Repair Instructions
9 Repair instructions
9.1 Motor case assembly
Install the pin (DP114) into the motor case until approximately 1/8” is exposed in the distributing valve
bushing hole.
Install the valve bushing (MA311) into the motor case counterbore until it is flush with the inside edge of
the counterbore. The valve bushing has a slot to enable proper alignment during assembly.
The valve bushing must be placed in a freezer, for a period of time, before assembling into the
motor case. This will cause the bushing to contract allowing easier assembly into the motor
case.
9.2 Piston assembly
Install the five (5) cylinder liners in the cylinder holes of the motor case until they bottom out. •
Lightly oil all pistons and cylinder liners. •
Insert the master piston assembly directly across from the breather cap hole and to the rod retainer •
assembly.
Assemble the piston pin (MA325) with the threaded side up.
•
Place the connecting rod washer (MA326WA) over the connecting rod (washer ears go to the side •
of the connecting rod).
Tighten the connecting rod nut (MA326N) and bend the washer ears over the nut.
•
Assemble the other four (4) pistons to the rod retainer assembly using the piston pins (MA325). •
After all piston pins have been installed, secure with the retaining ring (65W1). •
Position the gaskets and cylinder caps over the cylinder holes and secure using the 75V10 screws. •
Tighten all screws to 7 ft. lbs. (9.5 Nm) torque.
