HELP PLEASE

Was putting my new 14 Bolt Pinion (Yukon Gear) in the carrier. Inside bearing went on zero issues. Crush sleeve eliminator installed.

Was on my third attempt at setting Backlash and was pressing Pinion out of carrier to add more shim.

The pinion came out easy each previous attempt easy peasy

This time IT WON'T BUDGE. Full 12tons of pressing and it won't move. There is nothing keeping pinion from dropping out of carrier. I have an easy 3" of drop room. I used MAP Gas and got the outside bearing good and hot.... Won't budge. Let it soak overnight with penetrating oil... Won't budge. Swapped out for a NEW 12ton bottle jack... Won't budge.

What coulda gone wrong. Should I jump up to 20ton bottle jack?

More heat??

I'm about to whip out my dremel and try to cut the bearing inner ring the best I can. I'll just be careful so I don't nick the pinion splines.

Here is what I'm looking at.

I have two Dana 60 rotors stacked that give me room to drop out the pinion. I just want the pinion out. I'll start over with another bearing... Just want this one out.

I got nothing for you. I've had strange stuff happen.
I once had to beat one out with a 20lb sledge. Ended up bending the housing.
Parts replacement coming up...
 
Well... GOT it out. I pressed it inward again then pressed it out again.

Bearing is ruined. It's blue and feels rough.

Pinion shaft (which is NEW) has a definite wear mark. Maybe it went in crooked or something... Gonna get a new bearing and try again.

Where are you installing shims???.
there is no shim between the bearing and the pinion gear., unless the crush sleeve eliminator requires something different than oem?
pinion depth is adjusted by shims between the pinion bearing housing and the axle housing.
replace the races along with the new bearings, and your rotating torque should be 25-35 in/lbs for new bearings.
use a new nut too if you’ve removed that one a couple times.
 
And looks like dry install . Use some gear oil or grease were stuff presses together.

As zimm said preload only for pinion with setup were your at . The BIG SHIMS for depth go between the case and support housing .
 
Crush sleeve eliminator requires shims to set preload. Takes some assemble, check, disassemble to get it right. Then move to shimming for pinion depth.
This is another situation where a set-up bearing can be handy. Sand or grind the inside to make a slip fit on the pinion.
If the old bearing is in decent shape, use it to get close on the shim stack.
And yes, some oil on the surface helps.

This is a 14bolt not Dana. Crush sleeve eliminator gets you close then shims dial you in

Had oil on shaft. Cleaned to get photo.... Gonna get new bearing and try again.

IT ONLY SETS PRE- LOAD ON BEARINGS in 14ff setup .

Shims between support housing and axle housing set depth .

Thinking any other is crazy . And even if you wanted to try and set depth off pinion setup in housing its only moving it 1 way = out if you happen to have extra shims from other jobs to put under the inner bearing race to pinion housing .

I'm clear on all that. Have my depth shims ready to go!
 
I just put a crush sleeve elleminator in the 01 14bff. The seal was leaking, so CSE and new seal. I reused the bearings , had to try 3x to set preload. My bearings pressed on and off no issues
