TRACKS - BOGIE SYSTEM
BOGIE SYSTEM
The bogie system is built up from movable bogie
arms with pneumatic tyres. The air pressure in the
tyres shall be at least 640 kPa - 6.5 kgf/cm2.
Tensioning of tracks on the tractor
The tracks have the ‘correct tension’ when the up-
per part of the track just touches the second bogie
wheel and the machine is standing on a at sur-
face. The tracks are tensioned by moving the rear
bogie wheel. When the tensioning bolt is tightened
(clockwise), the track is tensioned. Lock the ten-
sioning bolt with the locking nut.
Tensioning of tracks on the trailer
The tracks have the ‘correct tension’ when the up-
per part of the track can be pressed down, with a
force of about 75 kgf, about 10 mm between the
bogie wheels. When the tensioning bolt is tighte-
ned (clockwise), the track is tensioned. Lock the
tensioning bolt with the locking nut.
Changing of tracks on the tractor
Run the machine so that the track joint is at the
front between the driving axle and the front bogie
wheel.
Reduce the track tension as much as possible.
Remove the bolts retaining the three track bars in
the joint.
Jack up the machine with axle stands or the like.
Remove the track and t the new track.
Use a strap to facilitate the joining of the track.
N.B. When the broad snow tracks are to be tted,
the broader rubber belt must be turned outwards,
and the track bars must be turned so that the side
of the bar pulls when the tractor moves
forwards.
See the illustration
Changing of tracks on the trailer
Reduce the track tension as much as possible. Jack
up the trailer with axle stands or the like. Remove
the rear wheel. Take off the track. Fit the new track
in the reverse order.
