6. Turn the engine over until the camshaft lobes for the
valves to be adjusted point directly away from the
valves.
Cam Lobe Pointing Away From Valve
7. As the valves begin to close, the tool legs will
prevent the valves from rising, allowing the shims to
be removed using a soft faced lever and a magnet.
NOTE:
• The shim is often a tight fit in the tappet. Use a
suitable soft faced lever and a magnet to
remove the shim from the tappet.
Removing/Replacing The Shim
8. Select a new shim using the charts shown
overpage.
9. Take the selected replacement shim and lubricate
with engine oil. Fit the shim to the top of the tappet
by reversing the removal procedure.
10. Turn the engine over until the camshaft fully opens
the valves being adjusted. Remove the tool when
the valve is fully open. Check that the shim has
seated correctly and adjust, if necessary, before
proceeding.
NOTE:
• The tool is designed to allow adjustment of 2
pairs of valves without moving the mounting
plate. This is achieved by moving the tool legs
to a new location once one pair has been
adjusted.
11. Repeat the procedure until all valves have been
adjusted.
NOTE:
• A shim selection chart can be found on the
following two pages.
