Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I picked up a nice clean 3000 watt generator from CL with a small crack in the bottom of the crankcase that allows the oil to drain out slowly (fell off the back of a pickup). Any one have any suggestions/experience for repairs other than welding? I'm hoping maybe Devcon, JB weld or some metal epoxy?
The motor is a clone, Lifan 168F2 196 cc and parts seem to be quite rare. The manufacturer will ship a replacement crankcase for $62.00 + transport, which is probably close to what I would pay to have it welded.
Thanks

I would just Alumiweld it. Should be a lot stronger.

mkd55, - I may still fill those cavities for the extra support.

Bill_H, I looked at the Alumiweld for a long time but the feedback I've seen doesn't give me a warm feeling. Plus I only have a propane torch so it would take a while to heat such a large mass, if it was possible. Plus I am too lazy to strip it right down to the casting so I'd be worried about how the heat would affect the other components, bearings & gaskets.

l would agree money better spent on a new block espically at that price!!!... and i would probably charge $75-125 for a repair like this one.. but if u wanted to repair it...then brazing it in my opinion is the only permanent solution...

I used JB Weld once, it was for filling crack on a ford 302 head it was leaking right front corner , It was not only the gasket, the engine has already 300,000KM so i did want to redone the heads, so I use JB weld and telling you I sold the van and the guy still running it with the repair and still not leaking.
