## 🔌 Function

The thrust washer sits at the crankshaft thrust bearing and limits axial (fore-and-aft) movement of the crankshaft while providing a bearing surface for thrust loads. Correct washer thickness and condition maintain the crankshaft end float within specification.

## ⚠️ Common Signs of Failure

-   Excessive crankshaft end float measured at overhaul
-   Scoring, scuffing or wear ridges on the washer bearing face
-   Loss of the bearing surface layer exposing the backing material
-   Metal debris or bearing material found in the oil or filter
-   Knocking or thrust-related noise under load or gear engagement

## 🛠️ Service Notes

-   Measure crankshaft end float with a dial gauge before and after fitting to confirm it is within the engine's specification.
-   This is the inner half of a paired thrust washer — measure end float with the corresponding outer washer fitted, not in isolation.
