Rb25det Crank Bolt

[DamageInc]

ive done a search and cant find anything , just wondering if anyone knows what size etc the bolt is

goes in the front to hold the harmonic balancer onto the crank

im pretty sure the end is 27mm but i need to know what thread and how long etc so i can go get one from coventry

cheers in advance !

you can just buy one from nissan. not sure on RB25 but RB26 is 12309-05U00. cost about $10. and if you're replacing the bolt replace the washer too it's 12308-05U00 and cost even less. and a good idea to replace the backing plate too if that was worn, 13023-05U10. the whole lot should only be $20.

it's a bloody important bolt and gets some serious torque on it. I'd buy genuine for sure.
