## 🔌 Function

Sits under the hydraulic-pump drive retaining nut and gives it a hardened, flat bearing surface to tighten against, so the clamp load is applied evenly and the softer face beneath is not chewed up as the nut is torqued.

## ⚠️ Common Signs of Failure

-   Retaining nut found loose at service
-   Washer dished, cupped or no longer flat
-   Scoring or a bright polished ring on one face where the nut has been turning against it
-   Bruised or picked-up surface on the component beneath the washer
-   Cracking from the bore, or a washer that has split in two

## 🛠️ Service Notes

-   Confirm thread, length, grade and any single-use restriction against the exact application
-   Clean the threads and use the specified torque, angle and locking method
