I have a Sears Craftsman/Husqvarna 16" electric chain saw. The plastic gea r that is driven on its inside diameter by the gear on the end of the motor shaft finally wore out and I have a new plastic gear from Sears. But, no info on what type of grease, if any to put on the plastic gear and "pinion" gear that Sears calls the gear on the end of the motor shaft that drives t he inside diameter of the plastic gear.
Suggestions - polite ones only please .
