TRACK MAINTENANCE

Before attempting to complete any of the three
parts of this Track Maintenance section, it is
recommended that you read all three parts
completely to provide background on how the total
Track System is adjusted and maintained.
Below are a series of drawings to aid you in
parts identification as you follow the procedures
described below. To aid clarity, only the parts
described in the instructions are included in most
of the drawings. In some cases, to lessen
confusion, certain parts (such as Track Rods), do
not appear in all drawings.
Consult the part photos and drawings at
the back of tractor manual to assist in
this procedure. (Refer to Part Drawing
MH-B and Part Photos MH-12, 13, 14,
17, 20, 21, 22 and 23).
NOTE: When working with the Tracks, you
will be dealing with some significant weights and
will be required to hold some specific alignments.
Though the Tracks can be successfully put on
(and off) by a single person, it's strongly advised
to have an able-bodied "helper" available both for
assistance and safety reasons!
TRACK REMOVAL
Drive your Crawler onto a firm, level surface.
Shut off engine and dismount. From below, block
Crawler so that Tracks clear the ground by 2".
Use solid blocking and place it under the Crawler
so that it will give the Tractor the greatest support
left to right and front to rear. When placing your
blocking, analyze the total weight and balance of
the Crawler as it will change as the Track is added
and removed!
