How much pressure does a Saginaw pump have?
Saginaw Power Steering pumps normally put out 1200 psi, but that is too much for a Mustang II Rack and Pinion system and can lead to oversensitive steering. We recommend this 800 psi pressure reducing valve for all Mustang II Rack and Pinion Set ups.
What are the main differences in power steering pumps?
Any pump from a small block, big block— long or short waterpump—, and some six cylinders may be used with the correct V-8 power steering pump pulley. THE MAIN DIFFERENCES in the POWER STEERING PUMPS ARE AS FOLLOWS: 1. Pump pressure* 2. Shape of reservoir 3. Number of attachment points between pump and reservoir on back of unit 4.
How does a pressure relief valve work on a power steering system?
Power steering pumps have a built in spring-loaded pressure relief valve. This valve is designed to lower or stop hydraulic pump pressure when pressure reaches a preset value.
How big is the power steering pump reservoir?
POWER STEERING PUMP DIMENSION LATE MODEL PUMP RESERVOIR 1- 13/16“ center of pulley to face of pump 1987- 91 Chevy PU 2WD 8 cylinder (350) 5.7 Liter press-fit pulley metric O-ring fitting *G.M. Saginaw pump pressure 1000-1200 p.s.i., Mustang – Pinto Rack & Pinion 820-870 p.s.i.
What happens when a power steering valve is stuck?
In the event a valve is fully stuck, all power steering will be lost and the vehicle’s steering will act as if the engine is off. GM Saginaw pumps see this problem far more frequent than other manufactured pumps. These symptoms are observable with ALL and ANY pumps: old , new, or rebuilt.
What are the power steering pumps on a GM Saginaw?
Tuff Stuff Saginaw style power steering pumps feature all new components including reservoir and pump assembly, a billet style chrome cap and a new dipstick. Direct-fit and universal pumps are available. Pumps are rated at 1200 PSI @3 GPM to work with most gearbox systems.
What’s the pressure on a power steering pump?
8 cylinder (350) 5.7 Liter press-fit pulley metric O-ring fitting *G.M. Saginaw pump pressure 1000-1200 p.s.i., Mustang – Pinto Rack & Pinion 820-870 p.s.i. Saginaw pump pressure may be decreased with the use of a – Flow Valve Shim Kit part number 1001 available from us or Mullins Steering Gears/ Borgeson Universal company (860)-482-8283.
Do you need a flow restrictor for a steering pump?
Not only is this an easier adjustment, but it will have no adverse side effects to the life of the pump. A properly sized flow restrictor will make the pump compatible with the steering unit control valve requirements. This will give the driver the desired steering feel without compromising the steering system.
Can a shim kit reduce the pressure on a steering pump?
Unfortunately, this is a myth. Many believe that when a steering system feels over-assisted it means the system has too much pressure and the fix is to install a shim kit. Installing a shim kit will indeed reduce the pump’s pressure capacity.
