Servicing the Tracks

Cleaning the Tracks
Service Interval: Before each use or daily
Check the tracks for excessive wear and clean them
periodically. If the tracks are worn, replace them.
1. Lower the boom and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Using a water hose or pressure washer, remove dirt
from each track system.
Important: Ensure that you use high-pressure water to
wash only the track area. Do not use a high-pressure
washer to clean the rest of the machine. High-pressure
washing can damage the electrical system and hydraulic
valves or deplete grease.
Important: Ensure that you fully clean the road wheels
and the drive sprocket (Figure

Checking and Adjusting the Track
Tension
Service Interval: After the first 50 hours
Every 100 hours
To check the tension of each track, place 20.4 kg (45 lb) on
the track midway between the front road wheel and the drive
sprocket. The track should flex no more than 0.6 to 1 cm
(1/4 to 3/8 inch). If it does, adjust the track tension using
the following procedure:
46).
3. Track
1. Stop the machine in on a level surface and set the
parking brake.
2. Stop the engine, lower the boom, remove the key, and
wait for all moving parts to stop before leaving the
operating position.
3. Loosen the jam nut on the track tensioning bolt and
the clamp bolts on the tension arm
1. Tensioning bolt
2. Jam nut
4. Torque the tensioning bolt to 32.5 to 40 N-m (24 to 30
ft-lb) to tighten the track
5. Ensure that the track deflects less than 0.6 to 1 cm (1/4
to 3/8 inch) when 20.6 kg (45 lb) of force is applied to
the track span. Adjust the torque on the tensioning
bolt as needed.
6. Tighten the jam nut.
7. Tighten the clamp bolts and torque to 102 N-m (75
ft-lb).
Replacing the Tracks
When the tracks are badly worn, replace them.
1. Lower the boom and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
