2. Use the bucket and dozer blade to lift the unit up
until tracks are just clear of the ground as shown in
Figure 4-24.
3. Shut off the engine. Remove the ignition key and
take it with you. Lock-out the controls by raising
left control console.
4. Measure the clearance at the raised track roller
from the drive gear. Deflection should be between
3/4”-1” (20-25 mm).
5. Using a grease gun, pump grease into the fitting
until the track is properly tensioned (Figure 4-24).
