Amadas 9980 - Breaking in the Engine

9980 Self-Propelled Peanut Combine Prestarting Checks
Breaking in the Engine
The engine is ready for normal operation.
However, extra care during the first 100 hours
of operation will result in more satisfactory
long-term engine performance and life.
• This engine is factory filled with John Deere
Engine Break-in Oil. Do NOT exceed 100
hours of operation with break-in oil.
•
Operate the engine at heavy loads with
minimal idling during the break-in period.
•
If engine has significant operating time at
idle, constant speeds, and/or light load
usage, or makeup oil is required in the first
100 hour period, a longer break-in period
may be required. In thi
s situation, an
additional 100 hour break-
in period is
recommended using a new change of John
Deere Engine Break-in Oil and a new John
Deere oil filter.
• Check engine oil level more frequently
during the engine break-
in period. If oil
must be added during this period, John
Deere Engine Break-in Oil is preferred.
•
Note that some increase in consumption
may be expected when low viscosity oils
are used. Check oil levels more frequently
if used.
•
During the first 20 hours, avoid prolonged
periods of engine idling or sustained
maximum load operation. If the engine will
idle longer than 5 minutes, stop the engine.
• After the first 100 hours maximum, change
the engine oil and replace the engine oil
filter. Fill the crankcase with seasonal
viscosity grade oil (see Chapter 19, Fuel
and Lubricants, for oil recommendations).
Checks
It is very important you perform the basic pre-
start checks during the break-in period, as well
as the checks described in this section after 50
and 100 hours.
IMPORTANT! Do NOT add makeup oil
until the oil level is below the “ADD” mark
on the dipstick. John Deere Engine
Break-in Oil (TY22041) should be used
to make up any oil consumed during the
break-in period.
Do NOT use PLUS-50 Engine Oil during
the break-in period of a new engine or
engine that has had a major overhaul.
PLUS-
50 oil will not allow a new or
overhauled engine to properly wear
during this break-in period.
IMPORTANT! Do NOT fill above the
FULL mark. Oil levels anywhere within
the cross hatch marks are considered in
the acceptable operating range.
