Changing Crank Seals??

M8 motor. What does this involve? Can it be done with the motor still in the sled? What is needed for tools? Thanks in advance.

Unfortunately no you have to pull the motor and disassemble it to install the seals.
A clutch puller is a must,piston puller and a good flywheel puller too and a way to support the motor a good sturdy rafter and a com along works. the rest of it standard and metric hand tools.

Thanks Clutch Man!

Thank you and it may better to put new pistons in when your there, not sure of your miles but you will have to have them out anyway. Also how do you like the RKT Secondary? does it work good for you?

the M8 motor is actually pretty easy to manhandle, you can get it out by yourself pretty easy. I've pulled 1000's by hand no problem, the 8 is cake.


Clutch man, what do you mean by a piston puller? Never heard the term.

New top end will be going in. RKT secondary works great with the stock cat weights. Did not jive well with cutler adj.

You know snowmobiler i made piston pin puller out of a good heavy duty PVC pipe, washers and some all thread worked good if the pin was not stuck to bad. the good old days.
