Hello all, since my 100/6 is history and I don't expect to have another one I've decided to unload some parts on ebay. The trouble is I'm not absolutely sure what I have left.

Specifically, I have two water pump pulleys and cannot identify them. Both are approx 2 5/8 deep and each is for the same size belt (3/8 I believe), but one is about 4 7/16 OD and the other is 5 1/8 OD. I suspect they are interchangeable but are probably year/model specific.

I see a whole collection of pulleys in the Moss cat. but no sizes. They both resemble Pt 61 in the Moss illustration. In fact I don't know if these are bolt on or press on but both have a key way on their inner dia where the shaft comes through. Any help is appreciated. Bob
 
Hi Bob,

I'm just doing my water pump now and the pulley is 5 1/8" OD. I think if there is a keyway it will be a bolt-together type.

Andy.
 
Hi thanks for part of the answer. Perhaps the smaller dia. pully is for the 3 liter engines. A smaller pully would turn a little faster and possible promote better cooling for the bigger engines.

Anyone with a better explanation please chime in. bob
