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.

Numbers are given in the order of the jobs in the exploded diagram. A circled number
indicates a disassembly step.

Symbols indicate parts to be lubricated or replaced (see “SYMBOLS”).

A job instruction chart accompanines the exploded daiagram, providing the order of
jobs, names of parts, notes in jobs, etc.
Example:
O-ring size

Dimension figures and the number of parts are provided for fasteners that require a tight-
ening torque:
Example:
