🔧 Product Description
Internal hydraulic pump piston used when servicing a Volvo Penta steering helm-pump assembly. Part number 22275105 is a component-level piston for the large-displacement/internal service position; it is not the complete helm pump.
⚙️ Key Features
- Internal steering-pump service component
- Precision hydraulic sealing surface
- Matched to the original pump bore
- Requires clean steering fluid and controlled assembly
- Pump model must be identified before ordering
- Engine type: Marine hydraulic steering system
🔌 Function
Reciprocates within the helm pump to displace hydraulic fluid as the steering wheel turns.
⚠️ Common Signs of Failure
- Scored piston surface
- Internal pressure loss
- Heavy or inconsistent steering
- Contaminated hydraulic fluid
- Pump cannot hold pressure
🛠️ Service Notes
- This is the large-displacement piston of a matched small/large pair - its counterpart 22275104 is the small-displacement version, well under a third of this piston's weight; do not substitute between the two even though both share the same pump family
