indicates bottom dead centre position of the pump) . • Reset the dial indicator to 0 (record the pre-load value) . • Rotate the crankshaft
in the CW direction to position the engine at TDC, set the gap. • Gently tip the pump until the dial indicator displays the timing value
(plus the preload value recorded above) • Tighten the pump attachment bolts • Remove the TDC gap setting tool. • Check.
Checking (3-1)
• Rotate the crankshaft 45° in the CCW direction and then rotate in the CW direction to position the engine at TDC set the gap.
• In this position, the dial indicator should indicate the timing value. • If necessary, repeat the timing procedure.
