(b) Using a hammer and brass bar, remove the oil pump by
carefully tapping the oil pump body.
(c) Remove the 2 O±rings from the cylinder block.
COMPONENTS FOR DISASSEMBLY AND
ASSEMBLY
OIL PUMP DISASSEMBLY
Assembly is in the reverse order of disassembly.
1. REMOVE RELIEF VALVE
(a) Slighty mount the pump body in a vise.
NOTICE: Be careful not to damage the pump body.
(b) Remove the plug, gasket (2JZ±GE), O±ring (2JZ±GTE),
compression spring and relief valve. EG±370

Page 1223 of 2543
INSTALLATION HINT:
Use a new gasket (2JZ±GE) or O±ring (2JZ±GTE).
Torque:
2JZ±GE
49 NVm (500 kgfVcm, 36 ftVlbf)
2JZ±GTE
29 NVm (300 kgfVcm, 22 ftVlbf)
2. REMOVE DRIVE AND DRIVEN ROTORS
Remove the 10 screws, pump body cover, the drive and driv-
en rotors.
Torque: 10 NVm (105 kgfVcm, 8.0 ftVlbf)
ASSEMBLY HINT: Place the drive and driven rotors into the
oil pump body with the mark facing upward.
OIL PUMP INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole under its own weight.
If it doesn't, replace the relief valve. If necessary, replace the
oil pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS
A. Place drive and driven rotors into oil pump body
ASSEMBLY HINT: Place the drive and driven rotors into the
oil pump body with the mark facing upward.

B. Inspect rotor tip clearance
Using a feeler gauge, measure the clearance between the
drive and driven rotors.
Standard tip clearance:
2JZ±GE
0.310±0.490 mm (0.0122±0.0193 in.)
2JZ±GTE
0.056±0.326 mm (0.0022±0.0128 in.)
Maximum tip clearance:
2JZ±GE
0.53 mm (0.0209 in.)
2JZ±GTE
0.40 mm (0.0157 in.)
If the tip clearance is greater than maximum, replace the ro-
tors as a set.
C. 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.
D. Inspect rotor side clearance
Using a feeler gauge and precision straight edge, measure
the clearance between the rotors and precision straight
edge.
Standard side clearance:
2JZ±GE
0.030±0.090 mm (0.0012±0.0035 in.)
2JZ±GTE
0.020±0.065 mm (0.0007±0.0026 in.)
