Servicing The Tracks - Toro 2226 Operator's Manual

Servicing the Tracks

Service Interval: Before each use or daily—Check
the track tension.
WARNING
If you remove the track-tension grease valve
found in the hydraulic-track tensioner or
loosen it too much, grease can be released
and may cause serious injury or death.
Grease in the hydraulic track is highly
pressurized; ensure that the track-tension
grease valve is not loosened more than 1
revolution at a time.
Tightening the Track Tension
If the track seems loose, tighten the track tension as
follows:
1. Move the machine to a level surface and raise
the thrust frame and stabilizers so that the tracks
are raised.
2. Shut off the engine and remove the key.
3. Remove dirt and debris found around the
track-tension grease valve
Important:
Ensure that the area surrounding
the track-tension grease valve is clean before
beginning to adjust the track tension.
4. Remove the retaining bolts and cover that house
the track-tension grease valve.
5. Apply grease to the fitting until the tension
reaches 22,063 kPa (3,200 psi) as shown in
Figure 103.

6. Remove excess grease from around the valve.
7. Install the cover and retaining bolts.
8. Repeat steps 3 through
tension on the other side.

Loosening the Track Tension
If the track seems tight, loosen the track tension as
follows:
1. Move the machine to a level surface and raise
the thrust frame and stabilizers so that the tracks
are raised.
2. Shut off the engine and remove the key.
3. Remove dirt and debris found around the
track-tension grease valve
Important:
Ensure that the entire area
surrounding the track-tension grease valve
is clean before beginning to adjust the track
tension.
4. Remove the retaining bolts and cover that house
the track-tension grease valve.
5. Turn the track-tension grease valve
counterclockwise no more than 1 revolution
(Figure 103).
Note:
A 1-revolution turn releases grease and
loosens the track.
6. When the tension reaches 3,200 psi, turn the
track-tension grease valve clockwise to tighten
it.
7. Remove excess grease from around the valve.
8. Install the cover and retaining bolts.
9. Repeat steps
tension on the other side.
