Flywheel bolts - shorten or washers?

Hi All,

Fitting my lightened flywheel and the bolts are a smidge too long (lock the crank).

Would it be best to cut the bolts down slightly or place a washer under the bolt? Would it affect to torque used to do them up?

Cheers,
James

Cut them down if they are too long, do not use washers.

As long as you dont cut them too short it will be fine.

Not sure about loctite as they are ARP bolts that come with the ARP lube stuff, not sure if that works with loctite....? I assume not...

No need for loctite. Make sure you torque them correctly with a good quality torque wrench.

Also make sure the holes in jour flywheel clear the chamfer on the bolt heads. Worth sticking a countersink in each bolt hole to put a 0.5mm chamfer on each to make sure.

/ wot he said
I've used locktight on flywheel bolts - and never had any come un-done

...or get some bolts from an Automatic version of the same engine - usually about 5mm shorter that the manual versions (or is on a Zetec anyway!)

Yeah I have the auto bolts already - but the Tiger flywheel is thinner and there in lies the problem!
