PLACE DRIVE AND DRIVEN ROTORS INTO OIL PUMP BODY (a) Place drive and driven rotors into oil pump body HINT: Place the drive and driven rotors into the oil pump body with the mark facing upward. P02186 3. INSPECT ROTOR TIP CLEARANCE Using a feeler gauge, measure the clearance between the drive and driven rotors. Standard tip clearance: 2JZ-GE: 0.060 - 0.240 mm (0.0024 - 0.0094 in.) 2JZ-GTE: 0.056 - 0.326 mm (0.0022 - 0.0128 in.) Maximum tip clearance: 2JZ-GE: 0.30 mm (0.0118 in.) 2JZ-GTE: 0.40 mm (0.0157 in.) If the tip clearance is greater than maximum, replace the rotors as a set. P02294 4. INSPECT ROTOR BODY CLEARANCE Using a feeler gauge, measure the clearance between the driven rotor and pump body. Standard body clearance: 2JZ-GE: 0.100 - 0.175 mm (0.0039 - 0.0069 in.) 2JZ-GTE: 0.080 - 0.135 mm (0.0031 - 0.0053 in.) Maximum body clearance: 2JZ-GE: 0.20 mm (0.0079 in.) 2JZ-GTE: 0.16 mm (0.0063 in.) If the body clearance is greater than maximum, replace the rotors as a set. If necessary, replace the oil pump assembly. P02157 1997 SUPRA (RM502U) Author : Date : 1460
