🔌 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.
