CAUTION
When tightening each adjustment screw (C), ensure
that the bottom of the screw is aligned with the
valve stem (D). If the adjustment screw is not
aligned with the stem when tightened, it can cause
the stem to bend.
• Rotate the crankshaft clockwise slowly until the
number one (1) index (D) on the alignment rotor is
aligned with the flexible pointer.
• Rotate the crankshaft clockwise (viewed from the
front of the engine) two complete turns to ensure
that the flexible pointer and the alignment rotor
are aligned when the number one (1) piston is at
TDC.
• Use Tool MOT 647 to perform adjustments. (.
