SERVICE MANUALCONNECTING RODS, PISTONS, RINGS & SLEEVESSection 5REASSEMBLYReassemble Connecting Rods, Pistons and Rings asfollows:1.Install new connecting rod piston pin bushing using asuitable arbor press. Bore or hone the new bushingto1.6256-1.6258in.41.2902 - 41.2953 mm after assembly.2.Generously coat the piston bore and piston pin withMOLYKOTE “G-n” paste or Fel-Pro C-670.3.Insert the pin end of the connecting rod (6, Fig. 29)into the piston (7), aligning bored holes of the rodand piston (the short side of the split on the crankend of the rod is to be toward the side of the pistonmarked “CAMSIDE”).4.Align the bushing in the rod with the piston pin holesin the piston and push the piston pin (5) completelyinto position. (Pin is a loose fit at 21° C (70°F).5.Squeeze the pronged ends of the piston pin retainerrings (4) and install a ring in the groove at each endof the piston to secure the piston pin.6.Using a piston ring expander, install the rings into thegrooves of the pistons.a.The compression rings (grooves Nos., 1 and 2)must be installed as directed by the word “TOP”,“UP” or “PIP” mark stamped on the edge. Thetapered face second compression rings musthave the WITNESS MARK (shiny part) towardsthe bottom of the piston.b.The oil-regulating ring (groove No. 3.can beinstalled with either face up. The oil-regulatingring coil spring must be installed in the groovebefore the ring.7.Position the split of the TOP ring 30° from the pistonpin bore. Position the split of the second ring 180°from the top ring and position the split of the oil ring90” from the second.Figure 29. - Rod, Piston and Rings Reassembly1. Top compression ring2.
