Servicing Machine After Component Overhaul
The transmission, torque converter, and its allied hydraulic system are important links in the driveline between the
engine and the wheels. The proper operation of either unit depends greatly on the condition and operation of the other.
Therefore, whenever repair or overhaul of one unit is performed, the balance of the system must be considered before
the job can be considered complete.
After the overhauled or repaired transmission has been installed in the machine, the oil cooler, and connecting hydraulic
system must be thoroughly cleaned. This can be accomplished in several manners and a degree of judgement must be
exercised as to the method employed.
The following are considered the minimum steps to be taken:
1.
Drain entire system thoroughly.
2.
Disconnect and clean all hydraulic lines. Where feasible hydraulic lines should be removed from machine for clean-
ing.
3.
Replace oil filter element.
4.
The oil cooler must be thoroughly cleaned. The cooler should be “back flushed” with oil and compressed air until all
foreign material has been removed. Flushing in direction of normal oil flow will not adequately clean the cooler. If
necessary, cooler assembly should be removed from machine for cleaning, using oil, compressed air, and steam
cleaner for that purpose.
IMPORTANT:
NEVER use flushing compounds for cleaning purposes.
5.
Reassemble all components and use only type oil (See chapter 4.1.1 “Recommended lubricants”).
Fill the transmission through filler opening until fluid comes up to FULL mark on transmission dipstick.
•
Remove filler plug and fill oil until FULL mark.
•
Run engine two minutes at 500 - 600 RPM to prime torque converter and hydraulic lines.
•
Recheck level of fluid in transmission with engine running at idle (500 - 600 RPM).
•
Add quantity necessary to bring fluid level to LOW mark on dipstick.
•
Recheck with hot oil 180 – 200°F [82.2 - 93.3°C].
•
Adjust oil level to FULL mark on dipstick.
6.
Recheck all drain plugs, lines, connections, etc… for leaks and tighten where necessary.
7.
Perform automatic calibration.
