Air ratchet repair.

[dodge man]

I have a Chicago Pneumatics that is probably about 30 years old. Today it stopped working when it is under a load. It sounds like it’s working but won’t turn. This is the case tightening or loosening. If it’s not under load it spins fine. Can these be fixed or rebuilt.

should be just a phone call away for your answer. If not rebuilt a new head should be available.

If the tool has been properly lubed and had decently clean air throughout its life three o-rings will usually put it back to as new condition. Sometimes the rotor blades need to be replaced.

I fix a lot of stuff. I fix it if I dont have to buy anything or can buy something generic or stock to fix it. All those parts are expensive and hard to get and the thing is 3/4 worn out already. 3/8 ratchets something I never had much luck with and they dont last as long anyway which might not be such a deal.
Parts for the savvy may not be a problem, maybe its a hobby but with discount vendors a guy can score a new one in a box, new model for 30 or 40more than putting a part in to a worn out one. They call that,,,, all parts available,,,,, new in box,, all assembled.

I ran a bunch of PB Blaster through it than air tool oil. When I looked it over before hand it looked like it might have been gunked up. Maybe it’s fixed now??

If it works you are a winner for cheap.

Most of the time I find that the rotor blades get gunk on them from the oil residue and they no longer slide out and seal. This allows air to pass around them. If it's working after putting oil in it chances are you got them unstuck. I would still take it apart and clean up the internal parts. Chances are it'll last for decades more.

It’s been a while since I had used it to.

Easily 3/4 of the problems I've had with pneumatic tools is a sticky blade. Either a good clean/lube or jewelers rouge has fixed them all.

You simply need a head repair kit.
The ratchet pawl and springs are worn out.
I sold and rebuilt hundreds during my many years with Mac Tools.
Probably can buy them online by now.
Most are generic.
Don't know your model,but the CP828 with the gold knob was different.
Flip over,remove snap ring,shift into "neutral,slide out head kit,clean and lube,reinstall.
Really worn units will need a yoke as well.
Classic symptoms-runs but no power.
Good Luck!

I repaired/rebuilt, a lot of them many years ago, sometimes when the mechanic/owner had already tried to do it himself. It's like anything else; not a bad job IF you know what you're doing and almost impossible otherwise. I usually started by disassembling tools and thoroughly cleaning them in my parts washer.

 

[dodge man]

Yes it’s a CP 828, I found the paper work. I’m not suse what shifting to neutral is. Just hold it between neutral and reverse? I took the snap ring off but couldn’t get it apart. I saw it was gunked up under the snap ring and that is when I ran some PB Blaster through it.

I found the paperwork with an exploded view but directions on how to take it apart. Might be time for a You
Tube video.

I have the same vintage ratchet.... Like others have stated, run some on blaster threw him, Reverse and forward. I do the same now and again prolly once a Year or so with my impact guns and ratchet.

Old mechanic friend of mine would run solvent or mineral spirits threw his air guns and ratchets followed by air tool oil when air tools had ailments.

 

[WranglerX]

Some times people forget air tools need lube occasionally.... Try the PB blaster thing then follow up with pneumatic tool oil...

Or similar product...

You are correct about shifting into neutral.
Wiggle the knob a little while you try to remove the head kit.
It will come out.
No amount of lube will overcome the worn parts.
Search CP828 head kits.
Techs used to keep the head soaking overnight in ATF to help with service life.
Body shop guys would use plastic head boots to keep out the dust.
Good Luck!
