EXCERPT:

TESTING AND ADJUSTING
ADJUSTING CLEARANCE OF IDLER
- If the lateral guide and vertical guide of the idler are so worn that the idler runs out or slants, adjust the clearance of the idler according to the following procedure.
1. Lateral adjustment
1) Drive the machine 1 – 2 m on flat ground, and then measure clearance a between the track frame and guide plate (at 4 places on both sides, inside, and outside).
2) If clearance a is larger than 4 mm, loosen bolt (1) and reduce shim (2).
• Standard clearance a on each side: 0.5 – 1.0 mm
• Sorts of shim thickness: 0.5 mm, 1.0 mm
2. Vertical adjustment
1) Measure clearance b, subtract 2 mm from it, and record the result (quantity of adjustment).
• Example: When clearance b is 5 mm
The quantity of adjustment is 5 – 2 = 3 mm.
2) Loosen bolts (3) (4 pieces on inside and outside) until the reaction force of the spring is lost.
3) Loosen bolt (1). Do not loosen it more than 3 turns, however.
4) Pull up vertical guide (4) with a bar, etc. and pull out shim (5) by the quantity of adjustment obtained in 1) above.
5) Add shim (5) pulled out onto shim (6). (8 places in total on both sides, inside, and outside)
- The total number of shims (5) and (6) before adjustment must be the same as that after adjustment.
• Sorts of shim thickness: 1 mm, 2 mm
INSPECTING WEAR OF
SPROCKET
- Make a copy of the “Full-scale drawing of sprocket tooth profile” on a transparent sheet and apply it to the sprocket directly to see if the sprocket is serviceable.

TESTING AND ADJUSTING
TRACK SHOE TENSION
Testing
1. Drive the machine slowly on a level place, then stop it.
- Do not apply the brake when stopping.
2. Place straight steel bar (1) between the idler and front carrier roller and measure clearance a between the bottom of the steel bar and shoe grouser.
• Standard clearance a: 20 – 30mm
Adjusting
- If the track shoe tension is abnormal, adjust it according to the following procedure.
1. Remove cover (2).
2. When the tension is too high
Loosen plug (3) to discharge the grease.
Since the high-pressure grease may spout out, do not loosen the plug more than 1 turn.
Plug: 59 – 88Nm {6 – 9kgm}
3. When tension is low
Add grease through grease fitting (1).
- If the track shoe is not tensed well, drive the machine forward and in reverse slowly.
