Installation

1. Apply engine oil to rocker arm shaft and rocker arms.
2. Install rocker arm shaft, rocker arm (exhaust side) and rocker arm spring.





3. Check O-ring for damage or deterioration. With O-ring groove in rocker arm shaft exposed to transmission side once, install O-ring to rocker arm shaft.





4. Set rocker arm shaft so that its cut part faces down and becomes in parallel with head cover mating surface.





5. Install rocker arm shaft bolts and tighten them to specified torque.

Tightening Torque (a): 11 Nm (96 inch lbs.)





6. Fill small amount of engine oil into arm pivot holding part of rocker arm shaft. Install rocker arm (intake side) with clips to rocker arm shaft.





7. Apply engine oil to cams and journals on camshaft and put camshaft on cylinder head. Install camshaft housing to camshaft and cylinder head.
- Apply engine oil to sliding surface of each housing against camshaft journal.
- Apply sealant to mating surface of No.6 housing which will mate with cylinder head.

"A" Sealant: 99000-31110





- Embossed marks are provided on each camshaft housing, indicating position and direction for installation.
Install housings as indicated by these marks.
- As camshaft housing No. 1 retains camshaft in proper position as to thrust direction, make sure to first fit No. 1 housing to No. 1 journal of camshaft securely.





- After applying engine oil to housing bolts, tighten them temporarily first. Then tighten them by following sequence as indicated in image.
Tighten a little at a time and evenly among bolts and repeat tightening sequence three to four times before they are tightened to specified torque.

Tightening Torque (a): 11 Nm (96 inch lbs.)





8. Install camshaft oil seal. After applying engine oil to oil seal lip, press-fit camshaft oil seal till oil seal surface becomes flush with housing surface.





9. Install rocker arm shaft plug and timing belt inside cover. Then tighten rocker arm shaft plug to specified torque.

Tightening Torque (a): 33 Nm (24.0 ft. lbs.)





10. Install camshaft timing belt pulley to camshaft while fitting pin on camshaft into slot at "E" mark.





11. Using special tool, tighten pulley bolt to specified torque.

Tightening Torque (a): 60 Nm (43.5 ft. lbs.)

Special Tool, or equivalent (A): 09917-68220

12. Install belt tensioner, timing belt, outside cover, crankshaft pulley, water pump belt and engine right mounting bracket and stiffener as previously outlined.





13. After applying sealant to part "A" as shown in image, install distributor case to cylinder head and tighten its fixing bolts to specified torque.

"A" Sealant: 99000-31110

Tightening Torque (a): 11 Nm (96 inch lbs.)

Install distributor assembly.
14. Adjust valve clearance as previously outlined.
15. Install cylinder head cover.
16. Connect negative cable at battery.
17. Adjust ignition timing.
