# 20881359 Shim | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta 1.1 mm calibration shim for the unit-injection-pump/tappet installation used on the specified D5/D7 mechanically injected engines. The shim sets the installed height of the pump relative to the cam-driven tappet, making it a precision timing and plunger-stroke component rather than a general packing washer.

## 🚤 Compatibility

-   **Engine Family:** D, TD, TAD

## ⚙️ Key Features

-   Genuine Volvo Penta 1.1 mm Injection Pump Calibration Shim - part number 20881359
-   Precision thickness: 1.1 mm
-   Engine type: D5/D7-series mechanically injected industrial diesel engines
-   TH=1.1mm (Volvo assembly listing)

## 🔌 Function

Sets the installed height of the unit injection pump against its cam-driven tappet at 1.1 mm, so the plunger stroke and the timing of the injection event land on specification.

## ⚠️ Common Signs of Failure

-   Hard starting, smoke or rough running traced to one pump's timing
-   Injection timing found outside specification after a pump has been changed
-   Knock or harshness from one cylinder under load
-   Shim found pitted, brinelled or dished where the tappet bears
-   Measured shim thickness no longer matching the number stamped on the packet

## 🛠️ Service Notes

-   Supersedes 11700396
-   Shim thickness is chosen by measurement on the engine, so do not simply refit the thickness that came out
-   The family runs from 1.0 mm (20881345) to 3.7 mm (20881454) in 0.
