This set includes all of the gears you'll need to replace your plastic gears including the two-speed gearset inside the headstock.Fit and finish isn't fantastic. The bore is slightly undersized so you'll have to lightly hone it to git your shafts. The teeth are sharp and have burrs. I cleaned them up with a wire wheel on my bench grinder and that really helped.This kit includes the timing belt gears and timing belt which fits the two-speed lathes. The belt lengths and drive gear are different on the two-speed lathes and those parts won't work if you have a single speed. The motor-side timing belt pulley is not keyed nor does it have a set screw. You'll need to find a way to secure it to your motor shaft. I drilled and tapped a set screw.You should note that these are noisy. Much more so than the plastic gears. I've included a video showing them running on my lathe. I would definitely buy these again regardless of fit and finish.
