A/C issues
Hi,
I just had work done on my ’65 A/C system. I trust the work, but I discovered that the replacement compressor clutch assembly has a shallower pulley on it than the original ’65 part – evidently a modernization of the brushes that the original used has narrowed the assembly. As a result, the belt that spins the compressor is about a quarter inch out of alignment with the other pulleys that share the belt. I dug around on the Internet and found some replacement brushes for the old ’65 part, but nothing in the way of a rebuilt or new manufacture clutch assembly that specifically details the pulley depth (or notes the old style brush assembly as a requirement). I kept the original part in the hopes that it could be rebuilt – but so far; no luck. Does anyone have a similar experience – or know of a source for the original part – or know of a replacement that matches the depth of the original pulley? So far the A/C is working (it required a shorter belt to eliminate the squeal caused by the original belt over a smaller pulley). but I’d like to return it to the factory set up.
Thanks

RE: A/C issues
Hi Amsoil,
I want to keep the car as original as possible - the original part functioned fine for about 40 years. The compressor is a solid mount on the top of the block with no wiggle room in the bracket; the pulley only has one notch.
Thanks

RE: A/C issues
can you simply place some spacers (5/16 washers) between the compressor and the block? You may need to get 1/4 longer bolts, but they are pretty standard and you should be able to get them at any auto parts store.
