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.
• Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
• 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 onto sliding or revolution surfaces
before installation.
• Before installing O-rings or snap rings, apply suf-
ficient amount of gear oil to avoid damage and de-
formation.
• 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.
