21189181 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine 0.25 mm calibration shim used when setting injection-pump position and timing on the Volvo Penta D1-13F marine diesel engine.

🚤 Compatibility

Typically suits:

• Volvo Penta D1-13
• Volvo Penta D1-13B
• Volvo Penta D1-13F

• Engine Family: D
• HP Range: 13 HP

⚙️ Key Features

• Confirmed D1-13F application
• Nominal thickness: 0.25 mm
• Injection-pump calibration component
• Factory-controlled thickness
• Must be selected using the service timing procedure
• TH=0.25mm (Volvo assembly listing)

🔌 Function

The shim changes the injection-pump installed height to set fuel-injection timing accurately.

⚠️ Common Signs of Failure

• Hard starting, or the engine needing excessive cranking, when timing has drifted
• Black or white smoke and poor running after injection-pump work
• Fuel consumption or power noticeably off after a pump has been refitted
• Shim damaged, dished or picked up on its faces
• Fretting or an oil leak at the pump mounting joint found on strip-down

🛠️ Service Notes

• Select the shim from the measured timing procedure rather than reusing the thickness that came off
• This is the 0.25 mm shim, and 21189182 is the 0.35 mm thickness for the same D1-13F application
