RE-torqueing nuts/bolts.

[Harry/FDK]

What do you racers do for re-torqueing your nuts/bolts...Do you loosen the fastener and then re-torque, or do you leave all as is and re-torque ?? (nobody is clear on it on the www.).

Thanks,
Harry

Leave as is and re-torque

Loosen and re-torque.

Loosen and re-torque.

Same,although i have done it both ways and never really seen a diffeence,I always use a thread lube on anything that I torque so it is always repeatable

I also alwways loosen then retorque.
Hopefully not the case with someone's racecar, but otherwise you cant know if the fastener is frozen or partially siezed.
And yes, proper thread lubricant is quite helpful

Any retorqueing instruction I have ever read/followed specified loosening first.

Loosen then re torque. I used to do this method years ago when re torqing rod and main bearings on hypo race boat engines.

I've always followed the same method.

Hope this helps

Loosen and re-torque. That is my feeling too, since i ALWAYS use moly-lube, and wait for every component to be set.

I won't address the torque/retorque issue or torque to yield. But... The default torque spec for bolts in general is
CLEAN and DRY. Unless otherwise specified. Not my opinion...fact. If it's critical, you have to go by the book.

There are of course exceptions to the rule, but haphazardly slopping oil/grease on every bolt can be foolish.
