Gate Rotor and Support Clearance

When measuring, push the gate rotor against the pin to remove ﬂoat.

1.Place a straight edge along the side of the gate ro- tor, see Figure 5-16.

2.Measure the gap from the straight edge to the peak of the gate rotor support. For minimum distance, see Figure 5-15.

3.Repeat steps 1 to 2 to check gap along entire gate rotor edge on both sides.
