Kz1000p case crack
07 Jul 2024 12:24
What are y'all thoughts on this small crack on the shift shaft boss? Not really sure how that even happened, from what I can tell this engine has been given at least one shade tree rebuild. I know it can be welded, but is it even anything to worry about? Also, the lower engine case to oil pan mating surface looks like it's been dragged across the concrete, does it look fixable? I'm thinking probably a wet stone to clean some of it up and a little extra RTV with the gasket.

The transmission cover has a seal. The sprocket cover has two more. The shifter shaft goes through all of them. If the sprocket cover has a sloppy fit the shaft will move around putting side pressure on the inside pivot causing a crack like you have.
BTW the sprocket cover seals are inside and out act as a bearing as well. It is a tight fit in between them that acts like a bearing also. I've never seen a crack like the one you have and the KZP has linkage so there shouldn't be any lateral pressure like a shift lever would. I'd check all the other things I just talked about before repairing the pivot boss.
Just a suggestion.

I was thinking it was in an accident, repaired then sold.

I do have a whole another donor engine that I could tear apart and see if the case is any better, but judging by the condition of it I'm pretty sure that's not going to be the case. Its been, shall we say, abused just a tad.
