ASSEMBLY
NOTE: The piston, connecting rod and related parts are shown above. Check the fit of a new piston in the cylinder bore before assembling the piston and piston pin to the connecting rod.
1. Apply a light coat of recommended quality engine oil SF to all parts. Assemble the piston to the connecting rod with the indentation in the piston positioned as shown above.
2. On replacement connecting rods, install the large-chamfered side of the connecting rod bearing bore toward the crankshaft cheek; facing toward front of engine on the RH bank rods, and facing toward rear of engine on LH bank rods.
3. Start the piston pin in the piston and connecting rod (this may require a very light tap with a mallet). Using an arbor press and Piston Pin Remover/ Replacer T68P-6135-A or equivalent, press the piston pin through the piston and connecting rod until the pin is centered in the piston.
