{Chrysler 300} Re: 1964 PS Pulley

They do make a 1" thermostat spacer you can install between the neck and the water pump housing that allows you to screw in a temperature sensor for EFI but it can be a little tight under that RV2 compressor. This would allow you to retain that housing if it helps with alignment. And yes the federal and trw pumps can be problematic if worn out, but relatively easy to reseal if you are careful when pressing the pulley back on ( with the reservoir removed of course).

I bought and installed a sanden bracket and went through this pulley nightmare myself to get it all to align. Got it to work with trial and error.

Good luck!

Thanks…I am sick and tired of the TRW pumps, and I am thinking of trying to use a brand-new Saginaw.  Borgeson makes on and uses a spacer between the bracket and the pump housing. I can make up new ones if need be, for alignment.

 

In the next month or so, I plan on tearing down the front of the engine (again, I just did it 2 years back) not because anything is wrong, but I need the later 1960’s water pump housing that has the second port for a temperature sender. I plan on EFI at some point, so it needs that. I am sticking with the RV2 A/C so getting everything to work is a little bit of a pain.

 

Best, James

About 3/4" difference in diameters. Assuming the Chrysler federal pump is used for either scenario. I have also found the pulley offset from the hub is slightly different too.

Anyone know off hand what the differences are in the pulley for the power steering pump on the A/C vs non-A/C cars?

 

Thanks, James
