POWER TRAIN RT9130E SERVICE MANUAL
8. Remove the drive plate locating stud. Install one drive
plate attaching bolt. Snug the bolt but do not tighten.
NOTE: Some engine flywheel housings have a hole
located on the flywheel housing circumference in-line
with the drive plate bolt access hole. A screwdriver or
pry bar used to hold the drive plate against the flywheel
will facilitate installation of the drive plate bolts. Rotate
the engine flywheel and install the remaining seven
flywheel to drive plate attaching bolts and washers.
Snug the bolts but do not tighten. After all eight bolts
and washers have been installed, torque the bolts to 37
to 41 Nm (28 to 30 foot-pounds). This will require
torquing each bolt, then rotating the engine flywheel until
all eight bolts have been torqued.
9. Measure the engine crankshaft end play after the torque
converter has been completely installed on the engine
flywheel. This value must be within 0.025 mm (0.001
inch) of the end play recorded in step 4.
10. Install the two section hydraulic pumps and the single
section hydraulic pump on the torque converter. Refer to
Hydraulic Pumps in Section 2 - HYDRAULIC SYSTEM
for installation of the hydraulic pumps.
11. Install the hydraulic lines to the torque converter.
12. Connect the drive line to the torque converter. Refer to
DRIVE LINES in this section for installation of the drive
line.
13. Install the front section of the engine hood.
14. Service the crane. Refer to Servicing The Crane After
Transmission/Torque Converter Overhaul in this section.
15. Cycle all functions and observe for proper operation.
Servicing The Crane After Transmission/Torque
Converter Overhaul
The transmission/torque converter and its allied hydraulic
system are important links in the drive line between the
engine and the wheels. The proper operation of either the
unit or the system depends greatly on the condition and
operation of the other; therefore, whenever repair or
overhaul of the transmission/torque converter is performed,
the balance of the system must be considered before the job
can be considered completed.
After the overhauled or repaired transmission/torque
converter has been installed in the crane, the oil cooler and
connecting hydraulic system must be thoroughly cleaned.
This can be accomplished in several ways, and a degree of
good judgement must be exercised as to the method
employed.
The following are considered the minimum steps to be taken:
1. Drain the entire system thoroughly.
2. Disconnect and clean all hydraulic lines. Where feasible,
hydraulic lines should be removed from the machine for
cleaning.
3. Replace oil filter elements, cleaning out the filter cases
thoroughly.
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 the
direction of normal oil flow will not adequately clean the
cooler. If necessary, the cooler assembly should be
removed for cleaning, using oil, compressed air and a
steam cleaner for that purpose.
5. Remove the drain plug from the transmission/torque
converter and inspect the interior of the unit housing,
gears, etc. If the presence of considerable foreign
material is noted, it will be necessary for the unit to be
removed, disassembled, and cleaned thoroughly. It is
realized this entails extra labor, however, such labor is a
minor cost compared to the cost of difficulties which can
result from the presence of such foreign material in the
system.
6. Assemble all components and use only the type oil
recommended. Fill the transmission through the fill pipe
until fluid is at the top of the fill range on the dipstick. Run
the engine for two minutes at idle (950 rpm) to prime the
torque converter and hydraulic lines. Recheck the level
of oil in the transmission with the engine running at idle
(950 rpm). Add oil as necessary to bring the level to the
LOW mark on the dipstick. After the oil temperature
reaches 82 to 93 °C (180 to 200 °F), add oil to bring the
level to the FULL mark on the dipstick.
7. Recheck all drain plugs, lines, connections, etc., for
leaks and tighten where necessary.
Lubrication
Type Of Oil
Hydraulic Oil (HYDO) or equivalent. Refer to Section 9 -
LUBRICATION.
Capacity
System Capacity (includes torque converter, lines, and
transmission) - Approximately 32 liters (34 quarts).
CAUTION
Do not use flushing compounds for cleaning purposes.
