1955 four speed transmission sprocket torque specification

[goob]

I have looked all over for the torque specification to tighten the sprocket nut and the only info I found was to tighten nut securely. Harley has a spec for all nuts and bolt does anyone know this specification.

I use an impact wrench and tighten till it stops.

FWIW It is inadvisable to use an impact wrench on your sprocket nut.A good American made 1\2" drive impact develops a max torque around 350-400 ft lb . This is pretty likely to damage the nut if you are lucky or the main drive gear if you are not.

I have been putting that nut on with an impact wrench on pans and shovels for 30 years and never have I damaged any threads.

try to find somebody with a left hand torque wrench,most common are for right hand torque.I've done both ways of tighten the nut,but mostly i use the 3/4 ratchet, AND GET IT TIGHT AS I CAN.never strip a nut .line it up with the lock,you be OK.and i 'm sure that it will be looses the next time you inspect it.....johnson
