If timing is not within specifications, rotate engine to
correct crankshaft position (specified degrees before top
dead center) before removing injection pump. If
necessary to rotate engine in opposite direction of
normal rotation to achieve specified timing, rotate engine
to 90 degrees before top dead center and then rotate
engine to specified timing. This procedure takes up gear
backlash.
