Corolla Wagon L4-107.5 1762cc 1.8L DOHC (7A-FE) (1993)
2. INSPECT DRIVE AND DRIVEN ROTORS
A. Inspect rotor body clearance
Using a thickness gauge, measure the clearance between the driven rotor and body.
Standard body clearance: 0.080 - 0.180 mm (0.0031 - 0.0071 in.)
Maximum body clearance: 0.20 mm (0.0079 in.)
If the body clearance is greater than maximum, re place the rotors as a set.
If necessary, replace the oil pump assembly.
B. Inspect rotor tip clearance
Using a thickness gauge, measure the clearance between the drive and driven rotor tips.
Standard tip clearance: 0.025 - 0.085 mm (0.0010 - 0.0033 in.)
Maximum tip clearance: 0.35 mm (0.0138 in.)
If the tip clearance is greater than maximum1 replace the rotors as a set.
C. Inspect rotor side clearance
Using a thickness gauge and precision straight edge, measure the clearance between the rotors and precision straight edge.
Standard side clearance: 0.025 - 0.085 mm (0.0010 - 0.0033 in.)
Maximum side clearance: 0.10 mm (0.0039 in.)
If the side clearance is greater than maximum, replace the rotors as a set.
If necessary, replace the oil pump assembly.
