Start By:a. remove transmission oil pump and pump drive gear 1. Remove O-ring seal (2) from cover (3), bolts (1) and cover (3) from the pump body. 2. Remove bearings (4) from cover (3). 3. Remove drive gear (7), driven gear (6) and O-ring seal (5) from the pump body. 4. Remove bearings (8) from pump body (9). 5. Remove spiral lockring (10), shaft (11) and bearing (12) from gear (13). The following are assembly steps of the transmission oil pump and drive gear.6. Make sure all of the parts of the transmission oil pump and pump drive gear are clean. Put clean oil on all the parts of the pump and gear. Inspect all parts for damage and make replacements if needed.7. Install bearing (12) and shaft (11) in gear (13) with spiral lockring (10) to hold the bearing in place.
Make sure the joint in both bearings (8) are in the correct location. The location of the joint is an angle of 30° 15° from the center line of the two bearing bores in the direction of groove (14) on surface (15).
8. Install two bearings (8) into pump body (9) with tooling (A) and a press. The distance from the top of the bearing to surface (15) after assembly is 1.50 0.25 mm (.059 .010 in.).9. Install O-ring seal (5), driven gear (6) and drive gear (7) in pump body (9).
