Start By:
- Remove the valve mechanism cover, the electronic unit injector, the rocker shaft and the push rods.
NOTICE |
---|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: The following procedure is for the removal of the inlet valve springs and the exhaust valve springs without removing the cylinder head. This procedure can be performed on only one cylinder at a time. This will prevent the inlet valves and the exhaust valves from falling into the cylinder.
- Rotate the crankshaft in order to bring the piston to the top dead center position in the cylinder.
- Place the bottom portion of Tool (A) on the cylinder head. Install the hold down bolt (1) .
