PSC Remote Power Steering Reservoir Kit for Type II / TC Pumps
SR146-6-10
The PSC SR146 Remote Power Steering Reservoir Kit is designed for high-demand steering systems that require increased fluid capacity, improved cooling, and a steady gravity-fed supply to the power steering pump. It is well suited for hydro-assist steering, Hydro-Boost brake systems, full hydraulic steering, and other applications where heat, aeration, and pump starvation can reduce steering performance.
Precision TIG welded from aluminum, the PSC SR146 features a high-volume design and an internal 35-micron filter cartridge to help reduce contamination, cavitation, pump noise, and premature component wear. Designed for PSC Type II and Saginaw TC power steering pumps, this remote reservoir is available with multiple feed and return port configurations, with optional hose kits for a more complete installation.
Includes:
- (1) PSC SR146 Remote Power Steering Reservoir
- (1) Mounting Bracket
- Required Fittings Based on Selected Configuration
- PSC-Approved Hoses and Fittings with Hose Kit Option
Note: Included fittings and hoses vary by selected configuration.

Installation Notes:
- Mount the reservoir above the power steering pump to provide proper gravity feed.
- Select the feed and return port sizes that match the pump and steering system plumbing.
- Use PSC-approved hose sizes and fittings for best performance.
- Keep the pump feed hose as short and direct as practical.
- Avoid tight bends, restrictive fittings, and routing near excessive exhaust heat.
- Route return fluid to minimize turbulence and aeration inside the reservoir.
- Verify hood, suspension, steering shaft, and engine accessory clearance before final mounting.
- Flush the complete steering system before connecting the new reservoir and pump.
FAQ
Why use a high-capacity power steering reservoir?
Additional fluid capacity gives the system more time to release heat and separate trapped air before the fluid returns to the pump. This is especially important in vehicles that repeatedly cycle the steering under load, including rock crawlers, race vehicles, and rigs using Hydro-Boost brakes.
What does the internal 35-micron filter do?
The internal filter helps remove contaminants from the returning fluid before it reaches the pump. Cleaner fluid reduces wear on the pump, steering valve, orbital valve, steering gear, and hydraulic cylinder components.
How does reservoir placement affect pump performance?
A power steering pump relies on an unrestricted supply of fluid at its inlet. Mounting the reservoir above the pump creates a gravity-fed supply that helps prevent pump starvation, aeration, and cavitation during rapid steering input or sustained high-load operation.
What are the signs of power steering cavitation?
Common symptoms include pump whining, foamy fluid, inconsistent assist, steering chatter, overheating, and pressure loss. Cavitation can be caused by a restricted feed hose, low fluid level, poor reservoir placement, air leaks, or undersized plumbing.
Will this reservoir work with Hydro-Boost brakes?
Yes. The additional fluid capacity and filtered remote-mount design make the SR146 well suited for systems where the power steering pump supplies both steering assist and a Hydro-Boost brake unit, provided the pump, hose sizes, cooler, and return routing are properly matched.
Which port sizes should I select?
Select the feed and return sizes to match the power steering pump and the rest of the hydraulic system. The pump feed line should remain large and unrestricted, while the return line must be sized to handle system flow without creating excessive backpressure.
