Required Tools

Tool Part Number Part Description Qty

A 9U7257 Cradle 1

B 9U7256 Guide 1

C 9U7225 Camshaft Pilot 2

D 9U7240 Camshaft Hook 2

H 9U7243 Alignment Sleeve 1

J 8T2998 Lubricant

K 9S3263 Thread Lock Compound

NOTICEKeep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.

NOTICEDo not turn the crankshaft or the camshaft while the camshaft gear isremoved. If the front gear group is not correctly timed during



installation, interference can occur between the pistons and the valves,resulting in damage to the engine.

NOTICECare must be used when removing or installing the camshaft. Do notdamage the finshed surfaces of the camshaft or the camshaft bearings.

1. Ensure that the camshaft and camshaft bearings are thoroughly clean. Lubricate the camshaftlobes with a 50/50 mixture of Tooling (J) and clean engine oil. Apply a thin coat of cleanengine oil on the camshaft bearings.

2. Install Tooling (A) on the cylinder head at Location (Y) .




3. Install Tooling (B) on front housing (7). Do not tighten the bolts that hold Tooling (B) to fronthousing (7) at this time.

4. Use Tooling (H) to align Tooling (B) with the camshaft bearings. Tighten the bolts that holdTooling (B) to front housing (7). Remove Tooling (H) .

Note: Tooling (H) should move freely from the bore of Tooling (B) .


5. Install Tooling (C) on the rear of the camshaft.

6. Use two technicians to install the camshaft. Use Tooling (D) to assist in aligning camshaft (8)with the camshaft bearings. Carefully slide the camshaft into the cylinder head from the front of



the engine. Keep the camshaft level while the camshaft is being installed in the cylinder head.The weight of the camshaft is approximately 39 kg (86 lb).

Note: Rotate the camshaft during installation. This will prevent the camshaft from binding inthe camshaft bearings.

7. Remove Tooling (C) and finish installing camshaft (8) in the bore.

Note: Tooling (C) must be removed before the camshaft can be completely installed in thecylinder head.

8. Remove Tooling (A) from the cylinder head.

9. Remove Tooling (B) from the front housing.


10. Install the Oring seal on cover (10). Position the cover on the rear of the cylinder head. Installflat head screws (9) and tighten to a torque of 13 ± 3 N·m (10 ± 2 lb ft).




11. Install Oring seals (5) and (6) in sealing plate (3). Lubricate Oring seal (6) with a 50/50mixture of Tooling (J) and clean engine oil.





12. Install sealing plate (3) in front housing (7). Install adapter assembly (4) in the sealing plate.Ensure that the dowel in adapter assembly (4) engages the hole in the camshaft.

13. Install thrust plate (1) . Apply Tooling (K) to bolts (2). Hold the thrust plate in position andinstall bolts (2). Evenly tighten bolts (2) until sealing plate (3) and the Oring seal are seatedagainst the cylinder head.

Note: Ensure that the Oring seal stays in the groove in sealing plate (3) .

End By:

a. Install the rocker arms and the rocker shafts. Refer to Disassembly and Assembly, "RockerArms and Shaft Install".

b. Install the camshaft gear. Refer to Disassembly and Assembly, "Camshaft Gear Remove andInstall".
