6.)Assembling the cylinder block assembly (1-4)

6-1.) Place the cylinder block (1-4-1) on the work bench of a manual press with its surface sliding against the valve plate (121) up. With the graded side of the collar (1-4-6) down, assemble it into the cylinder block (1-4-1), and place the spring (1-4-7) and the collar (1-4-8), in that order, on the collar (1-4-6).

6-2.) Using a jig, press in the upper surface of the collar (1-4-8) and assemble the snap ring (1-4-5).

Note:

a.When assembling the snap ring (1-4-5) with snap ring pliers, the snap ring may drop out of the snap ring pliers due to its hardness, leading to injury. When assembling the snap ring, always use a jig and check that the claws of the snap ring pliers are engaged in the snap ring hole before proceeding with the work. b.When it is difficult to contract the snap ring, use snap ring pliers that are onesize larger than required. c.When pressing in the collar (1-4-8), be sure to align the center of the cylinder block with that of the press.

6-3.) Place the cylinder block (1-4-1) on the work bench with its surface sliding against the valve plate (1-21) down.

Assemble 3 pins (1-4-9) into the inclined holes of the cylinder block.

Note:

a.When placing the cylinder block (1-4-1) on the work bench, check that no foreign matter is present on it. b.Take care not to damage the sliding surface of the cylinder block (1-4-1) that slides against the valve plate (1-21).

Damaging the sliding surface may affect the motor performance, which may lead to early failure of the motor. c.When assembling the pin (1-4-9), assemble it after applying grease in the pin halls.

6-4.) Assemble the retainer holder (1-4-4) onto the cylinder block (1-4-1).

6-5.) With the surface having tapered surface on the side down, assembly 9 piston assembly (1-4-2) onto the retainer plate (1-4-3).

6-6.) Assembly the piston assembly (1-4-2) onto the cylinder block (1-4-1).

Note:

a.After applying hydraulic oil in the halls (at 9 locations) for assembling the cylinder block (1-4-1), assemble the piston assembly (1-4-2). b.Apply hydraulic oil on the spherical surface of the retainer holder (1-4-4), and then proceed with the assembling procedure.

7.)Assembling the cylinder block assembly (1-4)

With the sliding surface of the valve plate (1-21) of the cylinder block assembly (1-4) up, assemble the cylinder block assembly (1-4) into the flange (1-1) while engaging the inner teeth spline of the cylinder block (1-4-1) with the external teeth splines of the retainer holder (1-44) and shaft (1-3).

Note:

a.When assembling, take care not to allow the piston assembly (1-4-2), retainer plate (1-4-3), retainer holder (1-4-4), etc. to drop out of the cylinder block assembly (1-4). b.Prior to the assembling procedure, apply hydraulic oil on the surface of the swash plate (1-5) and the sliding surface of the piston assembly (1-4-2).

8.)Assembling the disk plate (1-13)

While engaging the inner teeth of the disk plate (1-13) with the external teeth of the cylinder block (1-4-1), assemble the disk plate onto the flange (1-1).

Also, assemble it onto the flange (1-1) so that the peripheral arc section of the friction plate (1-14) is aligned with the notch section of the flange (11).

According to the procedures above, assemble the disk plate (1-13) and the friction plate (1-14), in that order.

Note:

The disk plate (1-13) is a wet-type disk. Prior to the assembling procedure, soak the portion of friction material in hydraulic oil to let it absorb hydraulic oil adequately.
