Valve: Service and Repair

INLET VALVES
^ Face angle: 44.5°
^ Valve-head diameter: 32 ±0.1 mm





EXHAUST VALVES
^ The contact surface of the valve head has a 0.7mm coating of stellite.
^ Face angle: 44.5°
^ Valve head diameter: 29 ±0.1 mm

NOTE: Because the exhaust valve heads are stellited, only a very small amount of material should be removed on regrinding. Consequently, if the valve is badly pitted, it should be replaced.
