3. Tighten the special cap screw on the opposite side of the same undercarriage, to
specification. Cap screw torque is 300 Nm (221 ft-lb). Tighten cap screw loosened
in step 2 to the same specification.
Note: A single full turn is the standard
increment during adjustment. Lessen this amount as final adjustment is
approached.
4. Recheck track alignment and adjust until suitable clearance is obtained on both
sides of the guide lugs.
Note: Lock plates are reversible for double the index
increments. If needed, increase torque on the special cap screw slightly
allowing advancement to a suitable lock plate position.
5. When alignment is complete reinstall the lock plates and tighten cap screws to
their required torque specification of 130 Nm (95 lb-ft).
6.3 Track system inspection
Track System
Inspect track system for material build-up on frames and wheels. Clean material from
undercarriage. Material build up on idler wheels can affect track alignment and produce
additional heat buildup.
Idlers and midrollers
Check the general condition of the idlers and midrollers, in particular on inner flange
surface of the wheels. Excessive wear in these areas can be caused by track alignment
issue, debris ingestion or continuous hillside work.
Rubber track guide lugs
Guide lugs keep the track on the track system. Proper alignment of the track is essential
to improving overall life and decreasing operating costs. If track is misaligned or operating
on side slopes, guide lug wear or damage may occur. Also guide lug damage may occur
if proper break-in procedures are not followed or system is operated outside the
maximum speed recommendations listed in this manual. Monitoring guide lugs can alert
the operator to track or undercarriage problems. In general, if caught and corrected early,
no loss of performance or component life are experienced.
Track carcass
Inspect track surface to remove imbedded stones or debris. This contamination can work
its way into the track and damage the steel cable.
Steel wire may come out from the track carcass without affecting the performance of the
track. Remove loose wires by cutting them at the rubber surface.
Track tread
Muddy soils usually cause limited wear, while roading long distances can bring about
accelerated tread wear. Due to the crown of the road, and deflection in the system, the
