Flip motor over, remove flywheel, stator, coupler, take case bolts out an lift bottom of motor off. Gently lift crank up, slide old seals off, grease new seals and install. Clean surfaces, apply 1211, put bottom case back on and torque down. Insall stator, flywheel, coupler, done.

Good- but next time wait to remove the ancillaries until cases are together-no need to torque anything out of position or intro junk into the bearings. J. Zigler (new Watcon/RCJS) once told me to get the case halves cleaned up to as close mirrored surface as possible without gouging. It took me time (on 1 stubborn set of Salt only cases) with acetone, a scraper and 000 steel wool- but all the cases I've done are sealed up tight. P.S. no 1411 on the crank seals themselves but grease that journal.

Okay - I know its a couch but its a Yamaha and I do have two Superjets (on which I have done the crank seals as described above) - can the seal replacement job be done on a GP1200R motor as easy as the 701? Anyone have any experience with this? Thanks in advance.

Done it on both SJs in my family - fairly easy job. Did Experimentals (son) last year and mine this year.

Now, what about post #8 in this thread?? :) anybody done it to a GP1200R?
