MC-9 MAINTENANCE MANUAL
Investigate leaks immediately to determine if fittings have
loosened or cracked and also if hoses have ruptured or worn
through. Take corrective action immediately. Leaks are not only
potentially detrimental to machine operation, but can also result
in added expense caused by the need to replace lost fluids.
WARNING: Personal injury and/or property
damage may result from fire due to the
leakage of flammable fluids such
as
fuel or
lube oil.
SERVICE LIFE
A hose has a limited service life. determined by the tempera-
ture and pressure of the gas or fluid within it time in service,
mounting, ambient temperatures. amount of flexing, and the
vibration it is subject to. With this in mind, TMC/MCI recom-
mends that all hoses be thoroughly inspected at least every 500
operating hours and/or annually. Look for cover damage or
indications of damaged, twisted. worn. crimped, brittle, cracked.
or leaking lines. Hoses having the outer cover worn through or
damaged metal ·reinforcement should be considered unfit for
service.
TMC/MCI further recommends that all hoses be replaced
during major overhaul and/or after a maximum of five years
service. Replacement hose assemblies should always be equal
or superior to the original equipment supplied with the engine.
Review the plumbing and fasten hoses only after the engine
or related mact,inery are installed. Make sure that hoses are
routed and clipped properly to prevent damage from vibration.
abrasion. heat. and mechanical loads. Extra fasteners or read-
. justment of an existing support may be required during the
operating life of a unit.
Hoses routed close to heated surfaces may have a shor-
tened service life. Additional shields or protective sleeves may
extend hose life in special applications where shortened life is
anticipated or has been experienced. Consult with the hose
manufacturer relative to alternate hose compositions where
shields and sleeves are impractical.
The service life of a hose may also be reduced by exposure
to road salt. Some types of hoses with wire braid reinforcement
ar.e subject to oxidation damage and a subsequent reduction in
hose strength.
The proper installation, routing and fitting torque criteria for
hoses can be obtained from major hose suppliers and manu-
facturers.
GREASE FITTING PLATE
A grease fitting mounting ·plate is attached to a master
bracket in the left front service compartment to the rear of the
pitman arm. These zerk fittings are connected to lubricating
lines which lead to points listed on the nameplate. See figure
10-2.
The nameplate explains the function of each fitting.
