## 🔌 Function

Encloses the timing gear train at the front of the engine, keeping it oil-tight and carrying the front crankshaft seal and drive mountings.

## ⚠️ Common Signs of Failure

-   Oil seeping from the front of the engine and collecting on the crossmember
-   Wet front pulley or oil thrown along the belt run
-   Cracks around the mounting bosses or the seal housing
-   Distorted or scored gasket face after a previous repair
-   Seal bore worn oval so a new seal still weeps

## 🛠️ Service Notes

-   At 19.1 kg this is a heavy, awkward casing to handle and needs support while the fasteners are started
-   Fit a new front crankshaft seal and a full gasket set with the casing, and check the seal bore and pulley hub for wear before assembling
-   Clean all sealant from the block face so the new casing pulls down square
