Default Naphtha

When using naphtha to clean diffs is it ok to put the diff case(plastic) in it?

Naphtha is a breeze. Open up the diff, remove bearings and o-rings, put in naphtha for 1-2 minutes. Pull out and wipe dry and they look clean as new.

VM&P the most common Naphtha contains Benzene and can cause skin cancer and nerve damage, "Hardly" is still to much contact
I have a freind that is still going through the side affects of over exposure, his name is Dave Richer

This seems like a really unnecessary step in the maintenance process. Just dump it all on a towel. Wipe out the inside of the case with a paper towel. Let the oil run off the gears onto the towel. Reassemble and refill. Takes like 60 seconds if you do it often enough.

Easiest way to clean diff internals is with an ultrasonic cleaner... just let the excessive oil drip off the parts then add them to the ultrasonic cleaner. Benefit is you don't need to use super harsh chemicals, as mineral oil is displaced relatively easily with the right solvents.

Those of you using Naptha make sure your get all the Naptha off your gears and or diff case because it will break down your oils if you don't clean it off. I use it only on metal gears and then I blast off the Naptha with break cleaner and forced air before I RE-assemble. Leaving any trace on parts will quickly turn your 5000 diff oil into 3000.

It does not evaporate completely once it mixes with silicone oil. In a pure state yes it evaporates but once it becomes contaminated it clings to your gears and diff case. Just be sure to wipe it all off good, or blast it with air or whatever you prefer because it will break down the new oils if more than a trace is left. If you look good at the grooves in the gears you will see the residue and since its such a PITA to wipe between the teeth I just blast them all off with break cleaner.
