Valve, Intake/Exhaust

NOTE:
Valve seat angle for inlet and exhaust valves: 45°
Recutting angle for inlet and exhaust valves: 60°





INLET VALVES
Width of inlet valve seat: 1 - 1.5 mm
Inlet valves face angle: 44,5°
Valve head diameter: 32 ± 0.1 mm

NOTE: The contact surface of the valve head has a 0.7 mm coating of stellite. Because the exhaust valve heads are stellited, only a very small amount of material should be removed on regrinding. Grinding using valve grinding (lapping) paste is the only recommended method. Consequently, if the valve is badly pitted, it should be replaced.





EXHAUST VALVES
Width of exhaust valve seat: 1.25 - 1.75 mm
Exhaust valves face angle: 44.5°
Valve head diameter: 29 ± 0.1 mm
