VANE PUMP(for 1VD-FTV) INSPECTION

PROCEDURE


  1. CHECK OIL CLEARANCE BETWEEN VANE PUMP SHAFT AND VANE PUMP REAR HOUSING BUSHING


    1. A01WT2ZE02

      Using a micrometer, measure the outer diameter [a] of the shaft.

    2. Using a vernier caliper, measure the inner diameter [b] of the rear housing bush.

    3. Calculate the oil clearance.

      Oil clearance = Inner diameter of the bush [b] - Outer diameter of the shaft [a]

      Maximum oil clearance
      0.08 mm (0.00315 in.)

      If the oil clearance is more than the maximum, replace the vane pump assembly.

  2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES


    1. A01WQPSE04

      *a Thickness

      Using a micrometer, measure the thickness of the 10 vane pump plates.

      Standard thickness
      1.405 to 1.411 mm (0.0553 to 0.0556 in.)

      If the thickness is not as specified, replace the vane pump assembly.

    2. A01WWQZ

      Using a feeler gauge, measure the clearance between the side face of the rotor groove and the plate.

      Maximum clearance
      0.03 mm (0.00118 in.)

      If the clearance is more than the maximum, replace the vane pump assembly.
