VALVES & SEATS-INTAKE/EXHAUST

DESCRIPTION

The valves are made of heat resistant steel. They have nitrided stems to prevent scuffing. Viton rubber valve stem seals are integral with the spring seats. The valves have a single bead lock keepers to retain the springs.

OPERATION

The four valves per cylinder (two intake and two exhaust) are opened by using direct acting tappets which are actuated by the camshaft.

CLEANING

Clean all valves thoroughly and discard burned, warped and cracked valves.

CAUTION: Due to the small margin on the valves, grinding is not recommended.
