Questions & Answers
Can this part be used with a sealed front bearing?
Willys Jeep Parts Tech:
Yes, it doesnt effect it.
Yes, it doesnt effect it.
The oil passage on one I received is partially blocked with casting material. Is this intended to reduce volume of oil flow through bearing to help reduce leakage or should I grind out this extra casting material to open up passage to full width?
Willys Jeep Parts Tech:
Casting. I would clear it and if you need a replacement we are happy to help on too.

I installed this bearing retainer and now my throwout bearing and fork catch on the hole in the bell housing and my clutch is completely unadjustable and won’t release. What am i missing, does this require a different clutch fork?
Willys Jeep Parts Tech:
Your clutch release cable is adjustable and your free pedal travel should be checked.

If I tighten the 3 bolts on the bearing retainer my transmission gets tight and I cannot turn the yoke. Is there a shim that needs to be added ?
Willys Jeep Parts Tech:
No shim at the front bearing cap. Your new grease seal is most likely just tight in the front. They are hard to turn by hand when new.

How come you don’t have clutch releases pin on the other side for left hand clutch and if you do is it a different part number
Willys Jeep Parts Tech:
You can use this as a LH drive too. You just need to move the fulcrum.

I have a 59 Willys with a T90 transmission the number stamped in my retainer is 3741458. Is this the same retainer?

Says it comes with new neoprene seal. Does this stop the oil from traveling into the bell housing, because the felt seal don't stop it and now my clutch is oil soaked and slipping. I've heard I can get a sealed bearing and replace the front bearing with it, but if this new cap and seal stops the problem, I wouldn't need to pull the shaft and bearing.
Willys Jeep Parts Tech:
this prevents any transmission fluid from leaking into your bell housing that is correct.

Willys Jeep Parts Tech:
This bolts to the outside of the transmission case. It slides over the input shaft.

Two questions: 1. How much play should the main drive gear shaft have in this bearing retainer cap? Mine is not snug. 2. Is there a way to remove and replace the front bearing (mine has a little play in it) without removing the entire main drive gear shaft from the tranny?
Willys Jeep Parts Tech:
You should snug. There should be approx. .003" on end play. Sorry, you will have to dissemble the transmission to replace the front bearing.
