6.5 Track Removal
1. Place the undercarriage on a level surface and loosen the nuts on the idler wheels.
Undercarriage may not need removal from the implement to be worked on.
2. Locate the tension module located between the rear idlers. Remove the 2 bolts
fastening the rotation lock to the frame. Remove the lock.
3. Turn the tension screw clockwise to compress the spring which loosens the track.
Turn the screw until it bottoms out on the stop. Do not force the spring past this
point.
4. Using a suitable lifting device raise the undercarriage until there is clearance
between the wheels and track.
5. Remove the wheel bolts and torque plate castings.
Note: idler wheels weigh
90kg (200lbs) and will roll easily on a firm surface. Place a stop under
removed wheels to stop rolling and potential injury.
6. Remove the inner idler wheel.
7. Using a suitable lifting device, lift the track slightly near the front and rear idlers,
pulling slightly away and back from the undercarriage to remove the track.
Note: If
using a forklift or other steel lifting device, ensure the tines or lifting surface
does not have sharp edges or track damage may occur.
8. Lift the track up and away from the undercarriage, placing in a suitable location for
installation.
6.6 Track Installation
9. Raise the undercarriage roughly 12 in. from the ground to allow for the lower
surface of the belt to slide underneath.
10. Lift the track and install on the top carrier rollers. Push the bottom of the track
under the midrollers aligning with the front and rear idlers.
11. Install the idler wheels removed previously, ensuring the guide lugs are positioned
properly between the midrollers and idlers.
12. Lower the undercarriage assembly to the ground. Turn the tensioning screw
counterclockwise to extend the tensioning spring. The screw should be retracted
until there is no preload on the spring. Thread the screw in to the onset of
compression and back off ½ turn.
13. Install tensioning screw rotation lock and torque retainer bolts to 122 N-m (90 lb-ft).
