Daisy 880 Fix. 3 Main Seals Replaced.

If it is pressure failure, only change main Nitrile o-rings (2 SAE A113). If pressure still not there after this fix, watch my trigger video.

O-Ring only means break out the Danco Nitrile Treasure Chest. 2 #11 rings.

Any abnormality in pumping, means target the chamber seal. First try cleaning off the edges and wipe out the pump tube. Daisy Customer Care the most cost effective way for buying chamber seal.

Staying OEM means a Seal kit from Daisy reps which has the advantage of having wiper and chamber seal.

The tool I chose in this video is just for o-ring removal. A set anywhere between 15-20 dollars. A pick will work, but keep it away from new o-ring ring with it's sharp point. I've seen people use a razor knife. No way. Don't choose that.

Correction: Forgot to slip back on spring to retain pump handle. Just slightly pull up on right reciever (handle side, cock bolt back) and slip into holes before moving bolt forward and applying screws.
