HOW TO USE THIS MANUAL
1
To help identify parts and clarify procedure steps, there are exploded diagrams at the
start of each removal and disassembly section.
2
Numbers are given in the order of the jobs in the exploded diagram. A circled number
indicates a disassembly step.
3
Symbols indicate parts to be lubricated or replaced (see “SYMBOLS”).
4
A job instruction chart accompanies the exploded diagram, providing the order of jobs,
names of parts, notes in jobs, etc.
Example:
O-ring size
39.5 x 2.5 mm: Inside diameter (D) x ring diameter (d)
5
Dimension figures and the number of parts, are provided for fasteners that require a
tightening torque:
Example:
Bolt or screw size
10 x 25 mm (2) : M10(D) x 25 mm (L) (2pieces)

Jobs requiring more information (such as special tools and technical data) are described
sequentially.
