Re: [Amc-list] 195.6 water pumps

[Frank Swygert <farna@xxxxxxx>]

I believe the 64-65 American also uses the short shaft pump like the 58-63, but not 100% sure. All the big cars used the long shaft pump. Remember, the 56-64 big cars used the 195.6 also. 

The only problem with the bent neck (water heater connection) is it doesn't list the shaft length. As I recall at least one of my Americans used the bent neck, bent at maybe a 30 degree angle. 

Do the aluminum engine pumps have four mounting bolts instead of five? I know I was sent a four bolt pump by mistake once. I thought it was for an early 195.6 (56-57 OHV), but it could have been for the AL engine. 

If you decided to press the hub on further and shorten the shaft, make sure you press on the back of the SHAFT, NOT THE IMPELLER! The cast metal impeller won't take much stress at all (it was a long time ago, before I knew better!!).

If rockauto's photos are correct, they have most of the pump
variants available (Cardone rebuilds only though).

I detect five water pump variants:

* Cast iron, straight neck (see below), short shaft (Cardone #58270)
* Cast iron, straight neck (see below), long shaft (Cardone #58269)
* Cast iron, bent neck (Cardone #58268)
* Aluminum, for the aluminum motor (Cardone #58272)
* Cast iron, for the aluminum motor (Cardone #58278)

Maybe the bent-neck one is the L-head? Dunno. The bent neck is
real obvious.

The SHORT SHAFT motor I think is for the Nash-based Americans
(it's specified for the 63 01), and the LONG-SHAFT for 64-up AMC
American. Probably the pulley flange could be pressed further
down the shaft on a press, to use a newer (64-up) pump in the
older motor, but I ain't doing that.
