Fluid Pump: Testing and Inspection

1. Install the ATF pump gears and ATF pump driven gear shaft in the main valve body.

NOTE:
- Lubricate all parts with ATF during inspecting.
- Install the ATF pump driven gear with its grooved and chamfered side facing up as shown.





2. Measure the side clearance of the ATF pump drive and driven gears.
- ATF Pump Gears Side (Radial) Clearance: Standard (New):
Drive gear: 0.210 - 0.265 mm (0.0083 - 0.0104 inch)
Driven gear: 0.070 - 0.125 mm (0.0028 - 0.0049 inch)





3. Remove the ATF pump driven gear shaft, and measure the thrust clearance of the ATF pump driven gear-to-main valve body.
- ATF pump Drive/Driven Gear thrust (Axial) Clearance:
Standard (New): 0.03 - 0.05 mm (0.001 - 0.002 inch)
Service Limit: 0.07 mm (0.003 inch)
