Assembly Procedure

1.  Assemble new seal rings using the following procedure:

Caution
•  If a seal ring is reused it could cause ATF leakage, therefore use a new seal ring.
Note
•  Seal ring size: Outer diameter approx. 52.5 mm {2.07 in}, thickness approx. 1.5 mm {0.059 in}
(1)  Apply ATF (ATF FZ) to the new seal rings.
(2)  Assemble the new seal rings.

2.  Assemble the outer rotor using the following procedure:

(1)  Apply ATF (ATF FZ) to the outer rotor.
(2)  Assemble the outer rotor.
Note
•  Assemble so that the outer rotor marking is facing the oil pump housing.

4.  Assemble a new oil seal using the following procedure:

Caution
•  If an oil seal is reused it could cause ATF leakage, therefore use a new oil seal.
(1)  Apply ATF (ATF FZ) to the engagement area of the new oil seal and oil pump cover.
(2)  Apply ATF (ATF FZ) to the lip of the new oil seal.
(3)  Assemble the new oil seal to the position shown in the figure using the SST.
