Reassemble T500 engine -- Any tips?

[Stan]

I am preparing to reassemble a '72 T500 engine after it sitting in pieces for 18 months or so. I am not the disassembler, so am flying somewhat blind, but with a repair manual. I have a specific question, but would also welcome any tips or thoughts you might have.

My question is this: should I use liquid gasket or gasket shellac on the mating surfaces when I assemble the two pieces of the crankcase? The repair manual seems to indicate that I should, but the previous assembler did not seem to do so - the mating surfaces of the cases are as clean as can be, showing no sign of gasket goop. I would appreciate your thoughts on this.

As well, I am open to any other thoughtful tips you might have on engine reassembly. I appreciate all counsel.

Regards,

STAN

On the 750's the cases are sealed together with Three bond. I used Yamabond that was available at my local dealer and it worked great.

I've also previously used the ThreeBond, with great results. I'd say you really should use this (or an equivalent product of your choice), since on any 2-stroke sealing of the crankcases is very important (since the fuel-air mix is moving through there, you don't want any leakage), it will really cause problems running. Just take your time, apply it carefully, you just need a very thin bead, and then get the case halves mated before it dries too much (you've got at least 20-30 min to do this). Clean off any excess with a rag dampened with acetone. Also be very careful to double-check everything before you mate the cases, or you'll get the chance to take them apart & do it all over again, like I did on this Kawasaki Triple, see photo below.

Thanks for the guidance. I guess I wil use a liquid gasket to seal the two shells of the crankcase.

Any other hints or tips for me to watch out for?

Again, thanks.
