  6. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01FECR

      Using a caliper gauge, measure the inside diameter of the oil pump body bushing.

      Maximum inside diameter
      38.138 mm (1.50 in.)

      If the inside diameter is more than the maximum inside diameter, replace the front oil pump body assembly.

  7. INSPECT STATOR SHAFT ASSEMBLY


    1. A01FIVZ

      Using a caliper gauge, measure the inside diameter of the stator shaft bushing.

      Maximum inside diameter
      Front side
      21.527 mm (0.848 in.)
      Rear side
      32.03 mm (1.26 in.)

      If the inside diameter is more than the maximum inside diameter, replace the stator shaft assembly.

  8. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A01FF2N

      Push the front oil pump driven gear to one side of the front oil pump body sub-assembly.

    2. Using a feeler gauge, measure the clearance.

      Standard body clearance
      0.10 to 0.17 mm (0.00394 to 0.00669 in.)

      If the body clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    3. A01FG1K

      Using a feeler gauge, measure the clearance between the front oil pump driven gear teeth and the front oil pump drive gear teeth.

      Standard tip clearance
      0.070 to 0.150 mm (0.00276 to 0.00590 in.)

      If the tip clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    4. A01FHMG

      Using a steel straightedge and a feeler gauge, measure the side clearance of both gears.

      Standard side clearance
      0.03 to 0.05 mm (0.00118 to 0.00196 in.)

    5. There are 7 different thicknesses for the front oil pump drive gears and front oil pump driven gears.

      Front Oil Pump Drive Gear Thickness
      Part No. Mark Thickness
      35321-50010 0 10.736 to 10.742 mm (0.42268 to 0.42291 in.)
      35321-50020 1 10.743 to 10.749 mm (0.42296 to 0.42318 in.)
      35321-50030 2 10.750 to 10.756 mm (0.42323 to 0.42346 in.)
      35321-50040 3 10.757 to 10.763 mm (0.42351 to 0.42373 in.)
      35321-50050 4 10.764 to 10.770 mm (0.42378 to 0.42401 in.)
      35321-50060 5 10.771 to 10.777 mm (0.42406 to 0.42429 in.)
      35321-50070 6 10.778 to 10.784 mm (0.42433 to 0.42456 in.)
      Front Oil Pump Driven Gear Thickness
      Part No. Mark Thickness
      35322-50010 0 10.736 to 10.742 mm (0.42268 to 0.42291 in.)
      35322-50020 1 10.743 to 10.749 mm (0.42296 to 0.42318 in.)
      35322-50030 2 10.750 to 10.756 mm (0.42323 to 0.42346 in.)
      35322-50040 3 10.757 to 10.763 mm (0.42351 to 0.42373 in.)
      35322-50050 4 10.764 to 10.770 mm (0.42378 to 0.42401 in.)
      35322-50060 5 10.771 to 10.777 mm (0.42406 to 0.42429 in.)
      35322-50070 6 10.778 to 10.784 mm (0.42433 to 0.42456 in.)

      If the side clearance is more than the standard thickness, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.
