Title: 3UR-FBE LUBRICATION: OIL PUMP: INSPECTION; 2015 MY Tundra [08/2014 - ]
INSPECTION
1. INSPECT OIL PUMP RELIEF VALVE
(a) Coat the relief valve with engine oil.
(b) Check that the relief valve falls smoothly into the valve hole by its own weight.
If the relief valve is not as specified, replace it. If necessary, replace the timing chain cover
sub-assembly.
2. INSPECT OIL PUMP ROTOR SET
(a) Install the rotors to the timing chain cover with the rotors'
marks facing outward. Check that the rotors revolve
smoothly.
(b) Check the tip clearance.
(1) Using a feeler gauge, measure the clearance between the
drive and driven rotor tips, as shown in the illustration.
Standard tip clearance:
0.180 to 0.300 mm (0.00709 to 0.0118 in.)
Maximum tip clearance:
0.300 mm (0.0118 in.)
If the tip clearance is more than the maximum, replace
the timing chain cover sub-assembly.

(1) Using a feeler gauge, measure the clearance between the
timing chain cover and driven rotor as shown in the
illustration.
Standard body clearance:
0.175 to 0.250 mm (0.00689 to 0.00984 in.)
Maximum body clearance:
0.250 mm (0.00984 in.)
