Expert Guidance from Bryton

In this episode, Bryton, machinist at Industrial Injection, takes the helm to guide Scott through the complex process of reconditioning 12 valve connecting rods. The task is meticulous: they start by honing the crankshaft surfaces of the rods to ensure smooth and precise functionality. Next, they replace the wrist pin bearings on the opposite side of the rods. These components are crucial for the smooth pivoting of the rod and piston assembly.

But the work doesn't stop there. Bryton and Scott balance the rods meticulously, an essential step to guarantee that the engine runs smoothly and efficiently. Balancing is critical; even minor imbalances can lead to significant engine issues down the line.
