Hey I was out in my datto today and it snapped the crank pulley bolt.. What causes this?? And how do I get the rest of the bolt out that's stuck inside the crank????

Also now looking for a new bolt if anyone has one cheers

to much vtech... i have bolt, well i could rape one off if you cant get one,getting it out will be fun

is h/balancer cracked along keyway(seal area)as well,bolt may come out easy, if thread lock wasn't used,was thread locker used on bolt when fitted,

Yea green dog how much u want for it??

Bige I haven't taken the h\balancer off yet but I'll check.. I think loctite would of been used since it was built at a engine builders shop.

Loctite was used I've snapped 2 or 3 ezy outs in there wtf can I do??? I got it to turn about 1/4 turn but that's it.... Anything I can try I need my car in the morning!!!!!!

maybe you need to add heat, work it backwards/forwards, but you will need to remove seal first. was balancer cracked.

be careful with heat ,that the oil doesn;t caught alight.

What engine is it? A-series do not use harmonic balancers.

Quote:
Incorrect tightening, too much torque will weaken the bolt. Vibration will snap it off. Use a torque wrench with the new one, and use a genuine Nissan bolt. Or a 10.8 (high strength) bolt.

sorry; main front crank/fan belt pulley.( its known as a balance in general talk)

It's the crank pulley.. How do I get it out??? I've tried everything!!!! Need my car running tomorrow!!

2 levers gently work it, they are not a interference fit(size for size), so should come off easy.


if its that tight, it shouldn't come off. "rough way" but put a small weld on it, to get you out of trouble for now
