Removal and Installation of Muffler

d.Steel ball (10) attachment

Attach steel balls (10) in the spherical hole sections of the bottom of the case (1).

Caution: Before attaching the steel balls (10), apply hydraulic oil to the inner diameter surface of the spherical holes of the case (1) and the steel balls (10).

e.Shaft (3) attachment

Use the bearing press-fit jig to press fit the roller bearing (13) inner race to the shaft (3). Next, attach the shaft (3) to the center of the case (1).

Caution: •When attaching the roller bearing (13) inner race, attach it vertically. •After attaching the shaft (3), check that it rotates smoothly.

f. Swash plate (9) attachment

Point the slanted surface of the swash plate (9) upwards and attach the swash plate to the case (1).

Caution: •Attach by matching the rear surface spherical holes of the swash plate (9) with the steel balls (10). •Apply hydraulic oil to the surface of the steel balls (10), then attach the swash plate (9). •After attaching the swash plate (9), check that it moves smoothly. g.Assembly of cylinder block (4), piston assemblies (6), retainer plate (7), retainer holder (8) and springs (17) (Hereinafter, this is called the cylinder block assembly.) 1.Point the cylinder block (4) sliding surface against the valve plate (5) downwards and place the cylinder block (4) on the work platform. Attach the 9 springs (17) to the cylinder block (4).

Caution: For the sake of installation, be careful not to scratch the cylinder block (4) sliding surface against the valve plate (5). Scratching may cause a reduction in motor performance and early damage to the motor.

2.Using the cylinder block (4) and retainer holder (8), attach the retainer holder (8) so that they sandwich the springs (17).

Caution: •For the sake of installation, be careful not to scratch the cylinder block (4) sliding surface against the valve plate (5). Scratching may cause a reduction in motor performance and early damage to the motor. •When attaching the retainer holder (8), attach it in such a way that the springs (17) do not come off from the cylinder block (4) holes and do not fall.
