Hi All

I have a small issue I need some advice on please. I have torqued up the main Crank pulley bolt to 466nm on my GTR twice now, using loctite on the bolt the last time and it keeps coming loose after a few hundred km of driving. Can anyone tell me if this is the mistake, using loctite, or is there some trick to stopping the bolt from coming loose? I am not the only person owning a GTR who has had this problem, a few of my mates are having the same problem, can anyone shed some light please?

Many thanks
Gordon

Standard pulley on an RB26 ? or is it something different ?

You've not got an OSG RB30 have you?

Is the wood ruff key in good condition?

Measure the length of the bolt... if it has been used several times it might be streched....
