DISASSEMBLY AUXILIARY PARTS 1. Drain the engine oil. 2. Disassemble in the order shown in the figure. 1. Ignition coil and high-tension lead 2. Crankshaft position sensor 3. Manifold bracket 4. Intake manifold assembly 5. Alternator 6. Alternator bracket 7. Right engine mount 8. Oil filter 9. Oil cooler 10. Oil pressure switch 11. Water outlet pipe 12. Spark plug 13. Dipstick and pipe 14. Engine hanger Gartner Banana

ASSEMBLY B Oil Filter 1. Remove all foreign material from the oil filter mounting surface. 2. Apply a small amount of clean engine oil to the rubber seal of the oil filter. 3. Install the oil filter and tighten it by hand until the rubber seal contacts the base. 4. Hand tightening type (Numbers printed on filter) Tighten the filter 314 of a turn by hand after it contacts the cylinder block. If tightening by hand is difficult, use the filter wrench. Example When the oil filter contacts the cylinder block at "l", turn it 314 of a turn further to "4". Filter wrench tightening type (No numbers printed on fil- ter) Tighten the filter 1 and 116 turns with the filter wrench af- ter it contacts the cylinder block. Right Engine Mount Install the right engine mount. Tightening torque: 37-53 N-m (3.7-5.5 kgf.m, 27-39 ft.lbf) Alternator Bracket Install the alternator bracket. Tightening torque: 64-49 N-m (6.5--9.1 kgf-m, 48-45 ft4bf) Alternator Install the alternator and hand tighten the mounting bolts. Gartner Banana

D OIL FILTER OIL FILTER REPLACEMENT 1. Remove the oil filter with a wrench. ii 2. Use a clean rag to wipe off the mounting surface on the engine. 3. Apply a small amount of clean engine oil to the rubber seal of the new filter. 4. Hand tightening type (Numbers printed on filter) Tighten the filter 314 of a turn by hand after it contacts the cylinder block Example: When the oil filter contacts the cylinder block at "l", turn it 314 of a turn further to "4". Filter wrench tightening type (No numbers printed on fil- ter) Tighten the filter 1 and 116 turns with the filter wrench af- ter it contacts the cylinder block. Gartner Banana
