Paccar TX-18 - Lubrication

CAUTION
The use of sealing additives or soluble
oils in
the cooling system can cause
damage to the engine. These additives
can plug various areas of the radiator,
EGR system and oil cooler. The plug-
ging of the cooling system can hamper
heat transfer, causing internal engine
damage. DO NOT use sealing addi-
tives or soluble oils in the cooling sys-
tem. The use of sealing additives can
• Build up in coolant low-flow
areas
• Plug the radiator and oil cooler
• Damage the water pump seal
• Damage heat transfer surfaces
• Damage seals and hoses
• Corrode brass and copper
Failure to comply may result in equip-
ment or property damage.
Lubrication
Proper lubrication procedures are
important for a good maintenance
program. If the lubricant is not doing its job
or if the lubricant level is ignored, all other
maintenance procedures are not going to
keep the transmission running or assure
long transmission life.
Lubricant changes should be based on a
combination of the intervals shown in
vehicle operator's manual, the Lubrication
and Maintenance service manual, and user
judgment – based on vehicle application
and operating environment. Extending
drain intervals beyond those shown in the
tables is not recommended and will put
warranties at risk.
To ensure that transmission internal parts
are amply lubricated, do the following:
•
Maintain lubricant level and inspect
regularly.
• Follow maintenance intervals, see
Preventative Maintenance on page
45.
• Use the correct grade and type of
lubricant, see Transmission Lube
Specification on page 62.
• Buy lubricant from an approved
dealer.
Draining the Transmission
Draining lubricating fluid from the
transmission should only be performed
during fluid replacement or a repair. Take
your vehicle to a PACCAR Powertrain
distributor for maintenance processes that
require draining transmission lubricant.
See Transmission Lubricant Capacities on
page 62 and Transmission Lube
Specification on page 62 for more
information on the amount and type of
lubricant required for this transmission.
