General Description
C: CAUTION
Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
Remove contamination including dirt and corro-
sion before removal, installation, and disassembly.
Keep the disassembled parts in order and pro-
tect them from dust or dirt.
Until the oil pan is removed, do not place with the
oil pan side 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 your hands, 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 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 gear oil 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 shop cloth between the part and the vis e.
Avoid damaging the mating surface of the case.
Before applying sealant, completely remove the
old seal.
