Komatsu — 24.2 WHEN REQUIRED

24. SERVICE PROCEDURE 24.2.10 ADJUST IDLER CLEARANCE Since the idlers are forced to move forward and backward by an external force the guide plates will be worn out. Wear of these plates will cause the vibration of idlers from side to side or inclination of the idlers, and running off of track links from the idlers or unevenly worn idler and links may result. Therefore, adjust the idlers according to the following proce- dure. ADJUSTMENT 1. Move machine about 1 or 2 meters (3.3 - 6.6 ft) on a flat ground and measure the clearance A (4 locations: left, right, inside and outside) between the track frame and the guide plate. 2.

If the clearance A exceeds 3.0 mm (0.12 in), loosen bolt 0, and pull out the shim to adjust the clearance at one end to 1.0 mm Clearance A AE077841 (0.04 in). Thickness of one shim is 1.0 mm (0.04 in) 24.2.11 ADJUST ANGLE OF BLADE EDGE It is dangerous if the work equipment moves by mistake when adjusting angle of the blade edge. Set the work equipment in a stable condition, then stop the engine and apply the locks l Hydraulic tiltdozer Adjust the angle of the blade edge to match the type of soil. METHOD OF ADJUSTMENT Turn the brace with bar handle @ and adjust the length @I between the joints to change the angle (0) of the edge of the blade as follows. INCREASE length to INCREASE angle.

DECREASE length to DECREASE angle. Standard blade angle: 55” AE077970 3-35
