AZFJ 09-04-2002, 11:47 AM ..I did a search for a pump pully...Said..look for Ford pully off a big block!...Well..I found one..It has a wider pully groove to match the belt ..( Kind of )...But the hole is too small to fit on the pump shaft!...The quistion..Any one else have this promblem?...what did you do?..Is it ok to have the pully machined to fit the shaft?...It presses on...Scares me a bit!! wngrog 09-04-2002, 12:09 PM Just run the wide belt on the narrow pulley! It works fine....belts are designed to run on the edge so a thicker belt will work on a narrow pulley when a narrow belt won't work on a wide pulley. This is the way I ran mine for YEARS! Pin Head 09-04-2002, 12:16 PM On a Saginaw pump? Or run a narrow belt on the wide pully. I have been doing that for years too. The rumor is that 4 popper Jeeps and 70s Volvos used the wide belt pulley on Saginaw pumps. AZFJ 09-04-2002, 12:30 PM ..Thanks!!...I will try that!!.. wngrog 09-04-2002, 12:49 PM The problem with a narrow belt on a wide pulley is that is runs in the valley of the pulley and it will slip under heavy load. I used to have a hell of a time with my p/s when a guy pointed out that the valley of my pulley was polished, meaning the belt was slipping. I moved up to a wider belt that just contacted on the sides and it never slipped again. fc187 09-04-2002, 01:07 PM Originally posted by wngrog The problem with a narrow belt on a wide pulley is that is runs in the valley of the pulley and it will slip under heavy load.

I haven't noticed that problem with the narrow (17/32") belt driving my PS pump, York and 2 alternators, but my Gates Gator Grip belt does not bottom out in the crank pulley groove. wngrog 09-04-2002, 03:17 PM Originally posted by Pin Head .....but my Gates Gator Grip belt does not bottom out in the crank pulley groove. That's the key....
