Hello,
I am about to go down the journey of replacing the crankcase seals. This means I need to remove my engine from the frame and gain access into the crankcase / transmission. Can anyone suggest the best method for splitting the two haves apart?
Also, best sealing product to use when re-marrying up the two sections of crankcase, I think it quotes Suzukibond in the manual, I will use this if there isn't any better substitute opinion around the forum.
Thanks

I've always used yamabond 4. Did not even think to check if Suzuki made something.

If you're just trying to stop an oil leak, you can replace the external seals without splitting the cases.

Anyway, the process for splitting the cases (bolt diagrams and such) is laid out pretty clearly in any of the shop manuals. In general, make DAMN sure you've removed ALL the bolts, even the awkward ones inside the oil filter cavity, heed the advice to NEVER pry between sealing surfaces, make use of lots of VERY GENTLE taps with a rubber hammer, and go slowly and evenly -- you can't pry one half apart and then the other. The dowel pins are usually corroded, so make sure you know where these are and concentrate your efforts around them. Excessive force is not required, so if it's not moving, you missed something.


For case sealer, I use ThreeBond 1194 :

Works great, and one tube will do many engines.

Not sure what's available in Oz, but that should put you on the right track.
 
Thanks for the advice, I have the issue of the engine oil getting into the transmission and leaking out through the breather vent, hence need to replace the seals on the transmission drive and counter shafts. Thanks again for your help
