Yamabond 4 cure time?

Ready to stick my rebuilt engine back in the frame but am a bit paranoid as to how quickly one needs to remate the crankcase halves when reassembling the engine. From the time I started spreading the Yamabond 4 until I finally had the engine halves mated and retorqued was probably 45 minutes to an hour. I'd imagine the sealant had a good 20 or so minutes of sitting time before I mated the halves. Does Yamabond 4 start curing too quickly for me to have spent that much time reassembling?

 

I know that standard RVT has a cure time of 24 hours, and a dry time of a few hours
depending on how thick it is applied

 

You'll be fine even if you took twice as long! 24 hours is about right for cure time.

 

You're well within the window of opportunity for the Yamabond to have cured properly. Yamabond is not an RTV, so it does have a much shorter cure time, but is still tacky after an hour or two depending on what temperature the workroom is.

Next time use Loctite 518 or 515 instead. It cures anaerobically, so you can wait as long as you like before putting the case halves together. It will not begin to cure until you torque the case bolts down. It is also oil soluble, so any squeeze out will just mix with the oil and not cause any harm.

 

Ah, thank you. Peace of mind...
