Inlet Valve Adjustment - Volvo EPA2007 D13F Reference Manual

Inlet Valve Adjustment

WARNING
Apply the parking brake before barring the engine over. Remove the EMS power
supply fuse to avoid starting the engine unintentionally. Make sure that the
transmission is not in gear.
With the engine cold, 60°C (140°F) or less, check and adjust the valves and injector
as required for each cylinder before moving to the next. Follow this sequence of
cylinders when adjusting clearances: 5, 3, 6, 2, 4 and 1.
1. Using the flywheel turning tool, 88800014, bar the engine over manually to the
appropriate camshaft marking for adjustment of the inlet valves and injector for that
cylinder.
2. Using a feeler gauge, check the clearance between the rocker arm adjusting screw
and the valve yoke (bridge) of the inlet valves.
3. If the clearance is not within specification, loosen the locknut and adjust the
clearance as required.
4. Hold the adjusting screw to prevent it from turning and tighten the locknut to
specification.
5. Recheck the clearance after tightening the locknut.
6. Mark the respective rocker arm as each adjustment is completed.
