# 1542158 Waved Washer | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta waved spring washer used in the injector and heat-shield mounting stack on 30- and 40-series indirect-injection diesel engines. The part is installed at every injector position and must be assembled in the sequence shown in the engine fuel-system arrangement. Four are normally required for a complete 30-series engine and six for a complete 40-series engine. The heat shield, waved washer, injector washer and support washer are separate service parts and should not be interchanged.

## 🔌 Function

The washer seals or distributes clamping load at a fuel system connection or fastener, helping maintain a leak-free joint and correct bolt tension. Because it deforms in service, it is treated as a single-use item on reassembly.

## ⚠️ Common Signs of Failure

-   Fuel weeping or seepage around the joint it seals
-   Visible flattening, cracking or distortion of the washer
-   Fastener loosening or inability to hold correct torque
-   Corrosion, pitting or scoring on the sealing face
-   Air drawn into the fuel system causing hard starting or rough running

## 🛠️ Service Notes

-   This is a spring washer, not a flat one — once compressed in service it has taken a set, so renew it every time the injector stack is disturbed rather than reusing it, even if it looks undistorted.
-   It sits in the same stack as the heat shield, injector washer and support washer at each injector position; keep the parts for each injector separated in the order removed so the stack goes back exactly as it came apart.
