Title: Castellated Clutch Nut - how tight ?
Post by: McCabe-Thiele (Ted) on October 09, 2020, 07:52:01 PM
I've been looking for a torque setting for the above nut - does 30Lb-ft sound about right?

Can't say it's 100% but one of the manuals I have has these torque settings:

So 30 looks ok.

Thanks Deano one of my manuals does not seem to say or calls it something else the other had a figure like your chart but it seemed a tad on the low side - I guess I'm used to torque figures on cars that tend to be somewhat higher. Also its out of range on my old Britool torque wrench.

Start at 30 and if the locking tabs are not lined up to bend over in place than, you tighten until a tab has a home to sit in  ;)

This is the official work shop tool from the 1970's which may give a clue to how much torque is needed.

Thanks guys that very helpful. I'll nip the nut up when my new torque wrench arrives my old Britool Torque wrench is a good 50 years old but the scale starts at over 30 lb ft so decided to treat myself to a lower range wrench that I will need for cylinder head bolts etc.

I had the Britool recalibrated a good 30 years ago when it was fitted with a new spring - I always undo the adjuster so there is no tension at rest. Sadly I tend to use impact torque sticks on our 4 wheeled vehicles - its just so easy!
