REMOVAL SERVICE POINTS



<<A>> CAM POSITION SENSING CYLINDER REMOVAL



Holding the hexagonal portion of the camshaft with a wrench, remove the cam position sensing cylinder.

<<B>> LASH ADJUSTER REMOVAL


caution If the lash adjuster is to be reused, be sure to clean and inspect it before installation. (Refer to.)

INSTALLATION SERVICE POINTS



>>A<< LASH ADJUSTER INSTALLATION


caution If the lash adjuster is to be reused, be sure to clean and inspect it before installation. (Refer to.)
While using care not to spill diesel fuel in the lash adjuster, install the lash adjuster on the rocker arm.

>>B<< CAMSHAFT INSTALLATION



caution
  • Do not confuse intake and exhaust camshafts.

  • A 4 mm slit is on the rear end of the intake camshaft.
Apply engine oil to the camshaft journal and cams before installation.

>>C<< FRONT BEARING CAP/BEARING CAP/REAR RIGHT BERING CAP/REAR LEFT BEARING CAP INSTALLATION



1.Place the dowel pins of the camshafts in the positions shown in the illustration.
note By getting the dowel pins into position shown in the illustration, the camshaft slots of tightening the cylinder head bolt are put in position.

2.The bearing caps No. 2 to 5 are identical in shape. Before installation, be sure to check the cap numbers and identification marks so that right bearing caps are installed in right places.
Identification marks (Die-stamped on front and No. 2 to 5 bearing caps)
    I: Intake side
    E: Exhaust side
3.Completely remove existing sealant from the bearing caps and cylinder head.

4.Apply specified sealant to the cylinder head at the points shown in the illustration.
Specified sealant:
    Three bond 1212D or equivalent
5.Install the bearing caps in position and tighten bolts increasingly by giving turns 2 to 3 times each.
note Completely wipe off excess of applied sealant that comes out.
6.Finally, tighten the bearing cap bolts to a specified torque.
Specified torque
    Front bearing cap: 25 ± 1 N·m
    Bearing cap: 11 ± 1 N·m
    Rear right bearing cap: 25 ± 1 N·m
    Rear left bearing cap: 25 ± 1 N·m
7.Check that the rocker arms are installed in position.

>>D<< CAM POSITION SENSING CYLINDER INSTALLATION



Holding the hexagonal portion of the camshaft, tighten the cam position sensing cylinder to a specified torque of 22 ± 4 N·m.

>>E<< CIRCULAR PACKING INSTALLATION



Using the special tool Circular packing installer (MD998762), install the circular packing into the cylinder head.

>>F<< OIL SEAL INSTALLATION



Using the special tool Oil seal installer (MD998713), install the oil seal into the cylinder head.

>>G<< OIL FEEDER CONTROL VALVE FILTER INSTALLATION


1.
caution Check the filter for foreign matters, damage and deformation before installation.

>>H<< OIL FEEDER CONTROL VALVE INSTALLATION


1.Apply a small amount of engine oil to the o-ring of the oil feeder control valve.
2.Install the oil feeder control valve to the cylinder head.
3.Tighten the oil feeder control valve bolt to the specified torque of 11 ± 1 N·m.
