Subaru Legacy BN/BS (2015-2019) Service Manual: Caution

• Remove contamination including dirt and corrosion before removal, installation or disassembly.

• Keep the disassembled parts in order and protect them from dust and dirt.

• Do not place the valve cover with its inner side facing up until it is installed, to prevent intrusion of foreign matter into the control valve body.

• Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.

• When disassembling the case and other light alloy parts, use a plastic hammer to force it apart. Do not pry apart with screwdrivers or other tools.

• Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.

• Use SUBARU genuine CVTF and recommended grease. Do not mix CVTF, grease etc. of different grades or manufacturers.

• Be sure to tighten bolts and nuts to the specified torque.

• Apply CVTF onto sliding or revolving surfaces before installation.

• Replace deformed or damaged snap rings with new parts.

• Before installing O-rings or oil seals, apply sufficient amount of CVTF or gear oil to appropriate locations in order to avoid damage and deformation.

• 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 liquid gasket.

• After removing the sensors, breather hose and plugs, plug the holes to avoid foreign materials intruding as necessary.

• During disassembly or assembly, be sure to use nylon gloves or paper towels. Do not use cloth gloves or waste cloth.

• Be careful of handling the oil seal, O-ring and gasket. If the contact surface of them is damaged, oil leakage may occur.

• When pressing-in the oil seal, make sure that the oil seal lip portion and outer surface are not damaged or tilted.

• When replacing the taper roller bearing, replace the outer race and inner race as a set.

• When replacing the hypoid gear, replace the hypoid gear and drive pinion shaft as a set.

• Replace the bolts if the seating surface or the thread surface is excessively rusted.
