3. Disconnect the old hose.
4. Replace the old hose with a new hose.
5. Install hose clamps which have been inspected or
install new hose clamps. Refer to Specifications,
SENR3130, “Torque Specifications” “Hose
Clamps” for information about selecting and
installing the proper hose clamps.
6.
Refill the lubrication system. Refer to this
Operation and Maintenance Manual, “Engine Oil
Level - Check” in order to ensure that the
lubrication system is filled with the proper amount
of engine oil.
7. Start the engine. Inspect the lubrication system for
leaks.
Air System
1. Remove the hose clamps.
2. Disconnect the old hose.
3. Replace the old hose with a new hose.
4.
Install hose clamps which have been inspected or
install new hose clamps. Refer to Specifications,
SENR3130, “Torque Specifications” “Hose
Clamps” for information about selecting and
installing the proper hose clamps.
Note: The bellows and the V-clamps that are used on
the exhaust bellows should never be reused.
5. Start the engine. Inspect the air lines for leaks.

Overhaul Considerations
SMCS Code: 7595-043
Reduced hours of operation at full load will result in a
lower average power demand. A decreased average
power demand should increase both the engine
service life and the overhaul interval.
The need for an overhaul is generally indicated by
increased fuel consumption and by reduced power.
The following factors are important when a decision
is being made on the proper time for an engine
overhaul:
• The need for preventive maintenance
• The quality of the fuel that is being used
• The operating conditions
• The results of the S·O·S analysis
Oil Consumption as an Overhaul
Indicator
Oil consumption, fuel consumption, and maintenance
information can be used to estimate the total
operating cost for your Caterpillar engine. Oil
consumption can also be used to estimate the
required capacity of a makeup oil tank that is suitable
for the maintenance intervals.
Oil consumption is in proportion to the percentage of
the rated engine load. As the percentage of the
engine load is increased, the amount of oil that is
consumed per hour also increases.
The oil consumption rate (brake specific oil
consumption) is measured in grams per kW/h (lb per
bhp). The brake specific oil consumption (BSOC)
depends on the engine load. Consult your Caterpillar
dealer for assistance in determining the typical oil
consumption rate for your engine.
When an engine's oil consumption has risen to three
times the original oil consumption rate due to normal
wear, an engine overhaul should be scheduled.
There may be a corresponding increase in blowby
and a slight increase in fuel consumption.
Overhaul Recommendation
Caterpillar recommends replacement of the engine.
For more information about replacement of the
engine, see your Caterpillar dealer. Engine
components are available in a standard size only.
Cleaning
Caterpillar recommends the use of Hydrosolv Liquid
Cleaners. Table 31 lists the Hydrosolv Liquid
Cleaners that are available from your Caterpillar
dealer.
