Useable cover?

[Greaser Greg]

This cover came with a project bike and I'm wondering how critical the flatness of this surface is. It's where the kickshaft comes through and the washer over the spring retainer clip rests.

This is a different cover. I'm no welder but am pretty sure the heat from a weld will ruin the seal (oil pump test cover if not useable otherwise) and maybe warp stuff.  Am I a fool to consider a chemical repair? Something like jb weld or epoxy come to mind. The clearance to the pump is tight, but I definitely don't consider jb weld inside the cover to be a good idea. It doesn't leak, yet.  What say ye?

welding it will be fine but you would need to remove the seal then replace it with a  new one. however, just clean it a lot and pack the crack with case sealant.  as far as the kickstart boss, just file it where it feels smooth, it will be fine.

I've welded a few over the 35 years or so...Sorry to break your heart you not the first one to lose your nut!

"Pack the crack"!

I would guess that it is OK as it is.  Effectively it's a combo of bush (support) and end float control.

If the kickstarter shaft has too much side end play, put a shim on the shaft and if not, just use it as it is.
