4.2 INCREMENTAL WEIGHT PIN IS LOOSE OR FEELS SLOPPY
Possible causes
1) The snap ring holding the incremental weight pin in position is damaged or missing.
2) The incremental weight pin is damaged.
Solution
1) Remove the weight stack covers.
a. Remove the 4 screws holding the clear plastic cover over the incremental weight pin and
remove the clear plastic cover.
b. Check the incremental weight pin for damage, replace if needed.(1000398254)
2) Check if the snap ring and washer holding the incremental weight pin to the stack is in place
(Fig. A & B).
a. If this snap ring is missing, install a new snap ring.(1000102910)
b. If the snap ring is in place, but not holding the incremental weight pin in place, it may not be
properly installed in the groove in the pin.
c. If the snap ring is in place and properly installed in the groove, but the pin is still loose, replace
the snap ring (the ring may be too stretched out to be affective).
