I have a record player that the idler wheel slips causing the speed to be slow so i was wondering how to correct that? thanks.

You can replace the idler - for that you need to know the make or better the idler code.

You can also have it rebuilt. You send the idler to a place to have the rubber replaced with fresh pliable rubber that is the correct size. The place many swear by is Terry's. There are others too.

YOU CAN TURN IT ON A LATHE TO GET A NEW SURFACE, USE A CONTRAROTATING GRINDER. (THE DIAMETER IS OF NO CONSEQUENCE AS LONG AS IT IS ONLY ONE DIAMETER)

If the wheel isn't hard and dry you can clean all of the drive surfaces including the motor shaft, idler wheel and the inner turntable rim with a non-oily solvent like naphtha or denatured alcohol to remove any oils or grease and dirt causing the idler to slip.

Sometimes a slipping idler wheel is only part of the problem. The motor bushings may also need cleaning and lubricating as well as the platter thrust bearing.

Thanks I cleaned the shafts and put a light lubricant on them and I also cleaned the idler wheel with alcohl. When I holt the turn table I can hear the motor spin slightly still.

I'm working on a Webcor, I needed to have old wheel rebuilt..
I used a recommended vendor (as the forum said)

http://www.vintagelectronics.com/

He did nice work for me, and I bought a new cartridge as well

I cleaned the idler wheel again and now when i hold the turntable the motor stops. I am thinking the motor is weak because it plays 45's at a slower speed. I dealt with West Tech in the past maybe I can send him the motor to see if he has one like it.

Now you've got it. That's the sign of clean drive surfaces. The reason you are still slow is most likely gummed up lubricant in the motor bushings. There is only one lubricant that will work in this application and that is turbine oil or paraffin oil. It comes in a plastic bottle with a zoom spout oiler and is available at most hardware stores. This oil will not burn and thicken with the high temperatures developed in the bronze bushings of the motor.

It's best to disassemble the motor first, flush the bushings with solvent then apply fresh oil. The bushings must be re-aligned when the motor is re assembled so they do not bind, slowing the motor.

The shaft of the idler wheel also must be cleaned and lightly oiled. The turntable bushing and thrust bearing should be cleaned and re-packed with lithium grease. Once all of these items have been performed you should be running smooth, quiet and right on speed.

I was looking at the motor and there is no screws to take the motor apart and the bottom of the moter is sealed

Does Terry's do phonograph repair and does he have a web site or phone number? I am not happy where i sent it to be fixed.

The motor repair is not hard to do really, and Doug laid out the process. I have done this a few times for Garrard and Dual motors. What you are describing sounds like this. It can be kind of a pain to take it all down, especially when the solution is a quick couple of drops of oil. But your motor should have some way to open it. There are some that will require use of a snap-ring pliers to open. You have to pry them open to pop them. Can you get a pic of it posted?

I'd recommend Ed Crockett at the vintagelectronics.com address.

Turnaround time is quick and the quality of work excellent.

I removed the motor and drilled a tiny hole on the bottom where the shaft would be and put a little oil on each ends of the shaft and it spinns better but still a little slow.

Wouldn't changing the diameter change the platter speed?

IDLERS, AS LONG AS THEY ARE ONE WHEEL ON ONE SHAFT WILL NOT EFFECT THE SPEED. THATS WHY THEY ARE REFERRED TO AS "IDLERS".

Ran across this thread because I sold an old GE 78 Record Player to a new Member here.
I noticed the Idler Rubber was hard . Started looking for replacement . WOW !!!! $20-$30 + shipping

I put the original one , which measured 2 " Dia in lathe. Removed old rubber.
Install "O" Ring from my stash, Luck I guess 2.010 inches dia. Nice tight fit

Whew got lucky once again.

The new owner will sure be happy.
