How to equalise bridge pieces
1 Rotate the engine to the position given in "Bridge piece and valve clearance setting sequence" on page 52.
Caution: Check the inlet and exhaust rockers have clearance on the bridge piece.
2 Loosen the locknut (A1) on the bridge piece.
3 Screw the adjuster (A2) out until the fixed side of the bridge piece rests on its valve.
4 Hold the top edge of the bridge piece and screw the adjuster down until it touches the valve.
5 Tighten the locknut to a torque of 35 Nm (25 lbf ft) without moving the adjuster.
