SX/SXi/SXi Pro Flywheel

[SP33]

I put my flywheel on my Sxi back in Nov. I have not ran the ski yet. I was thinking about this the other night…how tight does the flywheel have to be on. I used wrenches and tightened the flywheel on secure. Should I of used an impact wrench?

theres a certain torque spec... not sure what it is off hand


personally ive never torqued one on. I just make it really tight n have yet to have any issues.

Yea, I use the german spec of gootentight, works good for me. If I have a impact handy I LIGHTLY snug it up. Last time I did mine I didnt have the motor out and tried the rope in the cylinder and it worked fine but I will prob never do it again just because of the risk involved.

My book is packed up, but if I recall correctly it calls for 45lb/ft. I agree with previous posts, german method seems to work without issue.

My 750sx manual suggests 125 N-m (13.0 kg-m, 94 ft-lb). Flywheel tightness is important to not screw up. Use a torque wrench, lock the crank in a vice or stuff a rope down the spark hole to keep it in place.

Sounds high but if thats what the manual says than thats what it must be. Good info man.

Don't use an impact, use a torque wrench.
