Loosen Track (Steel Crawler)
CAUTION: 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).
MAINTENANCE
IMPORTANT: When gravel or mud is packed around the
components in the undercarriage, remove
it before loosening valve (1).
d
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)
CAUTION: 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.
