Crank Pulley / Harmonic Balancer Weight

[Mark T]

Hi! The crank pulley / harmonic balancer that was on my 2.8 when I bought the car was cracked so I bought another one (Thanks Sam!). The original one weighed 4.5 lbs but the new one weighs almost 8 lbs. Does it make any difference? I could lighten it by having the outside groove machined off, but I have enough clearance with the cross member that I don't have to. Thanks!

Mark,

I would suggest machining it off, not just for lightening, but for aesthetics too. Even though you have room for it, it just looks better without it just sitting there empty.

Thanks Jose!

But what's Mark going to do when he adds the A/C?

If we keep getting heat like this I may seriously consider it! (Not really... would draw too much power!) I had the top down on the Sebring this morning and I had the air on full blast to make it bearable.

Just noticed that the new pulley, which is from the 2.9 engine, is about 1/4" larger in diameter than the old 2.8 pulley. Will that make any difference?

I suggest drilling a couple of holes through the floor pans and filling the car with ice before setting out for Dayton! Good luck, Mark. Dwain Cooke came by for a great visit today, sharing all kinds of things with me that will eventually be helpful--first SAOCA member I've met face to face. I don't know for sure, but I doubt if that slight difference in diameter will be crucial.
