1. Remove the oil filter with the special tool.
2. Inspect the threads (A) and rubber seal (B) on the new filter. Wipe off the seat on the engine block, then apply a light coat of new engine oil to the filter rubber seal. Use only filters with a built-in bypass system.
3. Install the oil filter by hand.
4. After the rubber seal seats, tighten the oil filter clockwise with the special tool. Tighten: 7/8 Turn Clockwise. Tightening Torque: 22 N.m (2.2 kgf.m, 16 lbf.ft)
5. If eight numbers (1 to 8) are printed around the outside of the filter, use the following procedure to tighten the filter. Spin the filter on until its seal lightly seats against the engine oil cooler, and note which number is at the bottom. Tighten the filter by turning it clockwise seven numbers from the one you noted. For example, if number 2 is at the bottom when the seal is lightly seated, tighten the filter until the number 1 comes around the bottom.
6. After installation, fill the engine with the recommended oil up to the specified level, run the engine for more than 3 minutes, then check for oil leakage.

Scheme 10

1. Remove the oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-221324-S19981930532006022400000) ).
2. Disconnect the water bypass hoses.
3. Remove the oil cooler center bolt (A) and oil cooler (B).
4. Apply new engine oil to new O-ring (C).
5. Install the oil cooler. Tighten the oil cooler center bolt to the engine block.
6. Connect the water bypass hoses.
7. Install the new oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-221324-S19981930532006022400000) )

Scheme 11

1. Remove the crankshaft from the engine block (see «CRANKSHAFT AND PISTON REMOVAL»(ref-221323-S38652883282006022400000) ).
2. Remove the oil jet bolt (A) and oil jet (B).
3. Carefully install the oil jet and tighten the oil jet bolt.
4. Install the crankshaft (see «CRANKSHAFT INSTALLATION»(ref-221323-S20618061052006022400000) ).

Scheme 12

1. Remove the oil jet, and inspect it as follows. Make sure that a 1.5 mm (0.059 in.) diameter drill will go through the nozzle hole (A) (1.6 mm (0.062 in.) diameter). Insert the end of a 1.1 mm (0.043 in.) drill into the oil intake (1.2 mm (0.047 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 2 , 28 psi) to unseat the check ball. NOTE: Replace the oil jet assembly if the nozzle is damaged or bent.
2. The mounting torque is critical. Be very precise when installing the oil jet. Torque: 16 N.m (1.6 kgf.m, 12 lbf.ft)

1. Remove the cam chain (see «CAM CHAIN REMOVAL»(ref-221322-S39532039912006022400000) ).
2. Remove the oil pump chain tensioner.
3. Remove the baffle plate.
4. Remove the three bolts securing the oil pump.
5. Remove the oil pump (A), oil pump chain (B), and crankshaft sprocket (C).

Scheme 20

1. Remove the bolts from the pump housing, then separate the pump housing and 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 assembly. Inner Rotor-to-Outer Rotor Radial Clearance Standard (New): 0.02-0.14 mm (0.001-0.006 in.) Service Limit: 0.20 mm (0.008 in.)
3. Check the housing-to-rotor axial clearance between the rotors (A) and pump housing (B). If the housing-to-rotor axial clearance exceeds the service limit, replace the oil pump assembly. Housing-to-Rotor Axial Clearance Standard (New): 0.02-0.07 mm (0.001-0.003 in.) Service Limit: 0.12 mm (0.005 in.)
4. Check the housing-to-outer rotor radial clearance between the outer rotor (A) and pump housing (B). If the housing-to-outer rotor radial clearance exceeds the service limit, replace the oil pump assembly. Housing-to-Outer Rotor Radial Clearance Standard (New): 0.15-0.21 mm (0.006-0.008 in.) Service Limit: 0.23 mm (0.009 in.)
5. Inspect both rotors and the pump housing for scoring or other damage. Replace the oil pump assembly, if necessary.
6. Check that the oil pump turns freely.

1. Squeeze the new oil pump chain tensioner (A), then install the set clip (B) on it as shown below. NOTE: The set clip is supplied with the oil pump chain tensioner.
2. Install the crankshaft sprocket (A), oil pump chain (B), and oil pump (C).
3. Tighten the bolts on the oil pump.
4. Install the baffle plate.
5. Set the crankshaft sprocket so that the No. 1 piston is at top dead center (TDC). Align the key (A) on the sprocket and crankshaft with the pointer (B) on the engine block.
6. Move the cam chain so that the colored piece (A) aligns with the punched mark (B) on the crankshaft sprocket.
7. Install the oil pump chain guide (A) and oil pump chain tensioner (B) with the seat clip (C).
8. Remove the set clip from the oil pump chain tensioner.
9. Install the cam chain (see «CAM CHAIN INSTALLATION»(ref-221322-S34674341402006022400000) ).
