23. Remove any external transmission components as
required, including the transmission temperature
switch (Fig. 7–4).
24. Remove the transmission oil filter and dispose of
properly. Clean the filter mounting surface.
The transmission is now ready for inspection and/or further
service. Refer to the Clark-Hurth T 12000 Powershift
Transmission 3, 4, & 6 Speed Intermediate Drop Mainte-
nance and Service Manual, part number SM T12-3,4,6
ID for information on transmission diagnosis and internal
component repair or replacement.
7.5.2 Transmission Inspection
and Internal Repair
The charging pump and flywheel housing may require
removal for inspection and further transmission disas-
sembly. Mark the housing for return to its original position
as the sides of the transmission case do not align verti-
cally with the engine or with the chassis (Fig. 7–10).
Refer to the Clark-Hurth T 12000 Powershift Transmis-
sion 3, 4, & 6 Speed Intermediate Drop Maintenance and
Service Manual, part number SM T12-3,4,6 ID for infor-
mation on transmission diagnosis and internal component
repair or replacement. If replacing the entire transmis-
sion, transfer the transmission temperature switch to the
replacement transmission. The gear shift solenoids are
included with a new transmission.
7.5.3 Transmission Installation
1. Clean all mating surfaces on both the engine and the
transmission prior to assembly.
2. Obtain and thread four M12 x 80 mm capscrews with
several washers each, as needed, into each
transmission mount bracket boss (Fig. 7–4) to aid in
transmission installation.
3. Temporarily thread two M10 x 1,5 x 63,5mm guide
studs into the engine flywheel housing (Fig. 7–8).
These will be used as alignment dowels.
4. Notice the gaps between the upper and lower halves
of the transmission-to-engine bolt circle (Fig. 7–9).
Use the gaps as an aid in installation, as the sides of
the transmission case do not align vertically with the
engine or with the chassis (Fig. 7–10).
Figure 7–8. Engine flywheel housing guide studs.
5. Use a hoist or overhead crane and sling attached to
the M12 x 80mm capscrews. Raise and position the
transmission within the chassis. DO NOT mount or
align the transmission with the engine using the two
M10 x 1,5 x 63,5 mm guide studs (dowels) at this
time.
IMPORTANT: The flywheel and the torque converter are
factory-balanced units. If applicable, align the flywheel
and the torque converter with the orientation marks made
during the removal procedure.
6. Working through the engine flywheel inspection and
access hole on Cummins engines (Fig. 7–6), or
through the starter mount hole on Perkins engines,
rotate and align a flywheel screw hole with a
transmission drive plate weld nut. Obtain and thread
a 3/8-24 NF x 4" threaded stud, to serve as a drive
plate locating stud, through the flywheel screw hole
and into the drive plate weld nut (Fig. 7–9).

7. Position the transmission onto the two M10 x 1,5 x
63,5 mm guide studs (Fig. 7–8).
WARNING: Risk of severe personal injury.
NEVER lift a transmission alone; enlist the help
of at least one assistant or use a suitable hoist
or overhead crane and sling.
WARNING: The transmission must be properly
installed using fasteners of correct size and
grade torqued to their specified value.
