Cylinder Head Overhaul

Cylinder Head Removal 

1. If the engine will not be removed from the traction unit, 
lower the coolant level in the engine. Loosen the hose 
clamp and remove the upper radiator hose from the 
thermostat  housing. Disconnect the coolant bypass 
hose from the thermostat housing. 

2. Remove plug from left side of cylinder block to drain 
the coolant from head and cylinder block. 

3. Remove the muffler. 

4. Remove the alternator (see Alternator Removal and 
Installation in the External Engine Component Repair 
section of this chapter). 

5. Remove the glow plug lead wires. 

6. Remove the fuel injection pipes and return pipe. 

7. Remove the rocker cover and gasket. 

8. Loosen the rocker stay attaching bolts. Remove the 
rocker assembly (Fig. 59). 

9. Loosen the cylinder head bolts. Use the sequence 
shown in Figure 60. Remove the cylinder head assem­
bly including the intake and exhaust manifolds. 

10. Remove the cylinder head gasket. Use a scraper 
tool to remove the cylinder head gasket from the cylin­
der head and cylinder block. Make sure all of the gasket 
material is removed. Do not damage or scratch the 
cylinder head or cylinder block surfaces. 

11. Remove the intake and exhaust manifolds from the 
cylinder head. Remove thermostat housing and 
thermostat.
