Compressor oil change ~ old Sears 106.153991 air compressor
I have 20+ yrs old sears 2hp mo.# 106.153991.
Would like to know how much oil it takes?
Howdy:
Difficult to say without actually seeing the unit and I can’t find a picture of it anywhere.
At the base of the compressor head you should find a drain for the compressor oil, and often just above that will be a sight glass to help you determine whether your unit has enough oil.
Just below the sight glass is the oil drain for my compressor.
Near the top of the compressor head will be a vented fill port which you unscrew to allow you to pour compressor oil in.
All I do when it’s time to change my oil is drain the crankcase through the drain port, replace the drain plug, and then slowly add oil through the fill port while I’m watching the sight glass to make sure I don’t overfill.
My guess is that you’re dealing with a few ounces of compressor oil to fill yours.
Hope this helps.
Please provide a photo of your compressor, and a close up of the oil fill tube and sump if the compressor has one. We’ll take another look if you are still having problems with it.
I would like to know where to drain the oil and then refill on a sears air compressor model 6340. Photo attached. Thanks, Bob
Visualize lines from the diagonals of your pic. Just below where the lines intersect are two squarish plugs in an “L” configuration. Those are the drain (horizontal) and the fill, (vertical).
I’d check the level at the fill plug first. It’s probably close to the bottom of the threads, and that would the correct level, most likely.
Then drain the oil and refill to where it was, or close to the bottom of the threads. Do not fill above the fill hole threads.
BTW, that’s either a 919.176730 or 919.176830. MO-6340 is the motor ID.
Bob,
Here is a link for a manual that fits your “type” of compressor. In it you will find where and how & what type oil, to change your compressor’s oil.
Your link was removed from this post as well as the manual is already available on this site here: https://about-air-compressors.com/craftsman-air-compressors/
I am changing the oil in my Sears 919.176054 compressor and I need to know how much oil and where to pour it in.
Also a manual would be appreciated
I am sending 3 pictures of the compressor.
There’s a parts drawing at sears, and any manual for a direct drive compressor will tell not much less than a manual for this, which is 919.176051, by the way. In your first pic, at the bottom of the pump near the motor there are two square head plugs. You drain from the bottom one and fill from the top one. You’ll probably have oil near the bottom of the threads in the fill hole presently – that’ where the fresh oil level should be. Can’t tell exactly how that will take, but probably not more than a quart, so… Read more »

Hi Johnny. Thanks, but your link was removed as the manual is already available on this site here: https://about-air-compressors.com/craftsman-air-compressors/
