Cylinder Head: Installation

NOTE:

Thoroughly clean all parts to be assembled.
Always use new cylinder head and manifold gaskets.
Always use new cylinder head bolts.
The cylinder head gasket is a metal gasket. Take care not to bend it.
Rotate the crankshaft to set the No. 1 piston at TDC (Top Dead Center).
Remove the oil, dust on the cylinder head and cylinder block surfaces where gasket is seated to prevent scratches.

Install the cylinder head.

Remove the hardening sealant, oil, cleaning residue, foreign materials remaining on the cylinder block and cylinder head.

Apply liquid gasket on the top of the cylinder block.

Bead width: 2.0 - 3.0 mm (0.07 - 0.11 in.)

Sealant: MS 721-40 AA or AA0

NOTE:

Be careful not to change the mounting direction of the gasket.
Comply with the amount and application position of the sealant so that the liquid gasket is penetrated and applied to the gap between the cylinder head gasket layers.
Assemble the cylinder head and its mounting bolts before the liquid gasket begins to harden. (Within 5 minutes)
Do not run the engine for 30 minutes after assembling the cylinder head bolts.

Apply liquid sealant on the top of the cylinder head gasket.

Bead width: 2.0 - 3.0 mm (0.07 - 0.11 in.)

Sealant: MS 721-40 AA or AA0

Install new cylinder head bolts.
1. Do not apply engine oil to the new cylinder head bolts.
2. Tighten the cylinder head bolts in several passes.
  Tightening torque: 1st step: 56.9 - 60.8 N.m (5.8 - 6.2 kgf.m, 42.0 - 44.8 lb-ft)
  
  2nd step: 100 ~ 104°
  
  3rd step: 100 ~ 104°

  NOTE:
  - Do not reuse the cylinder head bolts.
  - Do not apply engine oil to the cylinder head bolts.
  - Remove the extruded sealant of the cylinder head and block within 5 minutes after assembling cylinder head bolts.
Install the hydraulic lash adjuster (HLA) (A) and the swing arm (B).

Place the cam carrier on the cylinder head.

Remove the hardening sealant, oil, cleaning residue, foreign materials gathered in the bottom of the cam carrier and on the top of the cylinder head.

Apply a continuous bead of liquid gasket to the bottom surface of the cam carrier, as shown in the figure below.

Bead width: 2.5 - 3.5 mm (0.09 - 0.13 in.)

Sealant: MS 721-40 AA or AA0

The dowel pins on the cam carrier and holes on the top of the cylinder head should be used as a reference in order to assemble the cam carrier in exact position.

Install the cam carrier (A).

Tightening torque: 18.6 - 22.5 N.m (1.9 - 2.3 kgf.m, 13.7 - 16.6 lb-ft)

NOTE:

Assemble the cam carrier within 5 minutes after applying sealant.
Assemble the camshaft bearing cap within 5 minutes after assembling the cam carrier.
(Refer to Cylinder Head Assembly - "CVVT & CAMSHAFT ")
The engine running or pressure test should not be performed within 30 minutes after assembling the cam carrier.
