• Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of

the unit, preventing them from entering into the unit during disassembly or assembly.

• Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them

with a new ones if necessary.

• Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-

ening sequence is specified, observe it.

• Clean and flush the parts sufficiently and blow-dry them.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,

and foreign materials from the application and mounting surfaces.

• Always use shop paper for cleaning the inside of components.
• Never use cotton gloves or shop rags to prevent entering of lint.
