record the distance between the inner lift pivots and
the inner rod pivots. Repeat for other side of unit.
See Figure 35.
3. To check the outer lift rod timing, measure and
record the distance between the outer lift pivots and
the outer rod pivots. Repeat for other side of unit.
See Figure 35.
4. If the measurements for the inner rods are equal,
and the measurements for the outer rods are equal,
no further adjustment is required. If the measure-
ments are NOT equal (greater than 1/8" (3,17mm)
