4.5.3.4 Check track tension
Run engine at low idling, move the machine
forward a distance equals to the length of
track on ground. Then stop the machine.
As shown in right fig, choose a straight long
rod; place it on track over idler (1) and carrier
roller (2), measure the max distance “A”
between upper surface of track and bottom
surface of the rod.
Standard deflection “A” should be 20-28 mm
(0.8-1.1 in).
If the track tension is not at standard value,
adjust it in the following manner:
1) Pump in grease through grease fitting(2)
with a grease pump.(pump fitting (2) and
plug screw (1) are integral)
2) To check track to evaluate the proper
tension of track. Gradually move machine
forward（7-8 m（23 ft - 26 ft 3 in）.
3) Recheck track tension, if the tension is
improper, re-adjust it.
Warning
There is a hazard that plug screw may
fly out under high lubrication grease
pressure. Never loosen plug (1) by
over one turn. (1).
Do not loosen any parts other than
