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).
APRON
1. Adjust the apron by loosening the mounting bolts on
the chain slides on the outside of the frame. Mounting
bolts shown in the drawing.
2. Tighten the adjusting bolts until the apron chain clears
the underside of the axle by 1 inch.
3. Retighten jam nut.
NOTE: Tighten the adjusting bolts (on each front corner) equally on each side so that the apron slats run
parallel with the ends of the bed. The apron will be damaged if the machine is operated with one end of
the apron slats running ahead of the opposite end. Do not tighten the apron chains excessively.
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.
