Hi Sh2006,
Wow your machine has certainly copped a bit of abuse over the years, rest assured that cast iron can be successfully welded and have it's integrity back in tow. I guess it's getting someone with the ability to do it.
As far as that clutch body wear is concerned I'm a tad skeptical about it. The transfer shaft does show signs of unusual wear but really it shouldn't protrude in that far.
Personally I would replace that clutch half as its an early diecast unit of which they weren't that good compared to the cast iron units.
The is a chap in WA that is now re-sleeving them but I'm not convinced that this is the way to go as you lose the key steel on the PTO shaft and thus you really have to pin the clutch body really hard into the PTO shaft which always makes it hard for later removal as the shaft is damaged by this practice.
I'm going to have a look at a parts machine I've got and look at this shaft protrusion issue.
Cheers,
BB,
