Why It Matters
A spun rod bearing, a stretched big end or a seized wrist pin usually means the rod is scrap. Rebuilders also find rods that are out of round, bent, or have worn small-end bushings that knock at idle. On a stock rebuild it is important that all four rods are the same weight, or the engine vibrates. Being able to buy a single rod lets you replace one damaged rod, as long as you balance it to the others.
Installation Notes
- Have a machine shop check the rod for straightness and big-end roundness, and fit the wrist pin to the bushing.
- Weigh all four rods and balance end-to-end before assembly.
- Use new rod bearings sized to your crankshaft, clean everything, and pre-lube with assembly lube.
- Install with the forge marks (casting bumps) facing up as described in your workshop manual, and torque the rod nuts to the factory figure.
- Check side clearance and that the crank turns freely after each rod.
