- Use a suitable lifting device in order to raise the machine until tracks (1) and Dimension (X) is approximately
50 mm (2.0 inch)off the ground. Position Tooling (A) under the machine. Illustration 2 g01390764
- Loosen jam nut (2) up to the stop. Loosen tensioner (3) up to stop. This will relieve the tension from the track.

- Remove bolts (4) and remove idler wheel (5).
Illustration 4 g01390800 Typical Example
- Reposition track (1) and attach two suitable lifting devices to track (1). The weight of track (1) is approximately
85 kg (189 lb). Use the suitable lifting devices in order to remove track (1) from the machine.
- Attach two suitable lifting devices to track (1). The weight of track (1) is approximately
85 kg (189 lb). Use the suitable lifting devices in order to position track (1) to the machine.
- Place suitable cribbing beneath track (1) in order to provide additional support. Remove the suitable lifting devices and finish positioning track (1) to the machine.
Note: Apply a soap and water solution to the surface of the front idler wheel and on the inside of track (1) in the front. This will help in positioning track (1).

- Place a
45 kg (100 lb)weight on the track between the drive sprocket and the idlers. Measure the track sag between the bottom of the straight edge and the top of the track. Turn tensioner (3) in order to tighten the track. The track sag should be set at 12 mm (0.48 inch).
- Tighten jam nut (2) to a torque of
270 ± 40 N·m (200 ± 30 lb ft).
