Maintenance—Every 100 Hours

Inspect and Re-Torque Track Hardware
Each inspection and re-torquing should be documented
by completing a service report for each unit, placing a
copy of this report in the machine le, and forwarding a
copy to the manufacturer’s attention.
For shoes with missing or loose cap screws and nuts,
remove shoes and clean the mating surface of shoes
and links before replacing cap screws and nuts. The
cap screws must be replaced because they have been
stretched to yield previously.
IMPORTANT: Prevent possible machine damage.
Operating a machine with loose shoes can
cause the cap screws and holes in the shoes
and links to wear, making it difcult to keep
the shoes tight. Loose shoes can also cause
hardware malfunction and loss of shoes.
Improper track shoe cap screw torque will
result in serious damage to the undercarriage
components, shorter life expectancy, and
will void the manufacturer's warranty on the
undercarriage components.
Checking Track Shoe Hardware Torque
NOTE: This procedure is for checking the torque
specication on existing track shoe hardware.
1. Tighten cap screws in sequence to specication.
Specication
Cap Screw—Torque..................................................................1020 N·m
752 lb·ft
2. Cap screws that have turned have reduced tightness
and need to be re-torqued.
3. Check track shoe holes for wear or damage. Replace
as necessary.
Re-Torquing Track Shoe Hardware
NOTE: This procedure is for re-torquing existing track
hardware that was found loose during the Checking
Track Shoe Hardware Torque procedure.
1. Loosen cap screws.
2. Tighten cap screws in sequence to specication.

and debris before installation.
NOTE: This procedure is for installing and torquing new
track shoe hardware to specication.
