I was looking at some old instructions for a Bosscat pro-diff. Don't the diff washers have to be superglued to the alloy carrier? Thanks for any advice guys.

Mechanically speaking it shouldn't need glue to work. The diff should be tightened enough so that no parts will slide relative to each other but the plates will still rotate the balls in the diff.

From an assembly point of view I can see why you would want to do it but I think there is a risk that the glue doesn't set properly or some breaks away. In which case it might work into the diff balls and contaminate the grease. This could cause advanced wear in the diff.

From memory these balls diffs are a bit of a pain to assembly, hence why they were normally assembled already in the new kits. Hopefull once you start tightening up the components the components will self align. Give it a go and see how you get on.

Thanks. I sand both sides of the diff washers with 600 wet and dry. A glass table is a nice flat surface for doing this on. I also use ceramic balls and disc springs "a la Borma" like so )()()(

These were left out the original instructions so I wonder what else was left out!

Will run the car and post photos and video (eventually)

I am quite certain that these diff rings are not meant to be glued and should almost have a little extra slip between the washer and the carrier. From memory the earlier version Cat items were held in place with abrasive sad paper type discs but these dont require any glue. If they were meant to be solidly ounted they would have keyed them like they do with the tri-lobe diff set up.
