C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Until the oil pan is removed, do not place with the oil pan side facing up to prevent foreign matter from en-
tering the valve body.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, dis-
assembly and replacement.
•When disassembling the case and other light alloy parts, disassemble them by slightly tapping with a plas-
tic hammer. Do not pry apart with screwdrivers or other tools.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Use SUBARU genuine gear oil, grease or the equivalent. Do not mix them with that of another grade or
from other manufacturers.
•Be sure to tighten 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 damaged snap rings with new parts.
•Before installing O-rings or oil seals, apply sufficient amount of ATF fluid to avoid damage and deforma-
tion.
•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 cushioning 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 remove the old seal.
