(Fig. 78).
(4) Raise dowel rod (disengage from tappet) and
allow tappet to fall into trough (Fig. 79).
(5) Carefully remove trough (do not rotate) and
tappet. If the tappet is not being replaced, mark it so
it can be installed in its original location.
(6) Re-install trough and repeat procedure on
remaining tappets.
