Tappet Changing Tool, Part No. 3822513
Insert the wooden dowels through the push tube holes and
into the top of each tappet securely. When properly in-
stalled, the dowels can be used to pull the tappets up and
should not be able to be pulled out without considerable
effort.
Pull the tappets up, and wrap a rubber band around the top
of the dowel rods. This will prevent the tappets from drop-
ping down.
