Hydraulic Tappet Removal and Replacement
To check dry tappet clearance when reinstalling
the cylinder assembly it is necessary to remove
and bleed the
assembly. This is accomplished in the following
manner:
•
Remove the hydraulic tappet push rod
socket by inserting a finger into the concave
end of the socket and withdrawing. If the
socket cannot be removed this way, try
grasping the edge of the socket with a pair
of needle nose pliers, do not scratch the
socket.
•
To remove the hydraulic tappet plunger
assembly, form a hook in the end of a short
piece of safety wire and insert so that the
hook engages the spring of the plunger
assembly. Then gently pull the wire,
drawing the plunger assembly out of the
tappet body.
remove hydraulic plunger assemblies from
the crankcase, as this may cause the check
ball to remain off its seat, rendering the unit
inoperative.
To assemble the unit; unseat the ball by
inserting a thin clean wire through the oil inlet
hole. With the ball off its seat, insert the plunger
and twist clockwise so that the spring catches.
Remember that all oil must be removed before
the plunger is inserted.
