Information:
Be sure all timing pins and bolts have been removed from timing holes before turning the crankshaft.
2. Remove the nuts and cap from the connecting rod. Push the piston and connecting rod up until the piston rings are out of cylinder liner. 3. Remove the connecting rod and piston (1) from engine. Keep the caps and bearings with their respective connecting rods.Install Pistons
1. Turn the crankshaft so the bearing journal is at bottom center for piston being installed.2. Put clean engine oil on crankshaft journal, connecting rod bearings, and the piston rings. 3. Put compressor (A) on top of liner, and install the piston and connecting rod with the "V" mark on piston in alignment with "V" mark on spacer plate. Put the connecting rod in position on crankshaft while pushing piston into liner. 4. Put clean engine oil on threads of connecting rod bolts. Install the caps on connecting rods. Install and tighten nuts to 30 3 lb.ft. (4.1 0.4 mkg). Put a mark across the nuts and bolts; and turn nuts clockwise 90° from marks as shown.
Make sure the number mark on side of cap is the same number and on the same side as the number mark on side of connecting rod.
