Annoying knock from camshaft front pulley area

[Howard Wright]

Hi Lowbarn

I would be very tempted to take off the retaining plate and test fit the flywheel. I can’t remember if there is room to get a feeler gauge between flywheel boss and race but if not put a small dab of plastercine  or blue tack between the flywheel boss and the bearing race.  The reason for this is to ensure that when you tighten the flywheel nut you still have a little room to ensure the flywheel pulls up hard against the taper. You should still have a little blu tac between the flywheel and race indicating the space you have for the taper to pull up. 

Ideally the oil thrower has tiny dimples that can flatten as you tighten up the nut allowing full engagement of the taper and also holding the thrower. However if you don’t have the thrower it is possible that the original engine builder was happy to trust the modern lip seal.  Others may comment on leaving the thrower out but I think any gap between flywheel and race may allow the inner race to move and it may spin on the crank journal later down the line.

I wouldn’t use grinding paste with the bearing in place. As mentioned before a light smear of Loctite 660 will do the trick.

Cheers
