Getrag/HM282 early vs. late differential ID

[Will'sFiero]

I've been told that there are two factory diffs for the 282, and early one with smaller diff parts and a later one with larger diff parts.

What was the changeover point?

If I have a diff of unknown vintage, what do I measure or examine to tell whether it's early or late?

I tried searching for "282 differential" but didn't find this info.

this is the "Late" style from my 1991 tranny, 88/89 was a changeover year If i remember right..



the early ones look quite different.

Thanks.

That looks like all the 282 diffs I've ever seen.

Do you have a picture of an early one?
Can you describe a feature of the early one whereby I can identify it as such?

I thought I posted this yesterday. Did the bandwidth overrun dump a day's worth of posts?

It wasn't a BW overrun (even though that's what it said). And yes, it did dump all posts from yesterday afternoon until about noon CST today (http://www.60degreev6.com/showthread.php?t=38971). If I had know that was going to be the case, I would have shut down the forum prior to the maintenance...

"You have to look close to see the differences in the differentials. I'm not exactly sure where the cut-off point (I understand its around '92 or '93). I had some pics of the differences, but I can't seem to find them now. Heres what I can recall:

1) the outside of the HD diff is all machined
2) the spiders gears are larger
3) the cross pin is narrower, but hardened (the narrower cross pin allows for beefier spider gears)
4) thats all I can remember for now "

sorry for the outside links, but kenton did a comparison on them and posted it up on v6. you might be able to ask him for the information to be put on the wiki
