Should sealer be used on the shims that adjust the gear lash between the steering worm gear and the gear in the power steering unit? This happens to be on a 520. Mine is leaking around the shim. I used an old shim, but will replace with a new one(s).

Sealer will add to the thickness of the shim.

The paper shims, yes? They used to have thick and thin ones, now only the thin ones are available. I use a VERY thin coating of Permatex Aviation on all shims. Just enough to seal them all together. Then a very thin coating on each housing.

Thank you. Both thicknesses are still available from Deere. I ordered
them today. I am not sure if they are paper or the harder material.

I took it to mean the shims between the worm and the spindle gear to set backlash. Only paper shims there...
Now, for worm bearing pre-load or freeplay, then that cap has an o-ring.
Yes the sealer on the shims add a little thickness. I figure that in. Better than a leak later.

Thanks. It is the paper shim that is leaking, not the cap.

Gee willikers, think about it. Did the 'source' of the product use 'sealer'. Give your head a "SHAKE". --more than one -yipes.

And then they are all garbage the next time they are removed.
They were not sealed together from the factory. There's your
sign.

Kent,

I appreciate your trying to give me a straight answer. I have the manual and have studied the parts diagram. I do not see how the O-ring keeps the oil from getting to the shims. It seems like to me that the oil could come from both sides of the shims. I am talking about the shims between the steering worm housing and the pedestal.
