TM 10-3950-672-24-2
If difficulty is experienced in getting the tappet to make
the bend from the trough up to the tappet bore (due to
the webbing of the block), pull the trough out enough to
allow the tappet to drop down and align itself, then pull
the tappet up into the bore.
After the tappet has been pulled up into position, slide
the trough back into the cam bore and rotate it 1/2 turn.
This will position the round side of the trough up, which
will hold the tappet in place.
Remove the installation tool from the tappet.
Install a wooden dowel into the top of the tappet. Wrap
rubber bands around the wooden dowels to secure the
tappets.
Repeat this process until all tappets have been installed.
Camshaft Installation
Apply a coat of Lubriplate 105 to the camshaft bores.
