What weight of oil is in a Sawzall?

My old but not-so used Sawzall has started to run very hot in the gearbox. (The motor smells fine and is not hot). I thought that maybe oil had slowly been lost over the years or it had deteriorated. When I removed the gearbox (front) end from the motor (back end) I saw oil as thick as ketchup. It hardly flows at all. Is this normal? Does anyone know what weight oil I might replace it with? Thanks!

That's grease, not oil.
The only saws that have an oil resevoir are the worm drive circ saws.
Find out what Milwaukee recommends. I believe there are quite a few different lubricants used in their tools.

It is a specific type of grease in the sawzall. I had to repair mine and the local Milwaukee service center told me what type of grease it was (I can't remember) and of course, I went to the local auto parts store to see if I could get some. No luck. I went back to Milwaukee and bought some from them. They were actually really nice about it, and gave me the approxamte amount I needed in a zip-loc bag.
When I got home, I cut the corner off the bag and squeezed it in like toothpaste.
Good luck, and have the serial # handy when you call your local shop.
I meditate, I burn candles, I drink green tea, and still I want to smack someone.
probably white lithium grease. The old being black means that either it is full of metal filin worn off or dirt, or that there some Moly in the original grease.

Milwaukee sells various greases for their tools. The type of grease is noted in the manual for the tool.
I would have thought that it would be consistent for sawzalls, but the manual for mine (which is about 30 years old) states that 'Type B Grease' should be used. A manual for a different model that I viewed online said that 'Type A' was called for.
I've tried bearing grease and whatever was in my grease gun at the time, and neither seemed to do the trick (i.e., the sawzall still was noisy and hot). I've had good luck using the Milwaukee grease, though.
Here is a very handy document from Milwaukee that shows the correct grease for each tool. It is dated July 2002. Let us know if you find a more recent version
