4a. REMOVAL
1) Remove the manifolds as detailed earlier.
2) Remove the valve rocker arm shaft assembly as
detailed earlier in para 3a.
3) Remove the push rods and identify them so they
can be installed in their original positions.
4) Remove the thermostat housing by pass hose.
5) Remove the three bolts then remove the
thermostat housing.
6) Remove the fuel injector pipes. It is not advisable

NOTE:
1. Clean the Engine externally. Mark dismantled
parts such as valves, Valve stem guides and
springs and place them on a table in removal
order to facilitate reassembly.
2. Always cap all exposed openings of injector
pump, injector pipes, fuel lines and nozzle
holders to prevent entry of dirt into the fuel
system.
3. To avoid warpage do not remove cylinder head
bolts unless the engine has cooled down.
