Chapter 4 Preparations for Installation

Shaft installation component
• Prepare the shaft installation component for the output shaft of the reduction gear.
Confirm that the design of the prepared shaft installation component conforms to the size and quantity
of the bolts shown in Table 4-2 in “4.2.2 Reduction gear mounting bolts”.
When preparing the shaft installation component, take extra care not to cover the tapped holes for
injecting/draining grease. If the tapped holes are covered, it will be difficult to replace the lubricant.
