Cracked aluminum crankcase repair options?
Original Message   Nov 21, 2012 9:50 pm
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

Niper, Not to be rude, but would you be able to braze this for a customer for less than the $62 crankcase replacement?



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.
