Front Hub Nut Torque

[GTRMikie]

Whenever I come to torque up the front hub nut, 99 times out of 100 the split pin hole does not line up with a "cut out" in the castellated nut. According to Haynes it's just a matter of torquing the nut to 188-200 lbs/ft then tightening the nut further until things line up. What sort of torque can the nut/thread take? At 200 lbs/ft I've still got someway to go before the holes line up! Is it safe to back the nut off or should I use my 250 lbs/ft torque wrench to its full extent?

i'd be tempted to drill the hole through the thread once 200 lbs has been applied if the hole is a fair bit off lining up.

The problem with putting another hole in is that you will make it more week. Clean and lubricate the nut thread befoe putting it togther. If you only just past the hole go back if not it is ok to add futher torque.

Actually the torque is not that specific. it just has to be very tight. Anything from about 140 lb.ft. to 180 lb.ft. works fine. One way of getting the slots in the nut to line up is to remove the nut when you reach the torque you want but the slot/hole doesn't align, and linish a bit off the back face of the nut. Repeat this until it lines up at an acceptable torque.

I must have done hundreds of mini hub nuts over the years and never had a problem with tightening up until the next hole aligns.

I've never had trouble with drum brake hubs because they have extra holes, it's the disc brake hubs that cause me problems. I'll try the lubrication method plus a bit more torque first, then go for the linishing.
