ISM, ISMe, and QSM11 – 002-004   Cylinder Head

Table of Contents




A plastic insert is installed in all fuel inlet passages on new and ReCon® cylinder heads.

The fuel inlet passages are the lower row of drillings.


Depending on the fuel plumbing option, one fuel inlet passage insert must be removed to allow fuel to flow to the injectors. If the insert is not removed, the engine will not start.

Remove the pipe plug and use a sharp object to pull the insert from the hole.


Install the cylinder head lifting bracket, Part Number 3822476, with two rocker lever support mounting capscrews and two long rocker housing mounting capscrews.

Tighten the capscrews.

Torque Value:  47  n.m  [35 ft-lb]



This component or assembly weighs greater than 23 kg [50 lb]. To prevent serious personal injury, be sure to have assistance or use appropriate lifting equipment to lift this component or assembly.

Do not drop the cylinder head on the cylinder head gasket. The gasket material can be damaged.

Install the cylinder head gasket.

Use a hoist or hydraulic arm and install the cylinder head.

Use clean 15W-40 oil to lightly coat the cylinder head capscrew threads and bottom of the flange.

Allow the excess oil to drain from the capscrew threads.


Remove cylinder head lifting bracket, Part Number 3822479.


Install the seven hex flange head capscrews with new sealing washers on the fuel pump side of the engine.


Install the remaining 32 cylinder head capscrews in the sequence shown.

Be sure to install the three short capscrews inside the intake ports.


All of the 32 capscrews, old and new, must be rotated 180 degrees after they have been tightened according to torque step 2. Make a mark on the cylinder head as a reference. Rotate the capscrew more than two flats and but less than three flats.

After tightening according to torque step 2, mark the cylinder head as a reference.

When using torque plus angle, the tolerance on the 180-degree angle of rotation is between two and three flats. If the capscrew is unintentionally rotated beyond three flats, do not loosen the capscrew. The clamp load is still acceptable. However, rotating the capscrew beyond three flats reduces the number of potential reuses.

NOTE: This torque procedure is applicable to both old and new capscrews.


Tighten all the capscrews in the sequence shown to the specified values:

Torque Value:

  1. 68 n.m   
    [50 ft-lb]
  2. 136 n.m   
    [100 ft-lb]
  3. Rotate 180 degrees.

NOTE: Rotate at least two flats, but not more than three flats.


Tighten the seven capscrews in the fuel pump side of the cylinder head in the sequence shown.

Torque Value:  68  n.m  [50 ft-lb]
