What are the torque specs for a clutch?
All Clutch Torque Specs are to the best of our knowledge. We research service manuals for all these specs, but manufacturers have been known to change them. 2010 and older models torque the secondary (driven) clutch to 44 ft/lbs.
What kind of torque does a Yamaha four stroke have?
Newer Yamaha four-stroke models specify tightening procedures for some applications not previously used on older models for similar applications.
What to look for in a Yamaha clutch?
Check the coolant hoses for worn spots or leaks and also check the coolant level. If you see any drips or low coolant level it could indicate something’s wrong or on its way to failure (if not already there). The primary clutch on a modern Yamaha is no different than any other primary – it has bushings, weights and springs and they all wear out.
What causes a Yamaha Bolt to over torque?
The cleanliness of the threads, oil or no oil on the threads, or socket extensions can lead to under- or over-stretching of fasteners. Applying an initial low torque value followed by turning the fastener an additional amount, typically 90˚ or 180˚, will more accurately stretch a fastener to its design limit.
