Track Loosening/Tightening Procedures; Removing The Rubber Tracks - Timberwolf TW 280TVGTR Instruction Manual

SERVICE INSTRUCTIONS

TRACK LOOSENING/TIGHTENING PROCEDURES

Track tension is maintained by grease in the adjuster unit. Adding
more grease will increase track tension, removing grease will
decrease it.
The grease contained in the hydraulic track tensioner ram is
pressurised. Never release grease nipple (No. 1, Fig. 1) for more
than necessary to slowly release grease to a maximum of five turns.
If the valve is loosened too much you risk expelling grease under
pressure and possible injury to the machine operator. Remove
gravel or mud when they are jammed between the sprocket and
the track link before loosening the track.
1 Locate grease nipple in side frame (Fig. 1) to access the
adjustment system.
2 To loosen the track turn the grease nipple counter-clockwise
slowly, the grease should begin to be expelled after
approximately two turns.
3 If grease does not start to drain out then slowly rotate the track
forward and reverse to free adjuster mechanism - grease may
then be expelled under pressure as track tension is relieved.
4 When you have obtained correct track tension then turn valve
clockwise and tighten it. Clean all traces of extruded grease.
5 To stretch the track connect a grease gun to grease nipple and
add grease until track tension falls within specified values.

REMOVING THE RUBBER TRACKS

Remove gravel or mud when they are jammed between the
sprocket and the track link before loosening the track.
1 Stop your machine on a solid and level surface. Lift it up and
support it in safe conditions.
2 Locate grease nipple in side frame to access to the adjustment
system (No. 1, Fig. 1).
3 To loosen a track turn the grease nipple counter-clockwise
slowly then the grease should begin to be expelled after
approximately 2 turns.
4 If grease does not start to drain out then slowly rotate the track
forward and reverse to free adjuster mechanism.
5 Insert three steel tubes inside the track in the space between
the rollers.
6 Rotate the driving gear in reverse so that the steel tubes
proceed with the track and engage in the track-stretching
wheel.
7 Exercise force sideways to slide the track and lift it off the track-
stretching wheel.
