5.Remove oil pan and oil pump pick up. It may be necessary to remove transaxle inspection cover.
6.Remove accessory drive belt as follows:
a.Remove right front wheel and tire assembly, then inner splash shield.
b.Release belt tension by rotating tensioner clockwise, then remove accessory drive belt.
7.Remove A/C compressor and position aside.
8.Remove A/C compressor mounting bracket.

10.Remove idler pulley from engine bracket, then engine bracket, Fig. 2.
11.Remove cam sensor from chain case cover, then chain case cover, Fig. 3.
TIMING CHAIN INSPECTION
1.Place a scale next to timing chain so chain movement can be measured.
2.Install a torque wrench and socket over camshaft sprocket, then apply torque in direction of crankshaft rotation to take up chain slack. Apply 30 ft. lbs. of torque with cylinder heads installed or 15 ft. lbs. of torque with cylinder heads removed. With torque applied to camshaft sprocket bolt, crankshaft should not move. It may be necessary to block crankshaft to prevent rotation.
3.Holding a scale with dimension reading even with edge of a chain link, apply specified torque in reverse direction and note amount of chain movement, Fig. 4.
4.If timing chain movement exceeds 1/8 inch, replace chain.
TIMING CHAIN REPLACEMENT
1.Remove camshaft sprocket attaching cup washer, then remove timing chain with crankshaft and camshaft sprockets.
2.Install new timing chain around both sprockets.
3.Turn crankshaft and camshaft to align keyway locations in both sprockets.
4.Lift sprocket and chain, keeping sprockets tight against chain in position described.
5.Slide both sprockets with chain evenly over their respective shafts, then use a straightedge to check alignment of timing marks, Fig. 5.
6.Install cup washer and camshaft sprocket bolt. Tighten bolt to specifications.
7.Check camshaft endplay. Endplay should measure .005-.012 inch with a new thrust plate or up to .012 inch with a used thrust plate. If camshaft endplay is not as specified, replace thrust plate.
8.Install timing chain cover.
TIMING CHAIN COVER INSTALLATION & OIL SEAL REPLACEMENT
1.Ensure mating surfaces of chain case cover are clean and free of burrs. Crankshaft oil seal must be removed to ensure correct oil pump engagement.
2.Remove crankshaft oil seal using crankshaft removal tool No. C-4991, or equivalent, as shown in Fig. 6. Use caution not to damage crankshaft seal surface of cover.
3.Install a new cover gasket and new O-rings, Fig. 7.
4.Rotate crankshaft so oil pump drive flats are vertical.
5.Position oil pump inner rotor so mating flats are in same position as crankshaft drive flats, Fig. 7.
6.Install cover onto crankshaft. Ensure oil pump is correctly engaged on crankshaft or severe damage may result.
7.Install chain case cover screws and tighten to specifications.
8.Install crankshaft oil seal as follows:
a.Position seal into opening with seal spring towards inside of engine.
b.Install seal until flush with cover using seal crankshaft seal installing tool No. C-4992, or equivalent, Fig. 8.
9.Install crankshaft pulley using thrust bearing/washer plate tool No. L-4524, or equivalent and a 5.9 inch screw, Fig. 9. Tighten crankshaft pulley bolt to specifications.
10.Install engine bracket, Fig. 2 and tighten attaching screws to specifications.
11.Install idler pulley on engine bracket.
12.Install cam sensor.
13.Install A/C compressor mounting bracket, then A/C compressor.
14.Install accessory drive belt.
15.Install right front inner splash shield, then wheel and tire assembly.
16.Install oil pump pickup, oil pan and transaxle inspection cover, if removed.
17.Install engine mount.
18.Fill crankcase with oil to proper level.
19.Fill cooling system.
20.Connect battery ground cable.
