up idle. Once the engine was up to temperature the valve would close and the idle would return to normal. I checked and changed the easy things first, PCV Valve, air cleaner, etc. but no luck.

I decided that I was going to have to remove the Idle Air Control valve and check it to see if it was working the way it is supposed to. I really was trying to avoid removing the idle air control valve because it required draining some anti-freeze. The idle air control valve is directly below the throttle body and has coolant lines running through its housing to provide water from the cooling system to the thermally activated motor that turns the Idle Air Control Valve on and off. I did the work on the engine when it was cold so not too much water leaked out. When I got to the valve shaft I noticed some corrosion on it and cleaned that off, other than the corrosion the idle air control valve looked to be in good shape.

After putting the IAC valve back together I drove the car to see if there was any change and there was not. It still idled erratically. As the engine was warming up, however, I noticed that the temperature gauge went way down when the thermostat opened up them gradually returned to its normal range. That seemed odd so I got a temperature probe and dipped it into the coolant to see exactly where it was and found that it was approximately ten degrees cooler than it should have been. At that point I just let the engine idle for fifteen minutes and the idle went to normal and the coolant temperature went to its operating range. That fluctuation in temperature told me that the problem was the thermostat. I replaced the thermostat with a genuine Toyota part even though it is more expensive it is worth the money because it is exactly like the old one and the gasket pattern is the same. The after-market thermostat , from a local auto parts store, was made to fit many types of cars so to make it work for my Corolla would mean that I would have to drill a small hole in the edges of the new thermostat for bypass where the OEM thermostat needed no modifications to work properly.

Lawn Mower – Briggs Stratton Engine Won’t Stay Running

Had a problem with my two tear old lawn mower where it wouldn't stay running. I was just mowing the lawn and it abruptly stopped. There was plenty of gas in it and everything else looked OK, I just couldn't figure out why it stopped.

After checking the spark plug and oil, all of the easy stuff, I took the air cleaner off to look inside of the carburetor, in the carburetor throat there was a coating of black dust that didn't look like it was supposed to be there. I would have thought that the air cleaner would have stopped the dust from getting through, but instead there it was. I checked the air cleaner itself closely and found an area where the air was getting by the filter and right into the engine.

I decided then to take the carburetor off and clean the dirt out of it. I flushed it out with carburetor cleaner until everything that I could see inside came clean and free of dirt. Then I checked the float and fuel feed to make sure the engine had adequate flow of fuel, which it did. I then re-assembled the carburetor and tried to start the engine. After a couple of pulls it started right up and ran great while I finished the lawn.

Afterwards I went to the lawn mower shop and got a new air cleaner to replace the old damaged one.

Air Conditioning Ductwork – It Pays To Clean It

During this hot summer that we are having here in Florida, I thought my air conditioner was unable to handle the load.  Even though it seemed to be working right and the compressor had plenty of freon it just seemed to run forever to just keep the house at eighty degrees.  I had called a couple of air conditioner companies to check the unit out and make sure it was operating right and they both said that everything was ok.  The last technician told me that I may want to have my ductwork professionally cleaned since the house was over thirty years old.  We had only bought the house three years ago and there was no history for the air conditioning service.

We decided to take his advice and have the ductwork cleaned.  The duct cleaning company came equipped with a large vacuum cleaner and an air compressor to do the job. What they did was start at the furthest end of the house away from the blower and put the compressed air lines in there along with a device that went down the ductwork blowing the dirt out of all of the nooks and crannies.  On the other end, where the blower normally is, they put the vacuum cleaner to collect the dirt as it was blown through.  When they started I couldn't believe all of the dirt and dust that had been sitting up there.  It was a steady flow of dirt from one end of the ductwork to the other.

They did a real thorough job and when they had finished  I noticed a definite difference in both the air flow and temperature.  Now the house gets cooler much faster without the air conditioner having to work so hard and long to bring the temperature down.  I'll make another post when I get my next electric bill, but I bet it will be a big improvement.

Faucet Leak – Fixing A Slow Drip

There are several types of faucets, some are single lever, and others have both hot and cold knobs.

If you have a faucet leak it is necessary to know if you have a washer and seat type or a cartridge type. A washer and seat type of faucet is designed to have the washer attached to the part of the faucet that moves when you turn the handle either open or closed. As you turn the handle the washer either gets farther away from the seat, when you open the faucet, or closer to the seat as you close the faucet.

If you have a faucet that drips after you have shut it off, even after you try to tighten it, you may have a bad washer. Before you do anything you need to go to a hardware store and get an assortment of washers and brass screws so you don't have to take the faucet apart twice. Since the washers are cheap it will be a time saver to just get a few extras.

Once you have the washers turn off the water supply to the faucet and remove the faucet handle. Then remove the large nut right below the faucet handle and unscrew the stem (the part that the handle attaches to). With the stem removed you will find the washer attached to the bottom of the stem. Unscrew the brass screw that is holding the washer and remove the old washer. Match-up the old washer and screw with a new one and install the new washer and screw.

With the new washer and screw installed you now need to check the seat that the washer makes contact with in the faucet. Look down into the faucet with a flashlight and check to see if the seat is intact all the way around it. Depending on how long it was dripping it may have worn a groove in the metal. If the seat looks smooth then just replace the stem with the new washer and the leak should be fixed. If you noticed that the seat has a groove worn into it you will need to touch-up the seat with a tool designed to do that. The seat tool can be found at a hardware store. How the seat tool works is you hold it up against the worn seat and grind the high edges of the seat down to meet the height of the worn part of the seat. After you are finished grinding the seat it should be flush all the way around so when the washer comes in contact with it the water flow will be completely stopped.

The seat grinding tool is not very expensive and it is easy to use. You just turn it by hand, it is not a power tool.

Cloudy Swimming Pool Water May Not Be Yellow Algae

Last spring I had a problem with my swimming pool that stumped both my pool supply company and myself. It was during early Florida spring when all of that yellow dust or pollen is in the air. My pool began to get cloudier and cloudier and the filter could not seem to keep up with clearing the water.
Usually during this time of the year the sand filter had no trouble keeping up with the pollen. It just needed to be back-flushed more often.

This year it was different. As the days went by I was no longer able to see the bottom of the pool and it wasn’t getting any better. At that time I figured that I better take a water sample down to the pool chemical supplier and have them test it. When I tested it always came back with readings indicating that all of the chemicals were in their ideal range. The pool chemical supplier said that the water looked ok and that my problem is most likely yellow or mustard algae. I bought chemicals to treat the algae which required that the filter be running for twenty-four hours to be effective. When I checked the water the next day it was even worse yet. I went back to the pool chemical company and they told me that the process would work it just took time, but that I should start seeing results.

After not seeing results I went to a different pool supply company and the people there knew what the problem was right away just by looking at the water sample that I had brought in. They said that it was the filter. The sand in the filter had become ineffective so I changed the sand and ran the filter for another twenty-four hours and it cleared right up. It turned out that the sand in a sand filter can lose its edges over a few years of being in a filter so the contaminants just pass right through it and back into the pool.

It definitely would have benefited me to get a second opinion before I took any action on trying to fix the cloudy water problem. The cost of running the filter all of those extra hours and the algae chemical were unnecessary expenses.

Changing the sand in a pool filter is routine maintenance that should be done every two years. To keep it running at it’s peak performance.

There are some opinions about a cartridge filter being better that a sand filter. The reasons that I have heard include, they don’t waste water in a back-flush, and there is little or no maintenance at all with a cartridge filter.

My experience with a cartridge filter, since I was talked into replacing my sand filter with one, has been just the opposite. A cartridge filter needs a lot more cleaning than I was led to believe and it takes a lot longer and uses a lot more water. The only difference is that the water doesn’t come from the pool. How you flush out a cartridge filter is was it off with a garden hose. So if you have a relatively large filter cartridge you can be washing your filter for at least a half-hour. The old sand filter took only five minutes to back-flush and most of that time was spent rolling and unrolling the drain hose.

Conclusion: I will be switching back to a sand filter this year.

1995 Ford Taurus Heater Fan Out Of Control

A problem with my 1995 Ford Taurus LX wagon caused the blower motor to operate at high speed with no way to slow it down. It just happened one day when i went to drive the car that the climate control fan ran out of control. The day before it had been fine so there was no warning when it decided to go haywire. The car has an electronic climate control system that regulates the fan speed electronically when you roll a wheel in the direction of either fast or slow.

I checked the climate control assembly by swapping it with another one that I had and there was no change. Checking further into the schematic I noticed that there was a variable blower control, (Ford part number: E9DZ-19E624-A), mounted in the ductwork to feed the temperature and motor speed back to the climate controller. Together they formed a feedback loop.

I removed the variable blower control from the ductwork and noticed that there was a damaged part of the circuit board rendering it inoperable. Since the variable blower control is a dealer item I had to order it from the dealer. I checked several aftermarket auto parts stores and none of them had a part like that so the dealer was the only option. It turned out that the dealer had one nearby at one of their other dealerships so I was able to have the part in a few hours. When I got it and put it in the blower worked fine. So it turned out to be a simple problem requiring a one hundred and twenty dollar part to fix.

Toilet Leak – Fix A Leak Coming From Under The Toilet

Most toilets are constructed to have two joints where a leak may occur during a flush. After a toilet talk fills the only thing preventing the water from flowing out is a rubber flapper covering the water exit in the bottom of the toilet tank. The water is released when the flush lever is pressed. Once the flush lever is pressed the water begins to flow out of the tank and into the bowl where it washes away whatever is in the bowl at the time. As the water is flowing out of the tank it passes a gasket between the toilet tank and the toilet bowl, and then it passed the wax gasket that is between the toilet bowl and the drain pipe. Water rushing past either of these gaskets can leak out if the gaskets have deteriorated enough to create a seem for the water escape through.

Sometimes the wax gasket under the toilet can develop a leak, especially if the floor that the toilet is sitting on isn't completely flat. If the floor has any give to it the toilet will move and eventually separate itself from the wax gasket. When that happens the only fix is to replace the wax gasket. To do that you will need to shut off the incoming water to the toilet and drain it completely. Once the tank is completely drained you can remove the tank with the two bolts under neath the tank. They will be the two bolts holding the toilet tank to the toilet. Remove the water supply line and the two bolts and remove the tank from the toilet. Once the tank is removed you will need to loosen the bolts on the bottom of the toilet bowl. Once the bolts are loose you can lift the toilet off of the floor and lay it on it's side so you can see the wax gasket. The wax gasket will be surrounding the outlet on the bottom of the toilet. There may also be some wax gasket stuck to the pipe flange that the toilet was bolted to. Use a narrow putty knife to scrape off the old wax gasket from both the bottom of the toilet and the pipe flange to prepare the surface for the new gasket.

When you unwrap the new wax gasket it will be sticky and will want to stick to anything it touches. You should hold it with the wax paper that it came in or get a piece of wax paper to hold the gasket with. Stick the new gasket to the bottom of the toilet where the old gasket came from and make sure it sticks and seals all the way around. Prepare the bolts on the flange where the toilet will attach and make sure they are straight and stay up straight as you slide the toilet down over them. It is important that you make sure the bolts will stay up as you put the toilet down because you don't want any interference when you are attaching the toilet to the floor. If you make contact with the new gasket and the flange you don't want to have to lift the toilet up again because that will ruin the new gasket. Wax gaskets are made to make contact once and stay in position to form a tight seal.

As you tighten the bolts that hold the toilet down do so gently as they are not meant to be made really tight. You may need to sit on the toilet to make sure the wax gasket compresses fully so the toilet doesn't move as it is being used or when water enters the tank. The toilet has to be flush with the floor then tighten the bolts just snug to keep it there. Once the toilet has been installed you can replace the toilet tank. You will notice a gasket between the toilet tank and the toilet bowl. If you haven't had a leak there just re-use the old gasket as it has formed to the toilet and the tank already. I was trying to be too much of a perfectionist once and replaced all of the gaskets, to be on the safe side, only to have the gasket between the tank and bowl leak. I replaced the new gasket with the old one and the leak stopped. The porcelain tan, on the toilet that I was working on wasn't formed square so the original gasket formed itself around the irregularities and created a tight seal. The new gasket was too hard to conform to the irregularities of the tank material.

To insure against the possibility of the toilet tank bolts leaking from the inside which would require you to remove them again to fix the leak, put some putty on the inside washers before you re-install the tank. The putty will fill in any void and help prevent any leaks.

Re-attach the water line and fill the tank checking for leaks as it fills. Once it fills flush a couple of times to check for leaks, if you don't find any leaks you are done.
