Checking and adjusting track
shoe tension 1
Checking
1. Run the engine at low idle and drive the
machine forward by the length of track on
ground, and then stop slowly.
2. Place square bar [3] longer than the distance
between idler (1) and carrier roller (2) on the
track shoe.
a As the steel bar, use an angle steel, etc.
which will be deflected less.
3. Test maximum clearance (a) between steel bar
[3] and track shoe.
q Standard maximum clearance (a):
10  30 mm
Adjusting
a If the track shoe tension is abnormal, adjust it
according to the following procedure.
1. Increasing tension
1) Add grease through grease fitting (2) with
a grease gun.
2) To check that the tension is normal, run
the engine at low idle and move the
machine forward by the length of track on
ground, then stop slowly.
3) After adjusting, check the track shoe ten-
sion again according to the above proce-
dure.
a You may add grease until dimension (b)
between the idler guide and track frame
end becomes 0 mm. If the tension is still
low, the pins and bushings are worn
much. In this case, reverse or replace the
pins and bushings.
