INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. CHECK OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and caliper gauge, measure the oil clear-
ance.
5S±FE and 1MZ±FE Engines:
Standard clearance:
0.03 ± 0.05 mm (0.0012 ± 0.0020 in.)
Maximum clearance: 0.07 mm (0.0028 in.)
If it is more than the maximum, replace the front housing and
vane pump shaft.
2. INSPECT VANE PUMP ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness and
length of the plates.
5S±FE and 1MZ±FE Engines:
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.397 mm (0.0550 in.)
Minimum length: 14.991 mm (0.5902 In.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
5S±FE and 1MZ±FE Engines:
Maximum clearance: 0.035 mm (0.0014 in.)
If it is more than the maximum, replace the plate and/or rotor
with one having the same mark stamped on the cam ring.

4. INSPECT SPRING
Using a calipers, measure the free length of the spring.
5S±FE and 1MZ±FE Engines:
Minimum free length: 32.3 mm (1.272 in.)
If it is not within the specification, replace the spring.
5. IF NECESSARY, REPLACE OIL SEAL
(a) Using a screwdriver with vinyl tape wound around its tip,
remove the oil seal.
NOTICE:
Be careful not to damage the front housing.
(b) Coat a new oil seal lip with power steering fluid.
(c) Using SST, press in the oil seal.
SST 09950±60010 (09951±00330),
09950±70010 (09951±07100)
NOTICE:
Make sure to install the oil seal facing the correct direction.
