TAPPET REMOVAL
Remove Camshaft as outlined in Camshaft/Service and Repair.
Insert the trough to the full length of the cam bore.
Make sure the trough is positioned so it will catch the tappet when the wooden dowel is removed.
NOTE: Identify the location of each tappet as it is removed. The tappets must be installed in their original locations.
Only remove one tappet at a time. Remove the rubber band from the two companion tappets, securing the tappet not to be removed with the rubber
band.
