INSPECTION
Valve Spring
Measure free length and outer diameter of each valve spring.
Also check for damage or deformation. Refer to AT- 5 3 0 , "
SER-
VICE DATA AND SPECIFICATIONS (SDS)" .
Replace valve springs if deformed or fatigued.
Control Valves
Check sliding surfaces of valves, sleeves and plugs.
ASSEMBLY
CAUTION:
Apply ATF to all components before installation.
Lay control valve body down when installing valves. Do not
stand control valve body upright.
Lubricate control valve body and all valves with ATF. Install con-
trol 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.
