ADJUSTMENTS
BEATER CLUTCH ADJUSTMENT
It may be necessary to compensate for wear in the beater clutch and clutch control yoke. When properly
adjusted the moveable jaw clutch should have one-quarter (1/4”) inch (distance C) between clutches
when disengaged. To adjust, loosen jam nut (A) holding spring bracket. With beater disengaged (clean
out position), tighten nut (B) against shifter lever bracket until the proper distance between clutch jaws is
reached. Overtightening will cause beater not to fully engage and cause excess tension on cable. Tighten
lock nut (D) so there is one thirty-second (1/32”) inch clearance between clutch jaws (E).
TWO SPEED CLUTCH
If clutch control yoke becomes worn, it may be necessary to adjust the high speed clutch so it engages
and disengages completely. Adjustment to compensate for this wear is made by sliding spring stop (A) on
the control rod closer to the clutch engaging lever. Initial adjustment should be made as follows: Distance
between the washers on each end of the spring is 5-1/2”.
There should not be any space
between the jam nut and shifting
rod bracket. If there is, adjust
the turnbuckle at the front of the
spreader.

APRON WORM DRIVE CHAIN
The apron worm drive chains are kept tight with
a spring type tightener that does not require
adjustment. However, periodic inspection
should be made to check for wear.
