Broke a bolt on my primary

[JD]

Just tightening down the last bolt on my primary cover…..bang ….the little bugger snapped….had the wrench set to 10ft lbs…..Anyways EMERGENCY….anyone know if the RX-1 has that bolt somewhere else on the sled that needs it less then the primary….

Bolt: Yamaha part # 97017-06030-00
1.25’ long X 4.54mm dia (thread pitch 1.0 metric)
Has a large 8 on the head…..


Thanks…..JD

i think there are similar bolts on the sled, but none exactly the same. its important to replace this bolt with an exact replacement, as its weight is part of the clutch balance. if you cant get one right away, replace all 6 with same size metric bolts from a hardware or auto parts store. this will get you going till your dealer gets a replacement.

If you replace them all with hardware bolts, how would you know what hardness you are using? I would shy away from pressing her hard with odd bolts in her. But, .. who knows, she might just like a new hardness. Anything's got the be better than the limp one you had in her. Just kiddin', eh?

Two things to consider;

1) Those bolts are NOT subject to high stress. Just the force of the spring under full compression. So any correctly sized bolt will do.

2) You do NOT need to replace all 6, just the three that are equi-distant around the circumference in order to maintain balance.


FYI: You don't need to worry about making perfect torque on them, don't break them and the loctite will do the rest.
