21193261 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine 0.25 mm calibration shim used to set injection-pump position and fuel timing on the Volvo Penta D2-40F marine diesel engine.

🚤 Compatibility

Typically suits:

• Volvo Penta D2-40
• Volvo Penta D2-40B
• Volvo Penta D2-40F

• Engine Family: D
• HP Range: 40 HP

⚙️ Key Features

• Confirmed D2-40F application
• Nominal thickness: 0.25 mm
• Precision injection-pump calibration shim
• Controls pump installed height
• Selected from the injection-timing measurement
• TH=0.25mm (Volvo assembly listing)

🔌 Function

The shim adjusts the injection-pump installed height and therefore the beginning of fuel injection.

⚠️ Common Signs of Failure

• Difficult starting or rough running after injection-pump work
• Smoke and fuel consumption changed from normal
• Measured injection timing outside the specified value
• Shim dished or picked up where it has been clamped
• Fuel or oil seep at the injection-pump mounting joint found on strip-down

🛠️ Service Notes

• This is the 0.25 mm shim, with 21193262 covering the 0.35 mm thickness for the same D2-40F application
• Select the thickness from the measured timing procedure, not from the shim that came out
