3.15.2 Substitution
DANGER: Never work with the machine raised on a jack or
suspended, ra- ther always place it upon suitable trestles that can
maintain the weight of the machine before starting work.
For the substitution of the tracks, pro-
ceed as follows:
• Raise the side of the machine on which
you wish to work using hydraulic
jacks or a crane;
• Position the machine on suitable
trestles, and check to see that it is
stable;
• Take off the cover “B” by unscrewing
• the screws “A”;
• Using two wrenches, loosen the
fig. 35 - Replacing rubber tracks
counter-nut “C” and completely unscrew both the counter-nut and nut “D”;
• Take off the track “E” starting from the “Z” part;
• Mount the new track lining it up with the teeth in the drive wheel “F”;
• Fit in the “Z” part of the track onto the neutral wheel “G”;
• Register the tension by working on nut “D”;
• Check that the arrow is at 20mm;
• When the registering is done, block the counter-nut “C”;
• Put the cover back on.
To always achieve perfect operation of the tracks and of the machine, follow the
instructions on the label that precedes this description, the same that is located
on the C85 undercarriage.
