Locked up air tools
 

I just recently got a compressor going again, and now most of my air tools are locked up, I'm guessing from sitting for years without use. I have oiled them, no workee, what else can I do? Would soaking them in a penetrating oil help? Are they hard to repair, or do I need to just get new ones? Most are C/P kind of quality, a few off brands I picked up here and there or got in trades.

I'm putting over 100# of air to them and they don't even budge.

They are probably rusted inside. I would take them apart and see if you can get them to move.

Fill them with Marvel Mystery Oil and walk away from them for a day, then give them a try.
If that doesn't free them, just open them up & clean everything real good. My personal preference is WD-40 & 0000 steel wool. Make sure you get any tiny particles out, reassemble, then put them back to work.

Listen to El Jay. Marvel Mystery oil is good stuff. Make sure and trigger the tool while pouring it in the tool so some of it gets where it needs to be. It don't hurt to tap them lightly with a hammer to cause a jarring motion in the tool. If all that fails then you know what comes next. Good luck.

I forgot to add, if it comes to tearing it open & you're worried about it; ask yourself this question, "What's the matter, you afraid you're going to break it?"

Thanks guys, I just put about 3 pints of MMO in a dozen or so tools, found out about triggering them on my own, LOL! This time tomorrow should tell the tale, besides I need to get all matching fittings for them, I hate having to change fittings just so I can use a different tool.

I completely agree with the MMO. HOWEVER! DO NOT hold the tool anywhere near your face when you power it. All that oil will blow out as the tool starts to turn.


MMO tastes nasty if you must know. :uhmk:
