throwout bearing side to side play

Postby pett3227b » Mon Apr 04, 2022 12:37 pm

I have inspected the carriage that the throwout bearing rides on and I have about a half inch of side to side play where the carriage rides on the rod that goes through the bell housing. Should the bearing- bushing be in there tight or is it meant to move side to side on the rod? Thank-you

Hi,
Look at the wear pattern on the throwout bearing, it should look even, like the bearing was centered on the 3 pressure plate fingers.
The pattern might look bad, from moving side to side. If the throwout bearing looks bad, it should be replaced.
A picture would be helpful.

You can bend the upper part of the throwout bearing holder out, so both sides are almost touching the clutch housing, but don't bent it down too low, the throwout bearing has to be squeezed by the holder, so it stays upright.
If the holder doesn't squeeze the bearing enough, the bearing can flop down and rub on the fingers.

If you don't want to bend it, you could use some small washers, and put on the top pin, in the right places, to fill the gaps on both sides. The holder has to be free moving forward and back.

Check the holes in the holder, sometimes they are worn, then the holder needs replacing.
The top pin can wear, then it needs replacing too.
TM Tractor has a new holder and top pin.
Their holder is for Cubs with the external clutch pedal free play adjustment, Cub serial number 32229 and above.

When ready to put the Cub together, you could join the halves together, put in some of the bolts that hold the halves together, and look in through the hand hole under the clutch, with a light, and check where the throwout bearing contacts the fingers, to be sure the bearing is centered.
If it is offside too much, split the Cub again, and move the holder to the right position to center the bearing on the fingers. My opinion. :)

Yeah I might just bend the yoke back into shape. Is the left side a mirror image of the right side? looks as though one side is bent and the other is strait. I could just put them together and make sure they are equal. I have either a 47 or a 48 farmall cub and was unable to find a yoke for these years. Does anyone know where I might buy one? Thank-you

Hi,
Below are pics from TM Tractor of the 1st style throwout bearing holder.
It looks like both sides are straight. :)

TMTractor may have a used one. Or you could try JPTractor salvage in Fredericktown, Missouri
