## 🔌 Function

Takes the axial thrust from the rotating part bearing against it, carrying that load on a flat face so it is not passed into components that cannot accept it.

## ⚠️ Common Signs of Failure

-   Axial play or end float felt in the assembly
-   Knock or thump when thrust reverses
-   Thrust face worn bright, scored or stepped
-   Ring blued or discoloured from running hot
-   Debris or bronze-coloured dust in the oil

## 🛠️ Service Notes

-   3858457 and 3858458 share weight, fitment and name, so the published information does not separate them - order by part number and note that the earlier naming places this one at the rear
-   Check the mating thrust face for matching wear and renew both rings if either is marked
-   Measure end float on assembly rather than assuming the new ring restores it
