Connecting Rod Bearing: Description and Operation

DESCRIPTION

Connecting rods are forged in one piece from steel, and cracked rather than machined along the split line, providing a perfect fit for the two halves and reducing weight by 20 percent compared to a fully machined rod and cap while also greatly reducing machining. The rods are drilled longitudinally to deliver oil under pressure to the wrist pins, minimizing wear for long life. Thirty-degree offset crank pins on the crankshaft provide even, 120-degree, firing intervals for smooth operation. The crankshaft with these split pins has ample strength without adding material between the pins, keeping the engine compact and reducing weight.
