c. Place mating surface of valve body face down, and remove internal parts.
CAUTION:
• If a valve is hard to remove, place valve body face downand lightly tap it with a soft hammer.
• Be careful not to drop or damage valves and sleeves.
INSPECTION
Va l v e Sp r i n g s
• Check each valve spring for damage or deformation. Also measure
free length and outer diameter. Refer to AT-375, "
Control Valves".
• Replace valve springs if deformed or fatigued.
Control Valves
Check sliding surfaces of valves, sleeves and plugs. Replace if necessary.
ASSEMBLY
CAUTION:
• Apply ATF to all componen ts before installation.
• Lay control valve body down wh en installing valves. Do not
stand control valve body upright.
Lubricate control valve body and all valves with ATF. Install control
valves by sliding them carefully into their bores.
CAUTION:
• Install each control valve one by one.
• Install control valves after checking, because some of them are similar.
• Be careful not to scratch or damage valve body.
