Listen to Tim!

So, the only thing you're going to have to deal with is the spacers for the bearings? So cool...

Order some good fluid and get this moving... I'm going to start looking for an E36 differential

Well Brady, I think shimming it out is going to be the hardest thing yet.

As you could see.. the diff with the ring gear sits more to the right side. I'm going to have to buy that cnc'd piece that one company will sell me to space it out mroe on the left.

hahahahah. yeah, maybe.

And I wouldn't buy any e36 lsds just yet. I wanna make sure i could finish this up. The part i'm getting is through a hook-up, I still haven't talked to them yet, so i don't know if they will be willing to sell this product to the general public. The grinding was the easy part, i just lagged it. It could definitely be done in about an hour or two with the right grinding stone. Finishing this up, and shimming it up will definitely take more effort.

Raj,

Quick question. We were goofing around with mine today. From your pictures, it looks like it's just the one side that needs shimmed, right? We were guessing 3 ways of doing it. Spacing out the bearing, which seems like the hardest idea. Having a spacer cut to put on the flange that holds the bearing onto the LSD, or having a new race machined for the one side. I guess I was wanting to know, do you think you're going to have an issue with the output shaft clicking in?

Wait, does the CNC'd piece shim out the ring gear to bump the whole case right in the middle?

No... that can't be right. We're guessing the best thing to do is to either space out that flange from the body or have a new race made.

Yes, only one side would need to be shimmed as the carrier sits more right.

As far as the output shafts go; i already checked with the carrier and the splines are correct, and it will click in. As far as will it click in when the carrier is in the housing and it's spaced far... that i'm not sure. i'll check it out tomorrow, as i have another day off.

And then the CNC plate i think spaces out the bearing on the left side. If you look at the e36/e30 lsds, they have a removable plate that holds the bearing. I think the cnc plate they have will space it out. I'm going to try and contact the diff place tomorrow and see if they could answer some questions of mine.

Tomorrow i'm going to try and mock up the diff with the race & everything (if i remember how to put it back together). and see what problems we will run into.

Awesome, that's the plate we were thinking about spacing out. I'm sure I could have a machine shop do that for me. Super cool.

This is going to work out splendidly...

PS, you'd better get this going quickly or I'm going to have this done before you

Woot. Found one locally. Too bad I'm broke. If I can come up with a few bucks, it's mine...

I'm getting someone lined up to make me the spacer...

How thick does it need to be? Can you get the exact difference in height between the 2 units? I guess it'd just have to be the exact difference, probably needs longer hardware, too.

Well, I don't know how to correctly place/line up the input shaft, so i wouldn't be able to get you an exact measurement. I have to go read up on how to rebuild a diff, so i could make sure everything is good.

I'll also mock up hte diff today, so i'll update later today.

Measure without the shafts in. Just do from compressed bearing to compressed bearing, if you can.

If not, no worries, I can do it when I get it in hand. I just thought I could get machining started. If you can't get one through your hookup, I can have a couple made.
