  Note
  
  Be careful not to damage the lip of the oil seal.
REMOVE STATOR SHAFT ASSEMBLY

INSPECT CLEARANCE OF FRONT OIL PUMP BODY AND GEAR SUB-ASSEMBLY

A006SU0

Push the driven gear to one side of the oil pump body.
Using a feeler gauge, measure the clearance.

Standard clearance

0.08 to 0.15 mm (0.00315 to 0.00590 in.)

Maximum clearance

0.15 mm (0.00590 in.)

If the clearance is more than the maximum, replace the front oil pump body and gear sub-assembly.

A006VK0

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

Standard side clearance
0.025 to 0.04 mm (0.000984 to 0.00157 in.)
Maximum side clearance
0.04 mm (0.00157 in.)

If the clearance is more than the maximum, replace the front oil pump body and gear sub-assembly.
