Chapter 5 Installation

• For the pin-bolt clamping output shaft type, drill both a pin pilot hole for the reduction gear and a
Step 3
hole on the shaft installation component simultaneously using a reamer, and then tap the taper pin.
• When drilling holes using a reamer, masking is necessary so that cutting chips will not enter the
reduction gear.
(Reference: “4.2.9. Taper pin with screw” )
Note: For the two-crank shaft type, rotate the reduction gear until the marked position on the crank
shaft reaches the position indicated in Fig. 5-29. Then, drill holes simultaneously using a reamer.
If the cutting chips are trapped in the reduction gear while drilling holes using a reamer, they could
adhere to the gear, and eventually cause deterioration of performance, such as abnormal noise,
vibration, and torque irregularity, and durability. Also, if the liquid sealant adheres to the lip of the oil
seal, it could cause leakage of the lubricant.
• Insert an O-ring (II) into the groove on the case for
Step 4
the reduction gear.
• If the product does not feature an O-ring groove, seal
the section using a liquid sealant, etc.
(Reference: “4.2.5 Liquid sealant” and “4.2.6 O-rings”)
