Crankshaft pulley help?

[Ren89 0]

Hi, I'm trying to loosen and remove the crankshaft pulley bolt but it's very tight and I'm unsure of the direction I should be loosening it? don't what to damage anything.

 

Cheers Craig.

You need either a rattle gun and/or lock the flywheel and use a breaker bar. Normal RH thread. Cheers

Lefty loosey, righty tighty. 

 

Don't try to use the timing pin holes to undo the crank bolt though, best way to get a proper flywheel lock that bolts to the gearbox after you remove the metal plate between the engine & box or you can do the same by jamming a decent sized screwdriver in there.

Could be hardest grade loctite/thread-lock used on the bolt threads + too much "Nm" who ever did it previously , in that case i'd heat up the bolt with blowtorch first to soften the thread-lock then try to undo whilst still warm ..

 

As Graham says , lock the flywheel if working with hand tools rather than the air gun ..

Agree with the above...

 

One thing to add, when you get the bolt open, do not hit the pulley or try to use a puller on it. You will break it (ask me how I know..)

 

Instead give it WD40 and time, it is not tight on the shaft once the rust has been softened with WD40.

 

Also some heat can be applied if necessary, but no violence.
