new harmonic balancer

[dohc nut]

does anybody know who makes a balancer for the 3.4l dohc? Dorman says they do but you get one for 3.1 with belt track built in and no timing mark they offer no other number. please help thanks

rockauto doesn't list any. Just repair sleeves.

I'd start with a GM dealer, although I wouldn't have a lot of hope.

Rebuilding originals may be the only option.

Thanks for your reply. I did of course first check gm and its discontinued and none available. AC Delco shows a part number but shows a picture of the pulley which bolts to the balancer. But i was not at all aware that there were guys rebuilding these things. hopefully i can get one at the wrecker to time my engine and leave in until I get one rebuilt! thanks for the suggestion. I wonder if anybody is doing it up here in Toronto Canada?

alldata is showing(for a 95 monte carlo Z34):

that's the damper. the pulley is 24502908.

seems that 91-93 and 94-97 had different parts.

92 cutlass supreme 3.4:

10162070

and the pulley is 10127523.



all sources i checked are showing out of stock and discontinued on the later parts, but one has a listing for the 91-93:
