Cheers

undo bolt and slide it off easy as pie

[justice4all3000]

yeah but how do I stop the engine from turning over?

[plymouth_hemi_69]

2 easy ways are 1 put a socket on and a breaker bar and hit it with a heavy hammer or 2 pull efi relay slide pipe over the breaker bar and rest it under the drivers side chassis rail and hit the key

Hey thanks for the input but how would I re-tighen it I hear it has to be really tight

I found that unbolting the starter motor and jamming the flywheel was the easiest way for me to keep the harmonic balancer from moving. I tried the breaker bar under the chassis rail trick and bent my breaker bar

Be aware that you might need to get a puller to get the balancer off with though. There was no way I was able to remove the balancer without using a puller.

Undoing the bolt is easy; rest a breaker bar attached to the crank bolt against a chassis rail with a wadded up rag in between to protect the rail. Then disable the engine by removing the "eng comp" fusible link or crank sensor plug or all of the injector plugs and crank the engine over to loosen the bolt. That's hard on the negine mounts and starter but works.

Doing it back up again is more difficult. Probably best is to hold the starter ring gear using a flat blade screwdriver in the teeth and against the trans bell housing, from under the car. Really tricky would be to make a tool to hold the ring gear from a segment (~50mm would do) of another (old) ring gear (flex plate) to mesh with the teeth on the one in the car - not worth doing for a one off though.

If you are not replacing the pulley with a new one, the best way to ensure that the bolt is retensioned correctly (without a torque wrench) is to mark the relationship between the bolt and the pulley before removal and match the marks after reinstallation.

I used a nice big 1/2" drive torque wrench to tighten it up with. Can't remember the torque it's supposed to be but if no one else knows it I'll go out and get my manual to check. I know it was also a lot harder to jam the flywheel when trying to tighten it than it was to loosen it.

just checked and it should be 270-325nm

Using a torque wrench is best - if one is available. For VP V6 the tension is 270-325Nm.

A series 1 VN V6 has a pulley which is a slip fit - no puller required.

One thing that I forgot is that the sealant in the keyway on the pulley has to be replaced to avoid an oli leak.

hmmm I think this job is for my mechanic
