Had a issue over the weekend the drive locked up. I initially thought I'd run the clearance to close on the clutch so I pulled it apart far enough to add 2 more thin shims then reassembled. Ran it for probably half an hour and it did it again. Then once more I stripped it and added 2 more shims started it and as soon as I went forward to reverse a couple of times it locked up again.
So then I completely stripped it looking for the issue what I found was the bearing between the clutches that works the forward to reverse was working its way off the back of the plate continuing to take up the clearance and locking it up. This was already damaged because the previous bearing had locked up and chewed up the mounting area. I had centre popped the area and araldited the bearing in position. It still managed to come loose so this time I had the mounting spigot machined off and used an older anniversary model bearing setup where they have just a alloy insert with the square hole making t a separate piece completely now from the 2 clutch plates. After reshimming all seems well now.
