MAINTENANCE PROCEDURES
d. Assembly of Hydraulic Tappet Plunger Assemblies –
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. All oil must be removed before the plunger is inserted.
e. Assembly of Cylinder and Related Parts –
Rotate the crankshaft so that the connecting rod of the
cylinder being assembled is at top center of compression stroke. This can be checked by placing two
fingers on the intake and exhaust tappet bodies. Rock crankshaft back and forth over top center. If the
tappet bodies do not move the crankshaft is on the compression stroke.
(1) Place each plunger assembly in its respective tappet body and assemble the socket on top of
plunger assembly.
(2) Assemble piston with rings so that the number stamped on the piston pin boss is toward the front
of the engine. The piston pin should be of a hand push fit. If difficulty is experienced in inserting
the piston, it is probably caused by carbon or burrs in the piston pin hole. During assembly,
always use a generous amount of oil, both in the piston pin hole and on the piston pin.
(3) Assemble one piston pin plug at each end of the piston pin and place a new rubber oil seal ring
around the cylinder skirt. Coat piston and rings and the inside of the cylinder generously with oil.
