Probably not a new topic.
« on: December 21, 2019, 08:38:38 pm »
1971 CB750K1.  Need torque specs for engine mounting bolt and rear axle nuts.  I've searched the manuals on this forum, my own shop manual, google, bing, etc.  No luck yet.  Any feedback is appreciated.

Rear axle nut: 20-24 ft-lbs.  Don't crank it so tight that it stops turning (that's AKA as "Harley tight"): this will eventually wear the bearings on the far side of the nut (sprocket carrier) and the brake side.

Engine bolts:
Top rear 18-22 ft-lbs.
Lower rear/footpegs: 22-25 ft-lbs.
Lower front bolts: 12-16 ft-lbs (smaller bolts up front). These can also strip if overtorqued, due mostly to age of the threads (50 years) today!
