Continuously Variable Transaxle (CVT) (H4DO): General Description: 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.
