INSULATION 4573042 - Caterpillar

ADJUSTMENT PROCEDURE: With the machine on the ground, and the balance line installed (if so equipped), make the adjustment as follows:
1. As an initial (first) adjustment, turn each screw out as far as it will go, then turn it in three full turns.2. With the engine at high idle RPM, adjust the screws so each track starts to move at a pilot pressure of 110 10 psi (760 70 kPa) for both forward and reverse operation.3. Make fine adjustments (possibly as little as one-eighth turn or less) until the machine moves in a straight line with a pilot pressure of 138 psi (950 kPa), and still starts to move when the pilot pressure is in the range of 100 to 120 psi (690 to 830 kPa).
