Stellar 109659 Parker VOAC F1-61 Hydraulic Piston Pump Kit

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar 109659 Hydraulic Pump Kit is a genuine OEM truck-hydraulic pump package featuring a Parker VOAC F1-61 fixed-displacement piston pump and a 1.25-inch fitting. The F1-61 bent-axis pump is designed for demanding mobile-hydraulic applications requiring high flow and pressure.

If the existing pump produces insufficient hydraulic flow, leaks, overheats, or creates excessive noise, the Stellar 109659 may be the correct OEM replacement. Replacing a worn pump restores hydraulic power for compatible Stellar truck-mounted equipment.

What This Part Is Used For

The Stellar 109659 pump kit converts mechanical PTO power into hydraulic flow. It supplies pressurized oil to compatible truck-mounted cranes, service equipment, and other mobile-hydraulic systems.

Common Reasons For Replacement:

Hydraulic equipment operates slowly
Pump does not produce adequate flow or pressure
Hydraulic fluid leaking from the pump
Excessive pump noise or vibration
Pump overheats during operation
Damaged input shaft or mounting flange
Internal piston or bearing wear
