Process worked as expected.
This is the second drive sprocket that I have replaced on this chainsaw. The saw gets a lot of use and I am happy with getting parts from eReplacementParts.

Difficulty

Time

Tools Used
Screwdriver, Pliers, Socket set
Parts Used
Remove chain guard and chain and bar itself. Remove the sparkplug and make sure the piston is at bottom of cylinder. push a line of 1/4 to 3/8 rope into the cylinder until it won't go no more, leaving enough out so removing it will be easy. turn the engine clockwise until the piston is tight against the rope. Use a flat punch and small hammer to tap the worn out sprocket so it turns clockwise. The thread if opposite of a common bolt thread. The sprocket should quickly come loose and spin off. remove the old needle bearing and grease the new one and place it on the shaft, spin the new sprocket onto the engine shaft and tap it in place. Turn the engine enough to loosen the rope and remove the rope. Replace the spark plug and assemble the bar, chain and chain guard. Tighten chain properly, add fuel and chain oil and start the saw up, it should work great.
