Connecting Rod Application

Connecting Rods

Wrist pin bores on connecting rods can be finished with any of three solutions from Cogsdill: Shefcut pad-guided precision boring tool, or either of two burnishing tool designs, Bearingizing or Roll-a-Finish tool.

Crank bores on connecting rods are best finished with Shefcut pad-guided precision boring tool: radial forces are kept to a minimum, ensuring no cap-to-body separation, while producing quality bore.
