701 Torque specs

[enzo]

Lost my manual! Could someone give me the torque specs for the flywheel nut, case bolts and cradle bolts.

Thanks. :smile:

Case bolts: 1st 11 ftlbs, then 22
Cradle bolts: 1st 17 ftlbs, then 34

Flywheel bolt: 55 ftlbs (I think..somewhere between 50-55)

Cool, Thanks! :biggthumpup:

I thought the flywheel was 75ftlbs???

Not per Yamaha manual. However, I have seen pro-builders recommend 75 ftlbs on modded, high output motors.

I accidentally went to 65ftlbs on my MSD flywheel this past weekend, and I was extremely uncomfortable doing that. I can't imagine going to 75. But I am not a pro, either - they know what they're talking about.
I have been running mine at 55ftlbs for over a year - not one problem.

I know on my dual magnet flywheel, MSD reccomends 65 ft lbs.

My flywheel is a RAD charging...Does that change anything?

Call them. Honestly, in my experience, 55-65 would me more than enough. But, keep in mind, I am not a pro.
I am, however, extremely queasy about torquing that aluminum bolt to 75ftlbs.

i did my rad to 75, well the friend that had the kawi puller did this actually
no damage was done but i was way nervous watching him do that

u mean using an imact gun is a bad idea?

70-75 ft-lbs is o.k. on superjet 701-760 motors...as long as you are using a OEM bolt and have good clean threads in the crank.
