Disassembly
The motor should be disassembled in the following order.
Numbers in the parenthesis indicate those as shown in the
Assembly Diagram.
1. Wrap wire around the motor, use a crane to lift it,
wash it with cleaning oil, and then dry it with
compressed air.
2. Discharge oil in the casing (301) through the drain port.
3. Put the motor with the driving shaft (201) facing
downward for easy disassembly.
• Mark parts of the casing (301) and the valve
casing (101) to be engaged.
4. Separate the brake valve (400).
5. Undo and remove the relief valve (107) from the casing
(101).

6. Separate the plug (102) from the valve casing (101)
and disassemble the spring (103) and the plunger
(104).
7. Disassemble the S/R V/V ass'y (105) from the valve
casing (101).
8. Loosen and remove the hexagon socket head cap bolts
(109, 110) from the valve casing (101). (Upon removing
the bolts with the force of the brake spring (310), the
valve casing is separated from the casing
automatically.)
Separate the valve plate (213) from the valve casing
(101).
9. Take out the brake spring (310) from the brake piston
(309).

10. Use a tool to take out the brake piston (309) from the
casing.
To use a hole of bolt, pull it upward straight.
11. Put the motor horizontally and separate the cylinder
block (205) from the driving shaft (201). Then, take out
piston assemblies (203, 204), the retainer (207), the
thrust ball (206), and the collar roller (209). Care
should be taken when taking out the cylinder block
(205), as it may fall off. Also sliding parts of the
cylinder block, the thrust ball, shoes, etc. should not be
damaged. [Do not remove the 2 washers (210), the
spring (211), and the snap ring (212).]
12. Separate 2 friction plates (306) and 3 separation plates
(305) from the casing (301).
(For TSM72 : 4 separation plates and 3 friction plates)
13. Use a plastic hammer to tap the face of the casing
shaft to disassemble the driving shaft (201) consisting
of the swash plate (202) and the ball bearing (303).
Care should be taken not to damage sliding parts of
the oil seal when separating the driving shaft from the
casing.

14. Carry out the following procedures as necessary.
A. Remove the parallel pin (304) from the casing.
B. Remove the ball bearing (303) from the driving
shaft (201). Do not reuse the removed bearing.
C. Use a tool to separate from the casing (301) the
oil seal (302), which should not be reused.
D. Remove the ball bearing (303) from the valve
casing.
Now, disassembly is done. Check every component carefully
to see if there is any defect.

Assembly
Assembly shall be done in the reverse order of disassembly
described above, taking into consideration the following
points:
1. Parts damaged during disassembly should be repaired
without fail and spare parts should be prepared in
advance.
2. Every part should be cleaned enough with cleaning oil
and dried with compressed air before starting
assembly.
3. Sliding parts and bearings should be applied clean
active oil before their assembly.
4. Seal parts of the O-ring and the oil seal should be
replaced according to the standards.
5. Use a torque wrench to tighten or engage bolts and
plugs in accordance with reference torques as shown
in Table 1.
The Following is the Order of Assembly:
1. Put the casing (301) on a proper place.
2. (This procedure is necessary when the oil seal is
separated from the casing.)
Use a tool to insert the oil seal (302) in the casing
(301).
(Give heed to the direction of the oil seal and insert it
until it reaches the end completely.)

3. (This procedure is necessary when the ball bearing
was separated from the driving shaft.)
Install the ball bearing (303) in the driving shaft (201)
by shrinkage fitting.
4. Insert the driving shaft (101) with the ball bearing (303)
in the casing (301) with its output shaft facing upward
and use a hammer to tap the surface of the ball
bearing into the casing. At this point, apply grease to
the lip of the oil seal light and then insert it carefully
that it may not be damaged.
(Wrap a tape around the spline of the driving shaft to
prevent the damage of the spline due to the lip. Tap
the surface of the external circumference evenly until it
reaches the end completely.)
5. (This procedure is necessary when the parallel pin was
removed from the casing.)
Insert the parallel pin (304) in the casing(301).
6. Assemble the swash plate (202) in the casing (301). (It
is easy to assembly when the casing is put
horizontally.)

7. Insert the roller (209) in the cylinder block (205).
[Check if the cylinder block has the washer (210), the
spring (211), and the ring snap (212). Sliding parts of
the cylinder block should not be damaged. Put a roller
into a hole.]
8. Assemble the collar (208) and the thrust ball (206) in
cylinder block (205).
9. Assemble the piston ass'y (203, 204) assembled in the
retainer (207) in the cylinder block (205).
10. Assemble the cylinder block (205) in the driving shaft
(201).
At this point, arrange phases of the thrust ball and the
cylinder block that it may be inserted in the driving
shaft more easily.

11. Insert the separation plate (305) and then the friction
plate (306) in the casing (301). 3 separation plates and
2 friction plates shall be assembled. (To assemble
them, the friction should have the same phase for its
parts where 4 gears are cut face up and down, and do
does the separation plate for its parts where 4 jaws
are cut.)
(For TSM72 : 4 separation plates and 3 friction plates)
12. Insert the O-rings (307, 308) in the casing (301).
(Apply grease to the O-rings light to prevent their
breakage when inserting them in the brake piston.)
13. Assemble the brake piston in the casing (301). If it is
not inserted well due to the resistance of the O-ring,
engage a hex M8 bolt to the brake piston and use a
plastic hammer to tap its surface evenly.
14. Assemble the brake spring (310) in the brake piston
(309). Make sure that the spring should take the seat
of the brake piston firmly.

15. [This procedure is necessary when the ball bearing
(108) was disassembled.] Use a hammer tied to a steel
bar to tap the surface of the ball bearing into the valve
casing (101).
16. Assemble the valve plate (213) in the valve casing
(101) and insert the O-ring (112). Apply grease to the
engaging part of the valve plate light (to prevent its
falling off).
17. Mount the valve casing (101) on the casing (301) and
connect them with hex socket head cap bolts (109,
110). Give heed to the mounting direction of the valve
casing (and its external measures).
Care should be taken not to have the valve plate fall
off and the brake spring fall down. Tighten hex socket
head cap bolts uniformly.
18. Insert the plunger (104) and the spring (103) in the
valve casing (101) and engage the plug (102) with the
O ring (106) to the valve casing (101). Make sure that
the plunger moves smooth.
