Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the
engine has been stopped. Serious injury can be caused if this pressure is
not released before any service is done on the hydraulic system.
Make sure all of the work tools have been lowered to the ground, and
the oil is cool before removing any components or lines. Remove the oil
filler cap only when the engine is stopped, and the filler cap is cool
enough to touch with your bare hand.
1. Loosen the track. See "Separation of Track".
2. Install tool (A) in order to hold the major bogies in position.

6. Use a depth micrometer (11) to measure the distance between seal ring (6) and the shaft.
The shaft is 90 degrees and four locations away from seal ring (6). The difference in these
measurements must not be more than 0.8 mm (0.0315 inch).
7. If adjustments to seal ring (6) are necessary, use tool (A) to adjust the seal ring on the shaft.
8. Repeat steps 5 to 9 for installation of the toric ring. Also install the seal ring on the other
side of the track roller.
9. Put O-ring seal (12) in position on seal ring (4). Make sure that the O-ring seal is straight on
the seal ring.
10. Put the O-ring seal and seal ring (4) in position in retainer (1). Use tool (A) to install the seal
ring in the retainer. Install the O-ring seal and seal ring (4) until the O-ring seal makes
contact with the bottom of the retainer.
11. Use depth micrometer (11) to measure the distance from the surface of the retainer to the
surface of seal ring (4). The seal rings can be found at four locations. The difference in these
measurements must not be more than 0.1 mm (0.0039 inch).
12. If adjustments to the seal ring are necessary, use tool (A) to adjust the seal ring in the
retainer.
