## ⚙️ Key Features

-   Oil-resistant sealing lip
-   Correct shaft and housing dimensions
-   Replaces earlier seal 20412568
-   Maintains oil-pump housing sealing
-   Suitable for continuous engine-oil temperature

## 🔌 Function

The seal prevents lubricating oil from escaping around the rotating oil-pump shaft or housing interface.

## ⚠️ Common Signs of Failure

-   Oil leakage at the pump housing
-   Hardened or torn sealing lip
-   Groove worn in the shaft
-   Seal displaced from the bore
-   Low oil level caused by external leakage

## 🛠️ Service Notes

-   Note which way round the old seal sits before you pull it out; a lip seal only holds one way and fitting it reversed guarantees a leak
-   Check the shaft or wear sleeve the seal runs on — a groove worn by the old seal, or any burr, nick or rust in the running band, will cut a new seal straight away
-   Clean the housing bore, then press the seal in square using a drift or tool that bears on the outer face of the seal, never on the lip, and take it to the depth the original sat at
-   Lightly oil or grease the lip and the shaft before assembly so the seal is not run dry on start-up, and keep grit away from the lip
-   Sleeve or tape over splines, keyways, threads and step edges when passing the seal over them, and never lever the lip past an edge with a screwdriver
