I've got to pull the original harmonic balancer on a '98 Buick Regal GS with about 150k miles in order to install a new crankshaft position sensor.
I'm wondering if it would make sense to buy/install a new harmonic balancer while I'm at it. I've already installed all new accessories recently, along with tensioner and idler pulleys. Heck, I even replaced the A/C compressor with a delete kit just recently after it siezed and snapped the belt. So only the harmonic balancer is still old/original.
I looked on Rock Auto and was surprised to find out there are a few options. Normally for this I would go ahead and purchase a new ACDelco unit, but it looks like Dayco makes a couple different versions. It's hard to tell by the description if they under drive the accessories or overdrive the supercharger though.
I really don't want to under drive the accessories or overdrive the supercharger. I already have the ZZP modular pulley on the S/C snout and I would rather change that way.
Has anybody else seen or bought these Dayco harmonic balancers? One of them looks like it is made from billet aluminum. If it were a lot lighter than I would be interested...maybe.
