Engine pulleys

Thanks jfa!

Did message Cliff.

You are definitely correct about H-Town!!

Today it is BOILING!!!

Is having the larger fuel pump OK?

Also, do you put ATF or 20W in your carb dampers?  Mine is low and cannot tell if ATF or oil.  Doesn’t smell like oil?

Thanks,  Tom

That's your A/C compressor mounted on the left side of the engine. No belt could mean someone was having problems with it and just removed the belt rather than fix the problem... Also, no need for a "3rd pulley" in that system. You only need two belts - one for the A/C, one for the water pump and alternator.  Edit: Finally saw the smog pump and that you have all the pulleys you need. Nice looking aftermarket A/C install.

The compressor pulley should spin freely as it sits with no belt and while the compressor clutch is not engaged. You could turn the compressor clockwise using a wrench on the nut on the face of the pulley assembly (it holds the clutch plate onto the compressor shaft).

That's quite a hefty bill to maintain the old York and R12 system.  Newer system would have cost about the same.  Owner must have wanted to keep it period correct.

Dennis-I agree, that is HUGE MONEY back then, heck it is big money now!!

Still, why do you think they moved the compressor?  What did they gain?  They could of just exchanged the compressors. They had all the original Freon lines on the correct dealer installed side.

thanks,  Tom

I suspect they were lacking the boat anchor original mount or they wanted to mount it in such a way as to not interfere with the fuel pump. Your current install is much better in a number of ways

I guess there were a couple of install options that different dealers used for installing A/C. My series I car had the dealer York compressor installed on the same side as Tom's. I removed the York and installed a Sanden down where the air pump used to be (haven't completed putting it back together yet though). When I did the 3 row radiator with electric fans it wouldn't fit with the York so I had to remove it and go with the low Sanden mount.

It looks like the mystery of the pulleys is solved with Tom's additional pics and  @w3wilkes pics of an similar compressor install.  I think the theory of moving the compressor is pretty accurate as it allowed for future maintenance of the fuel pump.

Tom - as to your question to me on the carbs damper fluid, I've previously used ATF but currently use 3-in-1 oil with carbs rebuilt by Z Therapy.  It has a light viscosity and is easy to install with the small can and nozzle - so little is required that it didn't make sense to me to buy a typical quart container of something else.
