6.7L Cummins Cam Followers/Tappets – Tappet – Remove

Use tappet removal tool kit, Part Number 3822513, to remove the tappets.
Push a wooden dowel rod into each tappet. It will probably be necessary to push the dowel into the tappet with a soft-
face hammer.
NOTE: When properly installed, the dowels can be used to pull the tappets up and will require considerable effort
to be pulled out.

Pull each valve tappet up until it makes contact with the cylinder block. Put a rubber band around two dowels. This
will hold the tappets up off the camshaft.

Remove the camshaft. Refer to Procedure 001-008 in Section 1.

Insert the trough from the tappet replacement kit, Part Number 3822513, to the full length of the camshaft bore.
NOTE: Make sure the trough is positioned so it will catch the tappet when the wooden dowel is removed.

Only remove one tappet at a time.
Mark the position of the tappets as they are removed. The tappets must be installed in the same position when the
engine is assembled.
Remove the rubber band from the two companion tappets.
Secure the tappet that is not to be removed with the rubber band.

NOTE: When the tappet is dropped into the trough, most of the time it will fall over. However, if it does not, gently
shake the trough just enough to allow the tappet to fall over before removing.
Pull the wooden dowel from the tappet bore, allowing the tappet to fall into the trough.

Take special care not to knock or shake the tappets over the end of the trough.

Carefully pull the trough and tappet from the camshaft bore, and remove the tappet. Repeat the process until all
tappets are removed.
