Good working practices

Special tools
Use the recommended special tools to pro-
tect parts from damage. Use the right tool in
the right manner—do not improvise.
Tightening torques
Follow the tightening torque specifications
provided throughout the manual. When tight-
ening nuts, bolts, and screws, tighten the
large sizes first, and tighten fasteners starting
in the center and moving outward.
Non-reusable parts
Always use new gaskets, seals, O-rings, cot-
ter pins, circlips, etc., when installing or
assembling parts.

Disassembly and assembly

dirt during disassembly.
