Are you talking about the clutch outer basket?For some reason, all of the Yay Area Triumph dealers had a two-week wait on clutch cover gaskets. Finally got mine this week, finished taking apart the clutch, aaaaand... yep. Broken pin on the gear shift mechanism. Swapped washers, new spring, insert, and good to go, right?
Wrong! Apparently, you can get a PhD in clutch basket installation. I've watched videos and read forum threads to no avail. How the hell do I install this thing?!
Did you use something to keep the backlash gear aligned as I suggested?
If not you'll really struggle to get it back in, I was lucky one time as the gears we're nearly aligned anyway but second time was impossible. Also don't forget to to make sure the drive for the oil pump is engaged, you can turn the small chain by hand as you fit the basket.
PM me if it'll help.
