The case for my 175 had been damaged at some point in the past. It looks like the chain came off the c.s. sprocket and really caused a ruckus. The boss for that sidecover as well as some of the case was broken off and has been rewelded. It was a decent job but you can see daylight between the two case halves and it looks like a gap to great for hylomar or any other case sealer. It should be welded and machined but I don't have access to either service in a resonable amount of time. Is there a gap that would be too big for JB weld to fill?
