1. Remove the oil filter (see page 8-9).
2. Remove the oil filter feed pipe.
3. Install two 20 x 1.5 mm nuts (A) onto the new oil
filter feed pipe. Hold the nut with a wrench, then
tighten the other nut.
4. Tighten the oil filter feed pipe to the block to
49 N·m (5.0 kgf·m, 36 lbf·ft), then remove the nuts
from the oil filter feed pipe.
1. Remove the oil filter (see page 8-9).
2. Remove the oil cooler bypass hoses (A) and oil
cooler center bolt (B), then remove the oil cooler (C).
3. Install the oil cooler using a new O-ring (D). Tighten
the oil cooler center bolt to 74 N·m (7.5 kgf·m,
54 lbf·ft).

1. Remove the oil jet, and inspect it as follows.
• Make sure that a 1.1 mm (0.04 in.) diameter drill
will go through the nozzle hole (A) (1.2 mm
(0.05 in.) diameter).
• Insert the other end of a 1.1 mm (0.04 in.) drill
into the oil intake (1.2 mm (0.05 in.) diameter).
Make sure the check ball (B) moves smoothly and
has a stroke of approximately 4.0 mm (0.16 in.).
• Check the oil jet operation with an air nozzle. It
should take at least 200 kPa (2.0 kgf/cm , 28 psi)
to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzle is
damaged or bent.
2. Carefully install the oil jet. The mounting torque is
critical.

1. Remove the oil pan (see page 7-11).
2. Remove and discard the oil pump chain tensioner.
3. Remove the oil pump.
1. Remove the pump cover.
2. Check the inner-to-outer rotor radial clearance
between the inner rotor (A) and outer rotor (B). If
the inner-to-outer rotor radial clearance exceeds
the service limit, replace the oil pump.
3. Check the housing-to-rotor axial clearance between
the rotor (A) and pump housing (B). If the housing-
to-rotor axial clearance exceeds the service limit,
replace the oil pump.
