Is it worth welding the sprocket on?

(1/3) > >>

dpavelko:
Well I should have just replaced the output shaft as the threads were buggared, so I cut a groove and added a circlip which is nice and snug. The spines on the output did have some wear and there is some very minor slop. I continue to look for an output shaft that is in good cond. and not outrageously priced.

Anyhow I was thinking for safe measures after rebuilding this motor top to bottom, it might be worth welding the sprocket on for this season. Next season I am going to tear it apart and modify it and ultimately replace the output, so I don't care about grinding the weld and trashing that output. Thoughts Ideas and impressions?

Should I tac 3 spots around the sprocket or run a weld around the whole thing?

umberto:
I would worry about the heat from the welding causing the rubber seal to melt and leak and/or let junk into the cases.  Once you weld that sucker on, it's going to be impossible to replace the seal.  Just my two cents.

Larry Wiechman:


I say go for it. Be a legend!

sandblaster:
Hilarious!
I have seen that many times.
Get out the grinder  :lol:

Foxx4Beaver:
someone didn't want that one coming off...

on a different note....I've seen several front sprockets worn out that bad, until it just spins over the chain rollers....and the sad part, the sprockets weren't welded on!....people just being too lazy, cheap, broke.
