Loosen the Track
d
CAUTION: Do not loosen valve (1) quickly or loosen
it 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 between
sprockets and track links, remove it before loosening.
1. To loosen the track, slowly turn valve (1)
counterclockwise using long socket 19; grease will
escape from the grease outlet.
2. Between 1 to 1.5 turns of valve (1) is sufficient to loosen
the track.
3. If grease does not drain smoothly, slowly rotate the
raised track.
4. When proper track sag is obtained, turn valve (1)
clockwise and tighten to 90 N·m (9 kgf·m, 66 lbf·ft).
Tighten the Track
d
CAUTION: It is abnormal if the track remains tight
after turning valve (1) counterclockwise or if the track
is still loose after charging grease to fitting (2). In such
cases, NEVER ATTEMPT TO DISASSEMBLE the track or
track adjuster, because of dangerous high-pressure
grease inside the track adjuster. See your authorized
dealer immediately.
To tighten the track, connect a grease gun to grease fitting
(2) and add grease until the sag is within specifications.
