I am repairing an 880 for a friend and I am in need of some sealing parts.
I need the seal between the barrel and breach, all of the pump o-rings and the elastomer spring. Are these parts available from an aftermarket source I know I've read that Daisy no longer supports them but somebody else does. Who is that current supplier?
-
It's a metal breach.

Sorry I posted to hastily I thought this was going to be tricky to find but then I found ronno6 on ebay has everything in one handy kit.

You beat me to it........
I do better direct....

I was going to suggest him. He's here on GTA as well!

I appreciate it.
I do have one question I noticed in the description it mentions a small o-ring that is no longer included unless requested. What is that o-ring for?

That is for the valve stem inside the hex (or round if real early) valve body.
Seldom goes bad; almost never used...

Okay cool. Yeah I don't want to take that apart. This one's round so pretty old I guess.
For convenience and since I'm not really that worried about the price I'm going to order through eBay or more accurately my wife is going to. 😁

Yup. I see that.
It will ship tomorrow.
Thanks!
Too bad yours is too old to do my trigger upgrade...
It woulda had to have the flat spring which yours does not....

I have a new one I am going to use your trigger on. This is a friend's gun. I am trying to get it back up to par for pesting. It's smooth bore but my friend shoots under 10 yards so it should be sufficient.

The kit came in and I'm just putting it together and there's only one thing I don't see where it goes.

I'm thinking it might go between the seal and the aluminum piece but I'm not sure why it would be needed.

I think I figured it out after some research it's the plastic backup washer for the foam wiper.

Unfortunately I keep losing pressure somewhere.

Is air escaping past the exhaust valve?? (out the barrel)

I'm not totally sure it's quite erratic. I shot about 5 or 6 shots that felt perfect and then the next one at 10 pumps the bb rolled out the barrel.
-
I think the pump is leaking. It sounds like it's hissing around the pump shaft area as I pump it but not very consistently.
-
I probably should have replaced the valve shaft seal. All the rubber in this gun was brittle. The polymer spring splintered when I compressed it to remove the pin.

Put a drop of oil in the valve stem and see if it bubbles when yoo pump it..........
I have those O-rings, as long as you have a hex valve.....I do not have one for the real early round valves...if bad, you will need to replace.....
Your bumper was better than most...typically they have turned to goo..........

This valve is round. Are replacements available?

Sometimes I see bubbles but not every time. I think it's leaking somewhere else too.
-
I think it's the valve. It seems to seal if the shaft is spun a certain direction.
Can I use a hex valve in place of the round one?

I am stumped. It just doesn't pump up. For a while it was not pumping and the pump arm was springing back with air pressure like the seal between the pump end of the pump tube and the air chamber end was not holding at all so I disassembled and inspected everything and wiped off some of the excessive oil I had put in it when I assembled everything initially and then reassembled it and the pump handle springing up problem went away but it still doesn't pump up. Just dry firing it in the house it just doesn't have that pop like my new one does. Got a new ronno6 seal kit and valve in it. It's got to be something I'm missing but I just can't seem to figure it out.
-
Give it the soapy water test.
You can do that without having to reassemble the receiver and stock.
That'll let you where the problem is.........
We'll go from there..
-
Well I haven't done soapy water yet but I pumped it up to 10 pumps last night which gave a week pop so I pumped it back up to 10 pumps and left it and it held so I got looking at things this morning and realized that when I cock the gun without the receiver sides on I noticed that the exhaust valve wasn't moving smoothly so I put a drop of oil on the stem and that fixed that I guess somehow I had not oiled it when I assembled everything so then I pumped it back up and I'm starting to wonder if maybe the new 880 actually does shoot a lot faster than the really old ones because it seems to be working reliably now it's just rather anemic compared to what I am used to.
-
I have never done that comparison.
There have been changes to the volume of the pressure chamber over the years.
I,too have felt that the newer 880 has more "pop" when shooting,but never chronied...
Ir is important that the inside of your pump tube is clean....
rubber bits stuck to the walls of the tube will cost you pressure, moreso at higher strokes.

It's spotless.
I found one problem. Possibly the only one.
I will post pictures when I finish reassembly and a quick test.

Unfortunately the new valve wasn't sealing
(https://i.postimg.cc/9QLPSWkg/IMG-20221025-101442504.jpg) (https://postimg.cc/YvmmLwMQ)
but my old one just had a bad stem seal so I swapped stems and used the new body with the old stem.
(https://i.postimg.cc/pVjwt7RJ/IMG-20221025-103017179.jpg) (https://postimg.cc/yWVQmLJD)
Unfortunately that didn't cure it. I got 3 good shots before loosing pressure completely and not even being able to build enough pressure to spit the pellet out the barrel.
It feels like once I blew the excess oil from assembly out of the valve it quit sealing.
I will do the soap test again later maybe tonight but now I have to go to work.

I wonder if the seat could be scratched or something that I can't see.

I guess that is air leakage.........not good.
How can I make it up to you??

Maybe I should send another valve, but I am not sure if there isn't another issue here......

I don't know that it's your part it might be the gun.

Hold off for now until I find out if it's the reciever.

I bought a 922 off ebay that would not seal. I tried everything, new seals, new poppet valves, cleaned to a mirror finish, deburred the transfer port, etc..... nothing worked. Now I'm just gonna pull the barrel and put it on a 1977 to make a 22 cal 1977. Sometimes I think the transfer port can get scratched to the point there's little hope. As a very last ditch effort you might try drilling out the transfer port to 0.125" then use a brass case chamfer tool on the poppet valve seat and see if you can remove the scratch in the TP. If that doesn't work you could repeat with a 0.14" drill bit on the TP hole and re-chamfer. If that doesn't work I would say the valve body is garbage. Again I consider these last ditch efforts that the end result, if not successful, will result in a completely ruined valve body. With that being said if its not sealing then sometimes its worth a shot because it works in some cases and a non-sealing valve body is already garbage.

I took the easy way out and dropped it off at the gunsmith. I have a couple future projects I want him to do so this is a good test run to try him out.

@freezypellets, did u get it working?

No I am stumped. I plan to send it to Rono6 to look at but I have been busy and broke so I haven't done it yet.

Sorry about that it's been a long year already for me.
I did need to check with you what all parts do I need to send I was figuring I can probably take the pump handle off and obviously the butt stock is there anything else you don't need??

Remove the receivers, front grips, butt stock and the barrel if it is the clamp on style. Send the complete pump mechanism.
That oughta do it.............

Thanks I'll try to get it sent next week. I have a busy weekend coming up I'm trying to get my sister-in-law's car running.

You can ditch the elastomer for a 1977 spring. A bit of a waste to toss all but the spring, but for $10 never have to deal with that elastomer again. I did it and glad I did.
-
Just the spring? Will the entire pump head not work? The standard PBL power mod??

It will not. The abutment is different. The abutment is retained by the ring in the tube and the factory piston is radiused for the ring where the 1977 is not.

My 880 seal kit is designed to be a form,fit and function replacement for the original 880 design seal.
This focuses on the chamber seal design.
It does not affect the piston other than to replace the original parts.
The 1977 piston and spring is not related to my seal parts.....
My kit includes the original Daisy "elastomer spring" which is a part I do not like......
The 1977 coil is a better design, but the piston is different and, though it MIGHT replace the original 880 piston, the face is different and will leave headspace
between piston face and seal abutment. It is unclear if this makes a difference in pumping efficiency or pressure.
The search for a suitable wire coil spring is ongoing.

Even with @ronno6 seal kit?
Ron's seal kit is way better than what Daisy originally provided but it is a design issue, not a part quality issue. Hey I love those old Daisys and have a few that are all original and restored (thanks for the replacement seals Ron). I have fun shooting them and remembering when I was a kid seeing them advertised and having my old 880. I still shoot them occasionally but if you are looking for power and/or a hunting gun your way better served with a new 880 or 1977. They make more power in stock form than any of the older guns. If you put the PBL mod on an 880 or stronger abutment pin in the 1977 they can make almost twice as much power as the older style guns. The older guns are the fore fathers to the new guys, and are awesome and deserve respect IMO. So I keep them and keep them as they were sold. I have one 87 model which is the same vintage I had as a kid (mine back then was an 85 model) and I have put one of Ron's trigger mods on it and replaced the elastomer with a 1977 spring. I am bluing the barrel and installed an LDC. That is the only older model 880 I have that is not factory stock. I did all that to the 87 because I hunt with it quite a bit. I love those years because as a kid I killed a truck load of squirrels with it and grew so attached to that gun it was like a part of me. I deer and small game hunted on farms with powder burners in the same time frame but never got attached to another gun like my 880. Back then I thought they would be the same forever so when I finally beat it up from all the rebuilds and banging around (I shot it probably 300 rounds a week) dropped it off bikes, trucks, etc... I threw it away thinking I'd just get a new one, but then I started college and then life took over so about three years ago I picked up a 1977 and lightning struck and here I am lol. I miss the metal receivers and pump handles so I salvage those pieces from junked older guns. I also REALLY like wood furniture so watch for advancements on that front from Ron and I in the future. I tried to get Boyd to add the 880 and/or 1977 to their line up but they said no new makes or models ATM. So the Daisy Gate boys will pick up the slack. If you are looking for a hunter send me a PM, I might be able to help you out.

Ok. Well I think I just need to temper my expectations. My 901, 880 both have your power mods and Mr. Ron's triggers and they are powerful and surgical. The 1977 soon to be 1925 should be as well.
I guess I thought the older model would be more powerful. It is WAY cooler with the metal handle and receiver. I guess I'll just get it shooting and leave it be. I will probably mod a spare rifled 880 barrel so I can shoot pellets. I'll keep the old smoothbore just so I can take it back to it's original state. Mostly original state.
