rickster1971 Posted May 12, 2013 Share Posted May 12, 2013 I need to get some sealant to join my crankcase halves (RD350). I've read online and watched on YouTube that I should use a rubber based sealant? Anyone got any recommendations? Three bond has been mentioned but this appears to be silicone based? Standard off the shelf instant gasket isn't suitable? Link to comment Share on other sites More sharing options...
dt502001 Posted May 12, 2013 Share Posted May 12, 2013 Three bond and yammabond are what I'v always used never had a problem with either,rebuilt many a 350 with both. Link to comment Share on other sites More sharing options...

dt502001 Posted May 12, 2013 Share Posted May 12, 2013 1104 threebond,on my wr250f I used permatex "the right stuff" instant gasket worked great.Makes any gasket in 1 min. as fast as you can assemble and put to use it seals amazing stuff. Link to comment Share on other sites More sharing options...
YPVS TONE Posted May 12, 2013 Share Posted May 12, 2013 Threebond 1104 is the same product as Yamabond # 4 which is what Yamaha recommends in they're service manual for the 350 YPVS for joining the crankcase halves. Link to comment Share on other sites More sharing options...
