Maintenance
8. Install torque hub in proper position to align with the
drive motor.
9. Place thread-locking adhesive on torque hub bolts
and torque bolts (see Torque Specications in
Section 2).
10. Check O-Ring on the drive motor and replace if
worn.
11. Place thread-locking adhesive on sprocket bolts
and torque bolts (see Torque Specications in
Section 2.)
12. Reinstall rear track roller if previously removed.
13. Fill torque hub with oil. (Page 5-7)
14. Lower paver to ground and reconnect track.
NOTE: Removing pad from chain where master pin
is placed will make reconnecting track easier
from top side at rear of the idler.
15. Retighten track tension valve.
16. Lower conveyor and bolt hopper wings.
17. Start paver and check for any leaks with engine
running.
DO NOT use your bare hands when
checking for hydraulic leaks as serious injury can
result from an oil leak under high pressure. Always
wear safety glasses and protective clothing.
Stop the engine immediately if any
hydraulic leak is noted. DO NOT start the engine
until the leak has been repaired.
Torque Hub
If the torque hub has been damaged or worn, use to
following procedures for replacement:
1. Raise conveyor and insert safety prop. (Page 5-6)
2. Loosen the track tension valve on the track tension
manifold to release pressure.
3. Remove master pin in the track chain behind the
front idler (bottom side).
4. Back paver up until track lays at on the ground.
5. Jack up the paver at least two feet (61 cm) off
the ground for enough clearance under the
undercarraige and place on sturdy jack stands.
6. Remove the two cap screws and lock washers
attaching the drive motor to the torque hub drive.
NOTE: DO NOT disconnect hoses from the hydraulic
drive motor. Hoses are long enough to
slide the motor out. Clean hoses before
reinstalling.
NOTE: Mark location of torque hub to the
undercarriage before removing to ensure the
drive motor is reinstalled in the same position.
NOTE: Sprocket can be removed before the torque
hub by removing the rear track roller and bolts
in the sprocket.
7. Remove bolts holding torque hub to track
undercarriage. (Figure 5-35)
