Many of you will know of my recent mission to unseize my 4.2 vdp. To do this i basically drilled through the crankshaft damper or pulley to get serious leverage on the crankshaft. It worked. Engine is unstuck. My query is do i need to replace the damper/ pulley now as it is modified by drilling the holes and also i noticed the cone shaped spacer that the damper slots over is cracked. Will using these parts again cause irreparable damage or vibrations? Or will it be irrelevant? P.s. rubber membrane is not damaged or drilled just outer metal ring. Cheers jj.

 

congratulations. if you need your harmonic balancer rebuilt, you might contact the following company:

So i take it the old one is now no good and needs replacing?

 

only running the engine will tell, I suspect the balance is lost, but if you have to remove it anyway to replace the cone spacer, you might as well have it checked and/or rebalanced by an expert.

 

Simply drill an equal hole on the exact opposite side to restore dynamic balance.

 

Actually that makes perfect sense, sometimes the simplest answer is the best. Thanks!
