Hi guys,
my 4.10 R&P's from gbr finally came in. Im in the precess of intalling them but i cant get the pinion bearing off of my standard pinion to put it on the new one. Does anyone have any advice as to how to pull this off? Should i just buy a new one? who could get it to me this week? Its in great shape and I would rather not buy new ones if i dont have to.

thank
-Rick

you'll send as much on a puller than a new set of bearings.

with that said, if you want to reuse the bearing, take the 3.54 pinion to a machine shop and have them swap the bearing on to the 4.11 pinion.

a word of caution....once the large pinion bearing looses it's preload, they have more of a tendency to make noise once reloaded. this isn't a general rule type of deal, but in my experience used pinioin bearings get noisier faster.

if your using a used bearing set, your preload numbers will also be smaller, as the bearings are already run-in.

if reinstalled with used bearings the preload setting will be closer 18-20 inch pounds as opposed to 20-25 inch pounds. when setting the preload, do so with out the seal installed first, torque end nut (Bill supplies a set-up nut) and smack the carrier housing with a brass hammer a few times to help the bearings seat. you'll be amazed how much this will loosen the pre-load up.

good luck,
email me if you have any questions.

Well if you indeed wanna reuse old ones - easiest way to get bearings off the pinion is to use rubber mallet (wont damage things) and keep beating on pinion (not on bearing) till stupid things falls out :) Can use 3rd member or vices to put bearing edges on.

However it is common practice to use new ones. Dont be cheap on that stuff, as it pain in arse to get them out and reset later again and again..

Don't bother with a puller. Get some new bearings from Bill and do it right the first time. I know everybody want's new tools but buy a puller when you want to replace bearings not reuse them. You'll probably f up the bearing your first time anyway.

Steve - how the heck you can f-up bearing? Its not like you can put it on wrong, or can bend it or break some thread... :) I am just curious.

Reusing old pinion bearings on expensive Gears , nice , real nice.. Sergay , shutup... if you dont understand what Steve is saying you probably dont have much knowledge on this subject. Well , outside of beating it...

actually, I am curious, too.
Any part of the bearing, except for the cage, is much harder than a regular mallet. I don't know if a race can be bent out of shape - I'd think it would crack.

this is not to support the idea of reusing the bearing, however. I'd ask Bill to press a new one on if I ordered R&P from him.

What Kyle ? doesn't everyone that spends $1600 on 4:11's save the $30 on bearings...

Half that, and I was hoping to use my truck this weekend. Plus the bearing appears to be in great shape. Sure if i did it again i would ask him to press on a new bearin, just like i did when i ordered my Locker, but i didnt, cuz I forgot.

And i cnat get my RAVE cd to work cuz my cd-rom drive is broke. So does anyone mind looking up every torque spec of every nut and bolt?
thanks

Kyle - what is it with you and eye poking? There was question, and i answered. I didnt suggest to reuse old ones but hey - if he want to do it - its his right. I am merely interested in Steve's opinion or anyone elses who actually has opinion (as oppose to tell someone to shut up, curl up and die, be quiet & etc) , thats all. If you has deep knowledge of subject and can explain - please do tell.
I am not trying to be anal here, i am just trying to get better idea on "why" and only way is to ask questions. I thought that was purpose of site - to share information.

Steve - well i sppse you can damage cage, but then one have to be careless enough to use it as anchor point..

Peter M. - Teeheee.. Slishkom mnogo ingernogo obrazovania meshaet, ne pravda li.. :)

Ron - nope :) its copyrighted. Plus there is indeed possibility to damage it while pressing on or off , if cage is used as pulling/pushing point.

Bruno - it actually will be at least about 170$ on bearings (2x2, and they are of different size for inner and outer).

Sergay. What is up is that I mind when people who dont know much about a subject pop up and start giving advice. YOu have to use a fixture that clamps the inner race to get it off. Most times its too thick to fit under the race correctly and it will pop off once or twice and get the cage before you move the bearing enough to get a good bite. Doesnt happen all the time but it does happen.. How do I know this ? When you do new bearings in a rear you have to ge the old ones off so you have to deal with it. Some people still beat them on and off. I have done it as well but it just opens doors for error. Youarent dealing with tractor parts here and your margin of error is very small. You will have to live with your screw up for miles and miles. If you flat out dont give a shit about noise and precision then by all means , beat the living shit out of it , I can respect that.. But dont advise someone that just might give a shit to do the same. How thats not eye poking is it ? Just telling you how it is without going in depth and typing a novel... Have a nice day

Thanks Kyle.

I tried to write reply yesterday but stupid connection went down again :(

Anyway - so you concerned about cage as well then. Reason behind my question was - when i was putting my new gears in, i used new bearings so old ones been free to play with. So i figured that i may as well try to break them to see how it all works - and it took some effort to actually break outer bearing (i didnt feel like repeating it on inner) - with hammer and chisel :) So i was wondering what i missed b/c it was only point i found where it actually breaks (well apart from trying to pull one of them small cylinders from inside the cage, but it seems to be somewhat unnatural for usual breakage).

Let me emphasize this again - i am by all means not recommending to reuse bearings (goes for all of them actually, not only to ones on pinion), new ones will always bee good idea. However is someone feels like going route of reusing - well. Its life :)

pinion height set-up race

on the plus side to getting new bearings,
now you can use your old race as a set-up race to get the pinion height right.
take the old race to a belt sander or the like and sand a bit off the outer egde.
now the race will drop into the housing without having to press in and out. once the pinion height is right simply swap with the new race.
keep in mind that the pinion height shim on the new gear set will differ from what was used on the 3.54 set.

good luck....
