Failed Pinion Bearing Install: Science experiment failed!

[@Headsup9550]

You didn't freeze the pinion long enough, it stayed out of the freezer too long, and you need to have your pinion shim on it. You could have run it down quickly with a air chisel as long as you stay on the inner race with it. The best thing I ever did was buy a kit off Amazon for pressing/removing bearings on differential stuff. It's also worth mentioning that when you're setting up a diff, I always buy a spare inner pinion bearing and machine the inside of it so that it'll slide on and off while finding the perfect pinion shim. Once you figure that out, you press the unmachined bearing on it and assemble it all.. I have a drawer in my toolbox that has machined bearings for all the popular rear ends so that I only have to machine the bearing once per type of year end, then I can keep it for the next one that I do. I happen to do a lot of ring and pinion swaps though so you may not find that part especially handy. At some point you'll get to the point where you do ring and pinion swaps more often and it'll come in handy..

It works but you need to freeze the pinion gear overnight

Is the new channel name "Cookin with Taters"?

[@robertmoore9346]

we always submerge the bearing in oil to heat it and leave it at 350 degrees for 30 mins and put the pinion in the freezer overnight.

I just chuck my pinions into the drill press, polish the black coating off then heat the bearing with my hand torch till its hot to touch and it pretty much falls on. Never tried the freeze n heat method

[@pdh098]

Just heated with a torch for a couple minutes, I have done it many times. Evan wouldn’t get it out of enough. Pressing it on works just fine to.

[@houstonpeyton]

Stuck now though ain’t it? Don’t believe heating will help me now 😂

[@funfun8095]

​@@houstonpeytonYou can get a bearing separator at hazard fraud and pull that back off, with a press. Don't mess around with the light weight press, at HF, just get the heavier 20ton. I finally got the big boy, years ago and it's night and day, from the cheap one.

[@killercoyote1905]

What about your pinion depth shim? It has to be measured and go on first before pressing bearing on

[@houstonpeyton]

@@killercoyote1905 looks like i forgot something else… woohoo

[@Smokey72013]

I just use a heat gun on the I'd of the bearing. Then use a piece of pipe to seat it fully. Totally possible tho. Hopefully you are already know your setup shims if necessary. Lube does help but heat is your friend. Trust me on a heat gun or a propane torch carefully only if the spacer is metal and don't change the color of the balls or your screwed

[@garymatthys3605]

where's your shim?

[@houstonpeyton]

@@garymatthys3605 something else i forgot
