Attention Transmission Gurus,

[s'ko]

Can a full time center diff from a GL10 be put in place of the center diff of the EA82 5spd D/R?

I was kicking this around in my head last weekend and before I tear apart two transmission I wanted to see if this was even possible.

I've been researching a similar idea.

 

The biggest obstacle I can see is that the Pinion shaft on the Fulltime boxes(and newer AWD) boxes is WAY fatter. So is the bearing. Makes sense since it is actual 2 shafts, one hollow, and the other inside it.

 

So the case halves would need to be swapped. Which would only work if you're fulltime box was from an RX ie. Dual range. And if that was the case, it would be easier just to swap the 1.59 low range gears and leave the rest of the Fulltime box alone. No way to get 3.9

 

OR...... the D/R box machined to accept the larger bearing (this is what I intend to do)

Yeah, it's coming from a single range GL10 box. do you have pics that you can post or send me showing what needs to be machined?

 

Thanks

The bearing on the lower shaft, left side of picture (rear of trans) is the one that is larger in the FT4wd/AWD boxes. Not sure, but the front bearing on that same shaft may also be larger.

 

So those 2 bearing seats need to be enlarged on the D/R case to fit the larger bearing. From 71 to 74 MM

 

I'm planning on taking both halves of the case empty, but bolted toghether to the machinist and have it *line bored* like would be done for Crank or Cam journals

 

DISCLAIMER.....THIS IS ALL IN PLANNING AND R+D STAGES.....This hasn't been proven to be doable yet,

I uploaded the picture for those whose companies have photobucket blocks (like mine)

 

Please let me know when you plan to get it bored out. I called around my area and a machine shop said that it would be mostly labor costs and he guestimated $150-300. There's a lot of soobie parts to be had for that kinda cash.

 

You have to replace the entire gear set to get the locking center diff in there? If that is the case, you are stuck w/ 3.7? There has got to be a way to remove the pinion and put a 3.9 onto it. I plan to split the GL10 tranny anyways b/c I need to get to the 25 spline stub axles in the front diff. Will take a look at them side by side so I can see what you are talking about.

I'm a little confused. There is no center differential in a "standard" (non-RX) D/R tranny.
