4. MAINTENANCE
D. Cold weather add-ons should not be needed.
When cleaning machine, caution should be used around
regulator area. Direct spraying of the regulator is not
good. (Regulator should be covered or protected if
direct spraying will happen). Excessive water pressure
may also loosen wire connections or cause terminal
corrosion. After cleaning, all terminals should be dried
if wet and connections checked for proper seating.
4.30 ENGINE MOUNTING
Check periodically, tighten all mounting hardware for
proper torque. Refer to Torque Charts in Exploded
Views with Parts Section.
4.31 HARDWARE
Inspect all hardware for tightness. Refer to parts
illustrations for proper torque and Torque Charts in
Exploded Views with Parts Section.
4.31.1 Loctite
Loctite 262 threadlocker is required to prevent hard-
ware from loosening.
Refer to Exploded Diagram and Parts List for * where
loctite is required.
4.32 ROLL OVER PROTECTIVE
STRUCTURES (ROPS)
Proper inspection and maintenance procedures can
ensure that ROPS will perform the lifesaving function
they are designed for and expected to do. Make
regular, periodic inspections to ensure ROPS are
damage-free and thus capable of functioning in an
upset.
Generally ROPS/FOPS structures are not intended as
external load carrying members and must not be used
to mount attachments such as pull hooks, winches, side
brooms, etc. without the manufacturers approval.
Modifications to basic design should be avoided, as
recertification is required.
4.32.1 Maintenance of ROPS/Seat Belts
Inspection
Scheduled, frequent visual checks of mounting
hardware by operator or service personnel are
recommended. Inspection with regular service
intervals is suggested. The inspection should check
for:
• Worn, damaged or missing resilient mounts.
Excessive motion or rattling during operation
are indications of a problem.
• Loose, missing or damaged mounting
hardware (bolts, nuts, washers, etc.). Bolts
should be checked for proper torque.
• Cracks in ROPS/FOPS structure and mounting
system. The machine should be cleaned, as
necessary, to allow inspection for cracks in
the structure and mounting system. Rust lines
should be taken as indications of cracks and
verified by inspection. Some cracks will badly
affect the ROPS/FOPS function. If in doubt,
consult the manufacturer.
• Water drainage paths. Clear water drainage
paths so that entrapped water will not freeze
and crack or deform the structure.
• Corrosion. Extensive paint peeling and rust
should be noted and corrective action taken.
• Seat belt. The presence and operability of a
seat belt should be noted. The belt should be
clean, free of dirt and grease and the latch
should function smoothly.
• The structure should be inspected following a
rollover, collision or fire.
Repair
Replace missing or damaged hardware with the
manufacturer’s specified hardware. Re-torque all loose
threaded fasteners to the manufacturer’s specifications.
The manufacturer must be consulted to determine the
repairability of cracks in ROPS/FOPS structures.
