sion before removal, installation or disassembly.
• Keep the disassembled parts in order and pro-
tect them from dust and dirt.
• Do not place the oil pan with its inner side facing
upward until it is installed so as to prevent foreign
matter intrusion into valve body.
• Before removal, installation or disassembly, be

moval, installation, disassembly and replacement.
• When disassembling the case and other light al-
loy parts, use a plastic hammer to open the case.
Do not pry it apart with a screwdriver or other tool.
• Be careful not to burn yourself, because each

the equivalent. Do not mix gear oil, grease etc. with
that of another grade or from other manufacturers.

• Be sure to tighten bolts and nuts to the specified
torque.
• Place a lift, a shop jack or a rigid rack at the spec-
ified position.
• Before installation, apply gear oil or ATF onto
sliding or revolution surface according to purpose
of part.
• Replace deformed or otherwise damaged snap
rings with new ones.
• Before installing O-rings or oil seals, apply suffi-
cient amount of ATF to avoid damage and defor-
mation.
• Be careful not to incorrectly install or fail to install
O-rings, snap rings and other such parts.
• Before securing a part on a vise, place cushion-
ing material such as wood blocks, aluminum plate,
or cloth between the part and the vise.
• Avoid damaging the mating surface of the case.
• Before applying liquid gasket, completely re-
move the old seal.
