Pulled the old trans apart last night to get the Quaife out and into the new trans (due to a slight crack in the case and a “funny” reverse gear). I found this sitting in the bottom of the case. Its like a dark grey metalic paste. The middle of that pile is probably close to 1/4" thick. Cant be good. I didnt notice any strange wear on any of the gears etc (that I could see anyway).
Hopefully nothing is wrong with the Quaife. Its going out for a checkup on friday.
Story: they stopped making these for my trans years ago (its actually an Isuzu trans). A guy in the UK wanted one for his [edit: something with a Isuzu 4XE1-T engine, FWD. From what I recall he also had a CF caterham, hence having cash to pay up front for 20+ diffs /edit] and paid Quaife out of his own pocket up front to make 20 (their mininum run). I think 15 or more of them came to the states. I picked up one of them for $750 (basically cost plus shipping and duties etc).
I think the deal was, due to the nature of the deal, they would have parts avail to fix it if needed but they didnt come with the “standard” warrany card.
I talked to Quaife-USA a while back. Apparently for $50 they clean and inspect them. I sort of doubt there is anything wrong with it, but for that little cash may as well at least get any of that sludge out of it.
I know tweety’s had issues with Quaife USA. Sounds to me like they might actually take care of you though.
For $50 + S/H, I’d have them take a look and degrime it. They may even find something you didn’t know about. I had a Quaife before and I was amazed at the level they stood behind the product.
The diff showed up yesterday, clean shiny and new. Apparently nothing was wrong, and it really wasnt even that dirty inside. But they cleaned it all out, put in a new spring pack and sent me new warranty cards.
They quoted me a min of 3 days to process it, I think it took them 4-5 days. Not bad.
Now I just need to get it into the new tranny that is already torn down.
I guess it was worth the $100 (incl shipping both ways to CA and back) for piece of mind.
Finally got my Quaife transferred into the 93 case (I somehow cracked the case of my orig 91 trans). I think the crack may have been caused by the hybrid gear set that I put together not being assemlbed quite all the way, and/or not shimmed right.
I got it all painted up tonight and even took apart the selector “box” and cleaned it all up and painted all the pieces and reassembled.

For those unfamiilar with the quaife. (this is from the first time I assembled it, Im now using themetal vss ring with the 93 trans)
and all back together
Should be bolting it up tomorrow along with the drivers side suspension. Shouldnt be long now and ill be trying to start it.
It probably only took a few hours (4 ish) to clean up and paint everything. Alot of it I did while assembling things. The worst part was pulling the selector box all apart and blasting and painting and reasembling. Well, that and getting 14years of grease and j/y gunk out of the fins around the diff on the case. However, well worth it imo.
Here is an inside shot of all the tapered bearings everywhere.
