FIGURE 27. CONNECTING ROD.
Connecting rods that are used with fixed or full-floating pins generally have a bushing-type bearing pressed into
the pin hole. The lower end is fitted with two-piece bearings that encircle machined bearing surfaces of the
crankshaft throws. Connecting rod bearings with too much running clearance will cause a knocking noise and
can result in a broken rod or a scarred crankshaft throw.
