There are 3 different water pumps used on Studes V8 Standard, heavy duty, and
Avanti. The difference is on a standard pump you can see about 1/2" of shaft
between pump housing and flange, it also has a 1.060" nose.On a heavy duty
pump there is almost no shaft showing and the boss for bearing on water pump
is larger and comes out to meet the flange. This pump is used on air
conditioned models, The avanti pump is the same as the heavy duty, but it has
3 gussets that come down from the main body of the pump to the boss on the
bearing housing and the nose should be 1.054".You should try to use nothing on
an Avanti, but a Avanti pump because of the weight of the water pully. Casting
No. on the Avanti pump is #1560400. Casting no. on heavy duty with long
bearing boss is #527070. Casting no. on standard pump is #1554634. McQuay
Norris has a pump #PC269 that you may be able to get at your nearest FLAPS.
