Loosening the Track Tension
If the track seems tight, loosen the track tension as follows:
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Remove dirt and debris found around the track-tension
grease valve (Figure
Important: Ensure that the entire area
surrounding the track-tension grease valve is clean
before beginning to adjust the track tension.
3. Remove the retaining bolts and the cover that house
the track-tension grease valve.
4. Turn the track-tension grease valve counterclockwise
no more than 1 revolution
Note: A 1-revolution turn will release grease and

5. When the tension reaches 31,026 kPa (4,500 psi), turn
the track-tension grease valve clockwise to tighten it.
6. Remove excess grease from around the valve.
7. Install the cover and retaining bolts.
