CHAPTER 6  DISASSEMBLY/REASSEMBLY AND LUBRICATION

This chapter details procedures for disassembling and reassembling the machine together with related
notes. The disassembly order flow provided enables you to see at a glance the quickest way to get to
component(s) involved.

At the start of a disassembly job, you check the disassembly order flow that guides you through a
shortcut to the target components.

This chapter also covers screw tightening torques and lubrication points to which the specified
lubricants should be applied during reassembly jobs.
