Replacing the Track Pinion
This procedure can be performed either while the robot is on track or
while the robot is on jacking wheels.
1. If the robot is mounted on the track, remove the pinchwheel
assembly from the track motor and move the track motor away from
the rail racking. Using bare fingers, observe the underside of the
pinion to perceive the position of the pinion on the shaft.
2. Remove the 12 x screws from the track pinion.
3. You should now be able to release without applying pressure. If it is
not released easily, use Flair to run the track motor at a slow speed,
eg 20rpm. While the track pinion is rotating, use a heat gun to heat
the pinion to allow it to expand.
Caution
• Take care when heating the pinion with the heat gun to only
direct the gun downwards onto the sides and central when
underneath. If the heat gun is directed at the gearbox seal above
the pinion it can cause damage and create leaks.
• Do not hit the pinion or gearbox with any tools to detach it
from the gearbox. Hammering can cause permanent damage to
the pinion and gearbox.
