Two steps i never heared. Why? Its better to balance all to zero....
I remember my crank being balanced first on it's own. Cause I took the other parts to him afterwards..

The flange does not come between crank and flywheel.
It's a big washer (is this the correct name?).
Crank - flywheel - washer - bolts.
Correct torque is a must have.
Clean threads too!
Imbalance can cause this. Low torque on the bolts too!
Using blue anti vibration loctite.. Bolts torqued to 85nm so just slighly over and yes the washer is behind the bolts i no this as i built it..
The edges of the "bearing plate" that goes under the flywheel bolts could be bent up against the flats of the bolts after you have torqued them up, to lock them in place. Fiat haven't used the plate as a lock plate, but other manufacturers do. Maybe this would help.

Use a gauge and check the roundness/flatness of the flywheel when it's mounted to the crankshaft.
When it's balanced you don't feel it but with clutch and gearbox you can have some forces which you don't want.
Last main bearing is ok - clearance etc?!
83Nm is stock torque. 95Nm for ARP.
Opel/Vauxhall tuners uses the same bolts and here it's 110Nm torque...
i ask my mechaniker today, he told me 120Nm (~85ftlb) for the flywheel bolts
and he also using a prisoner too, not just the bolts holding the flywheel
A pin or what? Like stock?
120Nm sounds to much but depends on the bolts I guess.
Yes a pin, but on Crybaby's UnoTie he uses two pins and the bolts are torqued to 120NmOriginally Posted by Acki
On the pic i had link here 2 pages ago, the flywheel has that pin (one)
Without it the bolts holding the flywheel
Crybaby's UnoTie also had ~same problem years ago, bolts broken from the power without pins
The crank has the holes for 6 bolts and for the pins, the flywheel needs to modify
am i reading this right you have to drill the top of the bolt and fit a dowel to stop them unlocking ,
found from another forum
If you use loctite on the flywheel bolts (I do), fasten the flywheel down with a few of the old bolts first (I mark them with crayon) and then install the new loctited bolts replacing the old bolts as you go along. This will keep loctite from getting between the flywheel and the face of the crank. I can't remember who told me this but it sounds like
