Obtain the correct new cylinder head bolts

Obtain the correct replacement head gasket

All items are clean and free from damage and corrosion

Location dowels are correctly installed into the crankcase

New head gasket is positioned correctly on the crankcase mating face

Cylinder head is correctly located on the dowels

New cylinder head bolts are installed

Obtained the correct service parts

Fuel pipes from the injectors disconnected and removed

Check the main bearing surfaces for damage and excessive wear

Measure the crankshaft diameters to confirm they are within service limits, refer to Technical Data (PIL 15-12)

Check that the oil-way cross drillings in the crankshaft are clear and free from debris. Blocked or restricted oil-ways will cause oil starvation at the big end bearings

Check that the piston cooling J-jets are clear. If the J-jets cannot be cleared remove the fixing screws. Remove the J-jets and discard them

1. Clean off all traces of the old sealant compound from the crankcase and bedplate mating faces.

2. Use a suitable degreasing agent to carefully clean the main bearing saddles in the bedplate and crankcase. Take care not to block the oil ways or the piston cooling jets.

Consumable: Cleaner/Degreaser - General purpose solvent based parts cleaner

Important: Anaerobic sealant will not start to cure whilst it is open to the atmosphere, however when air is excluded (for instance when the two parts are put together) it will immediately start to harden. Make sure that all the necessary tools, bolts etc. are readily available prior to assembling the components. The parts must be installed and tightened to the correct torque value within 5 minutes (with a maximum permissible time of 15 minutes).

Important: BEFORE installing the bedplate: DO NOT rotate the crankshaft. Make sure that the upper main bearing shells are flush with the bottom face of the crankcase.

1. The installation procedure is the opposite of the removal procedure. Additionally do the following steps.

2. Make sure that all items are clean and free from damage and corrosion.
