Re: [Amc-list] stupid water pumps (195.6 water pumps)

[farna@xxxxxxx]

The problem is suppliers consolidating parts books and assuming there are just minor variations in some parts. 57-65 195.6 OHV and L-head engines all use a water pump in the front of the block, so some suppliers assumed they are the same. Early models used four bolts to hold the pump to the block (57-60?? I seem to recall my 61 had five bolts, but that was 25 years ago...), later models used five. Classics have a long pump shaft, Americans have a very short one. There are at least two different heater outlet arrangements, one to the left of the thermostat housing and one to the right. I believe my 63 American used one to the right -- I can't tell by the TSMs which setup used which outlet. It appears that 1V carbs used the outlet to the left, 2V to the right, but there isn't enough photos or other info to make any determination in the TSMs. I just remember getting a pump with the outlet on the opposite side to what I needed. It looked right excpet for that, but it's possible i
 t was 
a 199 pump. I never tried it on the car, looked at it in the store and knew it wasn't right. 
2 bolt patterns
2 pump shaft lengths (for each pattern)
2 heater outlets (for each of the above)
Eight different combinations?

Hey Frank, you mentioned waterpump compatibility/availability
with 195.6OHV water pumps -- where are the differences? Is it
all shaft length issues, eg. will any pump bolt in and operate,
other than the shaft? Or are there casting/depth/impeller issues?

(Just planning ahead, I will packrat parts if I can make
things fit.)
