clutch hub re-build help needed
I've stripped the clutch hub down ready for an APE re-build kit but the inner plate has deep ridges in it from the hub springs. Are the plates available? Or can it be repaired in some way? I thought maybe the ridges could be filled with weld and ground back?
Anybody got any ideas?

IanM63, I've seen this before. The bike must have done a lot of work to get to that stage.
I suppose it could be brazed looking mainly at the clearance of the surface to ensure it doesn't scrape on something once it has been built up.
The other alternative is to grab another assembly and dismantle it.
The Ape rivet pack has over-size rivets, if you can get new rivets made of the original size life is much easier, as you don't have drill all the washers etc that go to make up the assembly.
You can get the old rivets out by drilling just undersize the grinding and punching out . This leaves a neat hole in all components (no more drilling).
Take care when dismantling to note which way and where the bellied washers go.

The other has worn right through where one spring sits..
Common as much is Oz with high mileage thrashed bikes, it's all to do with our wide open spaces, long distances and good beer.
Forum member GEZ635 is your man, might be able to help with repairs or new springs/rivets.
As GarnZ1R states, probably better to source another good second hand unit, but you take a big gamble and hope its in good nick, it's also cheating, nothing like a challenge and hope the fook your repairs hold up.
I've seen 3, repaired 1, still going strong but mileage will tell as I,m not sure about the weld repairs just yet.
Tig weld up all the ridges then grind out with a rotary de burr tool, you know the one that goes in a hand held drill, I can,t remember the size but can find out at a later date as I busy on night shift for a week or so.
Write down the order as hub is stripped, if it's too late, I do have the order of assemble recorded, it's critical.
This one was removed from a 73 Z1, as can be seen had been weld up and ground out at some stage and others are worn, but believe me it did not rattle and preformed as normal, it was replaced in an engine rebuild, other wise would still be on the road today.
This ones otta my Z1B, It was then tig welded up, gound out and still going fine today after about 2,000 miles.
