Ratchet runs without pushing trigger, what would be the common cause?

David for model number CP 828 asked on 2022-10-02

Hello David, Thank you for your inquiry. Check the throttle bushing, the valve stem, and the throttle spring, as if any of these parts are damaged or stuck, it can cause the ratchet to run all the time. Remove the roll pin from the lever as well and check for any debris that could keep it from closing off the air. Check the air intake as well for any debris and put a few drops of machine oil in it to loosen it. Good luck with your repair.

Question: Bearing Lubrication During Re-as...

1560073

When re-assembling the air ratchet, do you grease the bearings or does the air tool oil take care of the lubrication? If grease is to be used, what is the best grease to use?

Hello 1560073,

You can lube the Ball Bearings with just a little bit of gear lube. You will not want to have the gear lube spreading throughout the internal parts of the Chicago Pneumatic CP828 (T022708) 3/8" Ratchet. And yes the oil will help to keep them lubricated.

Question: Cp828 Air Ratchet

turne99

Hello turne99,

The thing to do is probably breakdown the the tool and look for parts that might show some wear on them. Look at the gears, bearings,springs etc. Sometimes moisture and dirty air can get into a pneumatic tool and cause problems. Clean it thoroughly and hopefully it will fix the problem you area having with it.
