RUNNING-IN AFTER OVERHAULING
A completely overhauled tractor should undergo
a thorough check over before leaving the service
station.
Make sure that all parts are properly installed and
all bolts are drawn up tight. Carefully inspect all
units, check adjustments as far as accessible and
correct if necessary. Remember, it is better to check
three times than commit one error.
Fill the transmission case with specified lubricant and
grease the tractor liberally in accordance with the
lubrication guide of the “Operators Manual”. Be sure
that all instruments and controls function properly
before preparing the engine for running-in.
Fill the engine crankcase, the fuel injection pump
and the governor housing with specified lubricant.
Fill the cooling system.
Fill the fuel tank with Diesel fuel and vent the fuel
system properly. Start the engine in the conventional
manner and let it run at medium speed for about
five minutes. Closely observe the engine to see that
all parts work freely and the engine operates
smoothly.
Check the oil pressure.
With the engine stopped check the crankcase oil
level and make sure the pressure feed lubrication
functions properly and no bearing is starved. Restart
the engine and let it run at medium speed for
approximately one hour.
If new cylinder sleeves and pistons were installed
it is necessary to run-in for another hour during
which the engine is accelerated to full speed for
short periods.
Closely observe the engine during the running in
time and note any faults for later correction.
When time is up, stop the engine and readjust as
follows:
Retighten injection nozzle stud nuts.
Check fan belt tension.
Check oil in engine crankcase.
Draw up all bolts and nuts in accordance with the
tightening scale.
Check for evidence of oil leakage and inspect all
hose and pipe connection for leaks.
Correct faults observed during the running-in time.
Finally, a trial run is made to test chassis and
transmission.
This trial run should last at least 15 minutes and
consist of the following tests:
Testing the engine clutch.
Testing the five forward speeds and the reverse
speed.
Testing the steering.
Testing the brakes.
Testing the electrical system.
Make a final test with tractor under load.
It is important that faults revealed by these tests
be remedied without delay.
After an overhaul every part or unit of the tractor
should function properly and be up to the standards
and requirements described in the various sections
of this manual. Only then can you expect ready and
efficient performance and trouble-free operation
the year round.
