Usage:
START BY:
a. remove timing gear cover
1. Remove the bolt and retainer (1) that hold guide (2) for the relief valve. Remove guide (2), the spring and the plunger from the timing gear cover.
2. Remove bolts (3) and oil pump cover (4).
3. Remove inner rotor (5) and outer rotor (6) from the timing gear cover.
4. Remove bearing (7) and shaft (8) from the timing gear cover if a replacement is necessary.
Install Oil Pump And Relief Valve
1. Install shaft (2) in the timing gear cover until dimension (Y) is 21.84 ± 0.25 mm (.860 ± .010 in.).
2. Use tooling (B) to install bearing (1) in the timing gear cover until dimension (X) is 8.74 ± 0.25 mm (.344 ± .010 in.). Also, the bearing joint must be located 45° ± 30° from centerline (Z).
3. After installation of the bearing in the timing gear cover, check the inside diameter. The inside diameter (W) of the bearing must be 71.22 ± 0.05 (2.804 ± .002 in.).
| NOTICE |
|---|
When the outer and inner rotors are replaced, they must be replaced as a set. |
4. Install outer rotor (4) and inner rotor (3) in the timing gear cover.
5. Check the clearance between the inner and outer rotors with feeler gauge (5) as shown. The clearance must be 0.05 to 0.20 mm (.002 to .008 in.). The maximum permissible clearance must not be more than 0.28 mm (.011 in.).
6. Put cover (6) in position on the timing gear cover, and install the bolts that hold it in place.
7. Check the oil pump end clearance with feeler gauge (5). The maximum permissible end clearance must not be more than 0.120 mm (.0047 in.). If the end clearance is more, replace the inner and outer rotors as a set.
8. Install plunger (9), spring (8) and guide (7) in the timing gear cover. Use tooling (C) to tighten guide (7) to a torque of 41 ± 7 N·m (30 ± 5 lb.ft.).
9. Install the retainer and bolt that holds the guide in the timing gear cover.
