Method Two: Adjust All Valves Using Two Crankshaft Positions
Method Two: Adjust All Valves Using Two Crankshaft
Positions - EuroV MBE900
Method two allows you to adjust all the valves using just two crankshaft positions.
- Using the cranking device, turn the crankshaft until cylinder #1 is at the ignition TDC position (all valves are closed) and cylinder #6 (cylinder #4 on the four-cylinder engine) is at the valve overlap position (all valves are open).
- Check the valves listed in Table "Valve Adjustment - Method Two" in the "Ignition TDC" row and adjust them (if necessary), using the procedures under the headings "Checking Valve Lash" and "Adjusting Valve Lash."
- Using the cranking device, turn the crankshaft until cylinder #6 (cylinder #4 on the four-cylinder engine) is at the ignition TDC position (all valves are closed) and cylinder #1 is at the valve overlap position (valves are open).
- Using the same procedure, check the valves in the "Valve
Overlap" row and adjust them (if necessary), using the procedures
under the headings "Checking Valve Lash" and "Adjusting Valve Lash."
