Personal injury or death can result from grease under pressure.Grease coming out of the relief valve under pressure can penetrate the body causing injury or death.Do not watch the relief valve to see if grease is escaping. Watch the track or track adjustment cylinder to see if the track is being loosened.Loosen the relief valve one turn only.If track does not loosen, close the relief valve and contact your Caterpillar dealer.
Move the machine forward. Allow the machine to coast to a stop without the use of the service brakes. Adjust the tracks while you are in the typical operating conditions for the machine. If packing conditions prevail on the workplace, the tracks should be adjusted without removing the packed material.
Make sure that the ripper is raised, if necessary.
To measure the sag in the track, stretch a string over the grousers that are between the sprocket and the front idler. Take the measurement from the string to the top of the grouser at the maximum measurement. Dimension (A) is the maximum distance between the string and the grouser.
Illustration 2 g01109482If a machine does not have carrier rollers, the sag in the track is measured between the sprocket and the front idler. The correct adjustment of dimension (A) is 165 10 mm (6.5 .4 inch).

Track adjustment with carrier rollers
If the machine is equipped with a carrier roller, calculate the average of dimension (B) and dimension (C). The correct average value is 75 10 mm (3.0 0.4 inch).Loose Track Adjustment

Add multipurpose grease (MPGM) through track adjustment valve (1). Add the MPGM until dimension (A) is correct.
Operate the machine back and forth in order to equalize the pressure. Allow the machine to coast to a complete stop. Do not use the brakes.
Remeasure dimension (A). Tight Track Adjustment
Loosen relief valve (2) by one turn of 360 degrees. Allow the grease to escape.
Close the relief valve. Tighten the valve to a torque of 34 7 N m (25 5 lb ft).
Add MPGM through track adjustment valve (1). Add grease until dimension (A) is correct.
Install the access cover. Bolt Torque for Track Shoes
The torque requirement for track shoe bolts is dependent upon which type of track link the track shoe is attached to. There are two different master link designs for this machine with a different bolt torque for each of the two master link design types. Bolt torque for track links that are not master links are different than the bolt torque for either type of master track link.Track Shoes (Five Tooth Master Link)
