Topic: 64.5 P/S pump pulley dimensions

[midnite cruiser]

Shopping for this I have been asked the pulley diameter and offset.

Could someone out there measure theirs? This is a D code with both P/S and A/C

Remote reservoir or is it using the special brackets to sit lower to clear the compressor?

Did you look in this Forum's Library?

Looking through the library I see data on crankshaft and water pump pulleys only.

Convert has A/C and P/S with the remote silver top fender mount reservoir

Still would appreciate a member taking a quick tape measure on their Eaton pump pulley

I don't have my book handy, but would highly recommend picking up a copy for your reference library:

It has the info you're looking for and much more.

I have that book. Will keep digging.

Mine is a 260 with A/C and power steering, same unique compressor bracket with remote P/S reservoir. I’ll post some pics. My pulley is a different type, they were not all the same, the differences are listed in Bob Mannel’s book in the back. I’ll look up the info for the type bracket you have shown.

From looking at the pulley tables in Mannel’s book, appendix B-20, the power steering pulley that you show in the picture looks to be an A/C magnetic clutch matted to a York compressor. The three predominant manufacturers for 64-66 were Pitts, Warner, and Eaton. I can’t see the face of the pulley to make a positive ID, but it looks to be a Pitts magnetic clutch pulley, this was the primary clutch used in 1964.

The info is:

Part number: C4OZ-2884-A
ID number: C4OA-2981-A
Depth: 1.4
Diameter: 6.8

I think he is wanting the diameter of the power steering pulley not the AC clutch.  Mine is over 5 inches but is a different set up.

Sorry, moving too fast. Let me try again.

Ok, here is the power steering pully info. I measured mine and it’d 4 6/16 inches across. The book says the Eaton power steering pulley diameter for 64 is 4.4 inches, so that’s about right. The pics are attached.
