This gets asked a lot, so here they are according to Nissan workshop manuals:

Rb26:

Balancer Bolt - 446-466nm (ouch!)

Flywheel Bolt - 124-152nm

Clutch Bolt - 34-44nm

Rb25:

Balancer Bolt - 142-152

Flywheel Bolt - 124-152nm

Clutch Bolt - 34-44nm

that's awesome duncan, thanks. That's some crazy ass torque setting for the 26 balancer bolt. Any idea what size bolt it is?

good luck getting 450nm on the RB26 bolt without a tension wrench designed to do wheel studs up on a Euclid 170T dump truck.

I do them 150nm then get a pipe over it for another 1/4 of a turn....never had one come loose.

DO NOT put Loctite or any other anerobic compound on them. ARP moly lube only please.

Thanks Johno.

You're pretty safe if u torque up the bolt to the above specs, loctite won't hurt, more of an assurance, but sucks to be the next person to rip the bolt out...haha.

(in saying that, some people are quite religious about using loctite)

just looking over this ... the balance bolt should be replaced with every clutch . i've looked at the threads on 25's and 26's and came to the conclusion it was a stretch bolt because it thins out close to head of the bolt. its just good practice . get it the right way first .

Pole was 4 meters long=sweet!

I think it was 17/19 on my ARP flywheel bolts.

[Duncan]

factory flywheel bolts have a 19mm head, and factory clutch cover bolts have a 12mm head

Anyone know the thread size for RB Flywheel bolts? Bought my RB20 for $20 and it has been sitting outside for the last 5 years so has some rust/filth in the threads in the crank. Looking go buy a tap to clean them up. Cheers.

whoa good searching.

rb26 is m12x1.25

SAU has a terrible search function but I was on mobile and it is even worse. Thanks for the info.
