It is used on the heavier trucks. No reason not to use it. It looks like a good setup with the dual belts. The other is a smog pump. They say money can't buy happiness. It can buy old Chevy trucks though.

Will that pump work OK with the PS box from a 78 1/2 ton Chevy truck ? I robbed the front suspension, brakes, and steering from a 78 and have it mounted under the 53 frame. The reason I ask is that I have heard stories of mxing and matching PS pumps and mostly rack and pinions where the pressure is too high and blows out the seals. | | | | | Joined: Feb 2000 Posts: 769 Shop Shark | | Shop Shark Joined: Feb 2000 Posts: 769 | Another option is a 250 PS pump. I used one on a 292 years ago. It will require a small amount of modifing to work, but it was not much. From the looks of the pictures of the UPS setup, it would not fit in an AD anyway. That crank pully is sure deep. | | | | | Joined: Dec 2007 Posts: 96 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2007 Posts: 96 | I actually have a PS pump and brackets from a 250 that Tntrucknut gave to me when he came down to look at the modified front suspension. Stovebolters are the greatest folks on earth. You are right, it would take some modification, but can be made to work. | | |
