Keeping your chain saw’s bar, chain and drive sprocket in tip-top shape involves more than regular chain sharpening and re-tensioning. Even with meticulous care, a chain saw’s drive sprocket and bar eventually wear out and must be replaced. We asked our small-engine expert, Roger Wyatt at Reed’s Sales & Service, to walk us through a typical chain saw “front-end job.” He showed us how to keep a saw on the cutting edge. You can replace all the drive components yourself in about an hour.
