Wanted: balancer with ...
 

I'm looking for an Internet friend. He needs a 2 sheave balancer for a '63 389. He is putting the engine in a late 50s GMC truck and would like to run A/C. Any leads would be appreciated.

Bill,I might have a HD 2 sheave balancer I had rebuilt by the Damper DR.Tom

I do have one stock,looks good.Will post pics tomorrow.Tom

Thanks Tom.

I'm traveling tomorrow and Tuesday, so it may be Wednesday before I can respond to any messages. If OK with you, leave me a PM with either a phone number or an email address and I'll get him to contact you directly.

Does he also need the third pulley used to run the AC. I think I ended up with two of those and am not going to use but one. It fits into the 61-62 7 1/2-inch crank pulley but will not fit into the 61-62 7-inch non-AC crank pulley. So should fit into the 63 8 3/8-inch crank pulley. Might even fit into the 63 7 1/4-inch non-AC crank pulley. I can send dimensions if interested.

FWI,the 2 shive HD balancer can not have another belt attached to it!2 only.Tom

Bill,
I think this is the pulley pfilean is refering to. It's a cast aluminum pulley - casting # 149V201 and is mounted after the harmonic balancer. This is the pulley used on my 62 Catalina. I'm pretty sure this pulley was used from 61 - 64 full size Pontiacs.

T Weber is on the right track. Except mine is a rolled steel as you are accustomed to seeing on old Pontiacs. Mine is maybe not as deep as T Weber's but fits the same in the 2-groove pulley with the damper on last. I think mine I have marked as a 65 which I can believe as it bears a 9781741 part number. That doesn't show in the parts book as the parts book usually shows a number for the combined pulleys and damper and not each component number. I used a similar pulley when I added VA using a proper 61 bracket for a A6 compressor although I used a Sanden.

I don't know what Bill's friend has in mind. If a 63 2-groove works without over driving the compressor so much the better. Like people used to say, "there is more than one way to skin a cat". But why would you want to?

If this hasn't been resolved, I have about 100 pulleys from the '60's. Lemme know........
