BELT INSPECTION
The rubber track is composed of several layers of cable, similar to the cables used in automotive tires. The most
important set of cables are located about 8 mm (0.3 in.) beneath the inside surface of the track. This set of ca-
bles, called zero degree cables, withstands track tension. Other cables, called breaker cables, are located between
the zero degree cables and the outside surface of the track. These are laid in various angles to provide lateral
support and to protect the zero degree cables.
When any of the cables are exposed to moisture by cuts or gouges in the rubber, they can deteriorate by rusting.
Because of this, any exposed cables should be repaired as soon as possible. Any damaged zero degree cables that
protrude above the surface of the track should be clipped or ground down to below the surface of the track to
prevent additional damage due to unraveling. Cuts, gouges and minor wear on guideblocks are not expected to
cause operational problems. However, a track that has two or more consecutive guideblocks missing should be
replaced since this could lead to untracking, possibly damaging other undercarriage components.
STORAGE PREPARATION
IMPORTANT: When the track system is not going to be used for a length of time, store the tracks in a dry, pro-
tected place. Leaving your track system outside, open to the weather, will shorten its life. Park the track system
on level ground. Block the front and rear of the belts to prevent the tracks from rolling unexpectedly. Inspect
the track system and touch-up spots where the paint has been worn away (use a good quality primer paint).
REMOVING FROM STORAGE
1. Make sure the air spring pressure is inflated to 100 psi.
2. Inspect rubber belt for cuts or gouges and repair any damaged cables.
3. Check for missing or damaged guideblocks and replace as necessary.
4. Lubricate all grease points.
5. Repack the wheel bearings. Use Bearing Guard MK1 or equivalent lubricant.
6. Check the seal for wear and replace if necessary.
7. Check the wheel hubs and make sure the nuts are properly torque to 350 ft.-lbs.
When performing maintenance work, wear sturdy, rough-soled work shoes and protective equipment for eyes,
hair, hands, hearing and head. Follow Operator’s Manual instructions to ensure safe and proper maintenance
and repair.
Your local, authorized dealer can supply genuine replacement parts. Substitute parts may not meet original
equipment specifications and may be dangerous.
BE CERTAIN THAT ALL POWER IS SHUT OFF TO THE GRAIN CART BEFORE PERFORMING ANY
MAINTENANCE OR REPAIR WORK.
