Loosen Track (Steel Crawler)
WARNING: Do not loosen valve (1) too quickly or
too much as high-pressure grease in the
adjusting cylinder may spout out. Loosen
carefully, keeping body parts and face away from
valve (1). Never loosen grease fitting (2).
IMPORTANT: When gravel or mud is packed around
the components in the undercarriage,
remove it before loosening valve (1).
1. To loosen track, slowly turn valve (1)
counterclockwise using a socket wrench (long socket
19); grease will escape from grease outlet.
2. Between 1 and 1.5 turns of valve (1) are sufficient to
loosen track. Never attempt to loosen the valve
further.
3. If grease does not drain smoothly, raise the track to
be loosed off the ground and slowly rotate the track.
4. When proper track sag is obtained, turn valve (1)
clockwise and tighten it to 88 N
⋅
m (9 kgf
⋅
m, 65 lbf

ft).
Tighten Track (Steel Crawler)
WARNING: In case the track sag is not adjustable,
this is a very hazardous situation. Since the track
adjuster spring is excessively loaded, the grease
pressure inside the track adjuster cylinder is very
high. Incorrect adjustment or disassembly may
result in personal injury and/or death.
Immediately consult your nearest Hitachi dealer
for repair.
To tighten track, connect a grease gun to cylinder
grease fitting (2) located inside the side frame and
add grease until the sag is within specifications.
