12-4.)Secure the cylinder block (1-4-1) in place on the manual press deck with the sliding surface up. Press the collar (1-4-8) with the snap ring (1-4-5) removal jig to make the spring (1-4-7) deflect and remove the snap ring (1-4-5) using a snap ring pliers.

Note:

When removing the snap ring (1-4-5), follow the instructions below in order to avoid injuries. a.When removing 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 removing the snap ring, always use the disassembling jig and check that the claws of the snap ring pliers are engaged in the snap ring hole before proceeding with the work.

12-5.)Remove the collar (1-4-8), spring (1-4-7) and collar (1-4-6) from the cylinder block (1-4-1).

13.)Removing the swash plate (1-5)

Remove the swash plate (1-5) from the flange (1-1).

Note:

When removing the swash plate (1-5), follow the instructions below. a.Take care not to damage the sliding surface of the swash plate (1-5). Damaging it would fail the design performance. b.The swash plate (1-5) may come out with the piston assembly (1-7) and steel ball (1-6). In that case, take precautions to prevent the steel ball (1-6) from falling.

14.)Removing the piston sssembly (1-7) and steel ball (1-6)

Remove the piston assembly (1-7) from the flange (1-1) and remove the spring (1-20).

Remove the steel ball (1-6) from the flange (1-1).

Note:

As the steel ball (1-6) is not easy to detach, follow the steps below to remove it. a.As the steel ball (1-6) is mounted on the flange (1-1), degrease the unit with white kerosene, thinner or the like. b.Remove the steel ball (1-6) from the flange (11), using magnet.

15.)Removing the shaft (1-3)

Remove the shaft (1-3) and ball bearing (1-8) from the flange (1-1).

Note:

When removing the shaft (1-3), follow the instructions below. a.Take care not to damage the spline section of the shaft (1-3). b.Take care not to damage the oil seal sliding section (1-12) of the shaft (1-3). Damaging will cause oil leakage.

16.)Discharge lubricating oil from the reduction gear

Next, before disassembling the reduction gear section, install eyebolts at two locations opposed to each other by using the shave of the flange (11) and then lift the reduction gear with a crane.

Remove 2 plugs (29) and discharge lubricating oil from the reduction gear.

Note:

a.Prepare an oil catcher prior to the operation. b.When lifting with a crane, avoid lifting too high.

Keep it as low as possible (around the knee level) during the operation.
