APRON WORM DRIVE CHAIN
The main apron drive chain is kept tight with a roller type
adjustable tightener. Periodically check tension on chain.
Chain is properly adjusted when there is 1/8”
deflection in center of chain. Also check tightener for
wear and replace when necessary. Failure to maintain
proper tension will result in excessive wear to the chain
and sprocket.
ADJUSTMENTS
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 has no sag between the rear
drive sprockets and chain slides under spreader.
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.
ADJUSTING
BOLT
WHEEL HUBS
To adjust wheel hubs, tighten the castellated nut on the
spindle to the point where there is no end-play and a
slight drag on the bearings. Replace the cotter key with
a new one of the correct size.
