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 <g>.
When in doubt , use white lithium grease . What color was the remnant of
grease that was in there ? That should give you a clue , if black it was
probably a moly-type , white/gray probably lithium . There are also other
colors , they're usually intended for a specific purpose though .

lithium grease seems reasonable.
There is probably a "correct" grease. I'd expect
any kind of automotive wheel bearing grease would
do a reasonable job.
The cleaning out might be the more important step.
If it were my saw, I'd start with cotton swabs, and
get what I could. And then take it outdoors and blast
it out with aerosol brake cleaner solvent from the
same auto parts. Plenty of time to dry.
Yeah, cleaning out the old krap so it doesn't start wearing out the new parts is very important, I'm planning on swishing some gasoline on the parts to get them clean, allowing them to dry, and then using some grease from my grease gun to start out fresh.

Did you look at the parts list on Sears Parts Direct website? There
might be grease listed as a not-illustrated part.
I wonder if any grease might be a problem? Debris would tend to stick
to it, accelerating the wear-out of the plastic gear. Plastic against
metal may not need lubrication in some applications.
