13.)Assembling the thrust plate (26)

Measure the step between the end surface of the housing (4) and that of the thrust plate (23) using a thrust plate selecting jig, and select the thrust plate (26) according to the table below to assemble it.

Note:

Assemble the thrust plate (26) by aligning the central hole in the thrust plate with the convex section of the drive gear (25).

Step Dimension Applicable Thrust Plate 1.20 to 0.67 20941-62306 0.66 to 0.04 20941-62307 0.03 to -0.16 20941-62308 -0.17 to -0.41 20941-62309 -0.42 to -0.80 B0841-23017

14.)Assembling the holder (27)

Completely remove foreign matter on the alignment surface of the housing (4) and cover (27).

Next, degrease the alignment surface of the housing (4) and cover (27) well.

Next, apply liquid packing at the corner of the spigot joint portion of the cover (27) and housing (4) alignment surface. Then align the screw bore of the housing (4) with the bolt bore to install the cover (27) onto the housing (4).

Lastly, install the socket head bolt (28) and tighten the socket head bolt (28) at the specified torque.

15.)Assembling the plug (29)

Remove the O-ring (30) attached to the plug (29).

Replacing it, assemble a new O-ring onto the plug (29).

Next, assemble the plug (29) onto each of the oil fill, discharge and level ports (3 ports) of the cover (27) and tighten them at the specified torque.

That completes the assembly of the reduction gear section. The next section describes the assembly of the motor section. Refer to "(2) Assembly of Motor" to proceed with the assembling procedure.
