Default Struggling to remove crankshaft pulley bolt - 05-10-2007 , 03:02 PM






Wifes head gasket went a couple of days ago. Ok, I thought, lets get the
head off and see the damage, shouldn't be that hard...

Except, unlike my car, the crankshaft pulley bolt will not budge. I am now
up to a 2 foot breaker bar, with the car in 5th gear and my wife on the
brakes to keep the car from moving, and the bolt still insists on staying
put, despite the fact that I am making the breaker bar bend like a banana!

The problem seems to be the combination of the torque required and the fact
that I cannot lock the crank (there is still a lot of movement despite being
in gear and the brakes applied).

There must be an easier way, surely?

Andy.

Breaker bar on, stand clear, turn engine on starter

depending on the vehicle: lock the ring gear with a lever. use an air
wrench. put a spanner on and turn it on the starter.

Remove spark plugs first.

Just a thought..... it's not threaded the other way round, is it?

You could just be tightening it further.

Almost certainly got threadlock on the threads. You could try to heat up the
head of the bolt carefully. Enough heat will soften the locking compound.

is it a honda by any chance ? because they are 'kin tight. some vehicles
that we have trouble with we use a big windy gun, but check its not a left
hand thread as well, also as someone posted, it could be just a case of the
lockthread holding it tight!!!

Thanks to everyone that replied. Heat didn't work (there was no thread lock
or corrosion), but the starter motor trick worked a treat!

What on earth do they torque that bolt up to?!!

Andy.
