E: INSPECTION
1. FRONT BRAKE
Check the following items.
- Drive plate facing for wear or damage
- Snap ring for wear, return spring for damage, and retainer for damage
- Piston for damage
- D-ring for damage
2. OIL PUMP
Check the following items.
- Oil pump cover and oil seal for breakage or damage

1) Check the seal ring and oil seal for breaks and damage.
2) Check other parts for dents or faults.
3) Oil pump rotor assembly selection
- Tip clearance
Install the inner rotor and outer rotor to oil pump housing. With rotor gears facing each other, measure the crest-to-crest clearance.
Tip clearance: 0.02 - 0.15 mm (0.0008 - 0.0059 in)
- Thickness gauge
- Inner rotor
- Outer rotor
- Side clearance
Set a depth gauge to oil pump housing, then measure the oil pump housing-to-rotor clearance.
Side clearance: 0.02 - 0.045 mm (0.0008 - 0.0018 in)
- Depth gauge
- Inner rotor
- Outer rotor
- If the tip and/or side clearance are not within the specification, replace the rotor assembly.
Check the total end play and adjust it to be within specifications. <Ref. to 5AT-103, ADJUSTMENT, AT Main Case.>
