10. Remove oil pan. Refer to Oil Pan, Engine.
When remove mounting member, use lifting device instead of engine support jack.
11. Remove engine front torque bush, rear mounting and rear mounting No.2 bracket.





12. With hoses connected, detach A/C compressor from compressor bracket.

NOTE: Suspend removed A/C compressor at a place free from any possible damage during removal and installation of timing chain cover.

13. Remove A/C compressor bracket.
14. Disconnect P/S oil tank from body.
15. Disconnect electric lead wire couplers (heated oxygen sensor and A/C magnet clutch) and release clamps.





16. Remove engine RH mounting.





17. Using lifting device, raise engine enough to allow removal of water pump pulley, generator belt idler pulley, generator belt tensioner and remove them.

CAUTION:
^ Do not loosen generator belt tensioner bolt and disassemble generator belt tensioner assembly, as It may spoil its original performance.
^ Do not raise engine excessively. That may cause damage to engine, transmission, etc.

18. Remove cylinder head cover.





19. Remove timing chain cover bolts and nut.
20. Using lifting device, raise engine enough to allow removal of timing chain cover and remove it.

CAUTION: Do not raise engine excessively. That may cause damage to engine, transmission, etc.

After removing timing chain cover, lower engine till front torque bush and rear mounting are set onto mounting member.

CLEAN
^ Clean sealing surface on timing chain cover, crank case, cylinder block and cylinder head.
Remove oil, old sealant, and dust from sealing surface.

INSPECTION





^ Check oil seal lip for fault or other damage.
Replace as necessary.

NOTE: When installing new oil seal, drive it in until its surface is flash with edge of timing chain cover. To install oil seal, use special tool (bearing Installer).

5. Install water pump pulley.





6. Install engine RH mounting. Tighten bolts and nut to specified torque.
Tightening Torque (a): 55 Nm (5.5 kg-m, 40.0 ft. lbs.)
7. Install A/C compressor and compressor bracket.
8. Install engine front torque bush, rear mounting and rear No.2 mounting bracket.
9. Install oil pan. Refer to Oil Pan, Engine.





10. Install crankshaft pulley. To lock crankshaft pulley, use special tool (camshaft pulley holder) with it as shown in figure.
Special Tool
(A): 09917-68221

NOTE: Be sure to use the following bolts instead of pins for fixing special tool to crank pulley.

Bolt size: M8, P1.25 l = 25 mm (0.98 inch)
