17342619 Restricting Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta restricting washer is a structural mounting or fastening component used in the flywheel-housing lower-gear lubrication circuit. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it meters oil flow in the flywheel-housing lower-gear circuit to protect gears and bearings from starvation or uncontrolled flow. Selection must be confirmed by OEM part number 17342619, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1170-72VE

• Engine Family: TAD

⚙️ Key Features

• OEM Volvo Penta part number 17342619
• Calibrated flow-restricting component - do not substitute with a plain washer
• Net weight: 0.001 kg
• Fits TAD-series industrial diesel engines

🔌 Function

Meters oil flow in the flywheel-housing lower-gear circuit to protect gears and bearings from starvation or uncontrolled flow. Inspect threads and contact faces, replace one-time locking hardware where specified and tighten to the Volvo Penta torque and sequence for the exact assembly.

⚠️ Common Signs of Failure

• Flow or pressure measured outside specification in the affected circuit
• Orifice partially or fully blocked by debris
• Erosion or wear enlarging the orifice over time
• Distortion or damage from over-tightening
• Symptoms of over- or under-supply in the component being fed

🛠️ Service Notes

• Meters oil to the flywheel-housing lower-gear circuit on TAD1170-72VE only — a narrow, single-engine fitment, so do not assume it interchanges with restricting washers used elsewhere in the lubrication system
• At 0.001 kg this is a fine calibrated orifice washer; a plain washer of similar size will not meter flow correctly and can starve or flood the gear it feeds
