General Description
C: CAUTION
Wear work clothing, including a cap, protective
goggles, and protective shoes during operation.
Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro-
tect them from dust and dirt.
Until the oil pan is installed, do not place with the
inside of oil pan facing up to prevent foreign matter
from entering the valve body.
Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
When disassembling the case and other light al-
loy parts, use a plastic hammer to force it apart. Do
not pry it apart with a screwdriver or other tool.
Be careful not to burn yourself, because each
part on the vehicle is hot after running.
Use SUBARU genuine gear oil, grease etc. or
the equivalent. Do not mix gear oil, grease etc. with
that of another grade or from other manufacturers.
Be sure to tighten fasteners including bolts and
nuts to the specified torque.
Place shop jacks or rigid racks at the specified
points.
Apply gear oil or ATF onto sliding or revolution
surfaces before installation.
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 vice, place cushion-
ing material such as wood blocks, aluminum plate,
or shop cloth between the part and the vice.
Avoid damaging the mating surface of the case.
Before applying sealant, completely remove the
old seal.
