UNDERCARRIAGE
Fig. 5.53. Track Adjuster
1. Track Adjuster Cover
2. Relief Valve
3. Lubrication Fitting (Ball Check Valve)
4. If lubricant still does not appear, use the following emergency method. Should the relief
passages still be blocked, unscrew the ball check and/or relief valve an additional 1 to 2 turns
(2 ½ total turns).
WARNING! Use extreme care when relieving pressure with the following
emergency method. If loosened excessively, the cylinder pressure can eject the
ball check or relief valve. NEVER loosen these parts more than a total of 2 ½
turns.
5. When the proper tension has been obtained, tighten the ball check and/or relief valve to
61 – 75 [Nm]. Install the cover and secure with the removed hardware.
IMPORTANT: Never remove one link to bring a stretched track to within the range of proper track
adjustment. A track that is worn badly enough to take up the length of one link, will be so far out of
pitch that the increased wear on the sprocket will far more than offset the saving obtained by the
removal of one link in the track chain.
5.19.6. TRACK FRAME GUIDE
To avoid excessive wear of undercarriage components and track frame suspension points, the
track frame guide must be checked periodically.
Measure clearances "A" and "B". If the total is 6.5 [mm] or more, adjust by removing shims (4)
from between spacer blocks (5) and inner wear plate (2). Remove enough shims to reduce the
total clearance (A+B) to 0.8 [mm]. Keep the removed shims for future use.
If the removal of all shims (4) will not provide a total clearance of less than 6.5 [mm], replace wear
plates (1 and 2), worn guide plate (3), as required. Reinstall the shims and repeat the check.
Lubricate track frame guides. Apply grease into clearance “A" and “B".
