E: INSPECTION

1. FRONT BRAKE

Check the following items.
• Drive plate facing for wear and 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 dam-
age
• Oil pump body for scratch 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

(1) 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)

(2) Side clearance
Set a depth gauge to oil pump housing, then
measure the oil pump housing-to-rotor clear-
ance.

Side clearance:

0.02 — 0.045 mm (0.0008 — 0.0018 in)

(3) If the depth and/or side clearance are not
within the specification, replace the rotor as-
sembly.

Measure the total end play and adjust it to be
within specifications. <Ref. to 5AT-107, AD-
JUSTMENT, AT Main Case.>
