I have in my hands a Sheridan multi pumps in .20 caliber.
It has been in my wife's family and ended up in my hands.
I suspect it is from the 90s but that's all I can say.
I am looking for help identifying it because it doesn't hold air anymore and I'd like to fix it for future generations to enjoy it.
Because it needs fixing, if any of you has ideas what parts I should look for, as well as instructions for taking apart etc... do not hesitate to chime in also!

LEFT SIDE being about equal position to the loading tray will be 4 numbers.
They are put in REVERSE of the year manufactured.
AKA: 1691 would be 1961
-
Thanks Scott for your help!
I did not find those 4 digits on the left side. I'm adding a picture of what is present on the left side. Could what I am looking for be under the stock ?
The garbled numbers on the left part of the picture are in my previous post, labeled as "serial #". It is a 6 digits number ending in 84 or 94 (I can't read those easily, the stamping was not perfect.)
-
This should be a later 80's model as evidenced by rounded top of the breech ( earlier would have a distinct flat with lines cut in it ) the matte silver finish and being drilled and tapped for a William's peep.
You could order 'em with the peep earlier on, but you would not get the standard rear sight with it, post '84 or '86 they all came drilled and tapped for the peep sight.

You have a Sheridan Silver Streak, made in 1984 per your serial #431284 and Crosman website date listing. On the Web are numerous tutorials on repairing these but a good one is: http://www.ujays.net/sheridan-manual.pdf (http://www.ujays.net/sheridan-manual.pdf)
You may be able to revive it with a dose of non-detergent oil added to the pump area, but ideally you'd replace the pump cup and internal seals. This requires a 'special tool' to remove the valve parts, which is available from a few sources (Google 'sheridan streak valve tool'). Seal kits are also available from several sources including Mike Baker on this forum.

You should stand it up in a corner with some non detergent 10w30 motor oil for a few days and see if it revives the seals.
-
Thank you so much!
I had no idea info still existed about this one, I just thought to ask here when I saw it.
I'm on it!
-
The "Older" ones have the 4 numbers stamped on the receiver at loading tray area & NOT on the main tube.
Sorry If i misguided you being I know nothing of the newer guns.

Hi Ronan.
Your Vintage Sheridan Silver Streak has the rocker safety.
It appears to be already drilled & tapped for a Williams Peep sight.
That's a real Nice Rifle you have.
Best Wishes - Tom

Scott, All I can say is that I know next to nothing myself, and I did appreciate you chiming in to help. At the minimum, it encouraged me.
I just came straight to the forum to ask questions without doing my homework first. A Bit like asking how to maintain my air gun without opening the manual it came with.
I have looked at a video on how to disassemble an older model of Sheridan and did the recommended oiling for moving parts using a dab of air compressor oil on the moving parts.
I did pump it and felt resistance building up to a point then plateauing. instead of dry firing it after that, I decided to chamber a pellet from a tin that came with it. When I opened the breech, I clearly heard the air leaking. The sound stopped once the pellet was chambered, but I suspect it just kept escaping through the barrel. There was enough air remaining to send the pellet at roughly 25 yards and heard a thump on the plywood piece I was aiming at.
I'll be back after looking into it some more
-
Hi Tom,
It looks like it indeed. I did not expect that.
I'm now looking into fixing it somehow.
I do not know how it performs at peak power, but with its leak, it is still a very nice plinker. I can follow the pellet with my eyes though. BB style.
-
" Oldair " is correct on the I.D. Use NON detergent 30wt motor oil ,[ transmission fluid will also work ] Lube the pump cup piston area again with several drops. Pump it a little & dry fire it. Pump twice & leave it alone overnight.
-
Ronan, just so you are aware...
You have what is considered by many to be the Holey Grail of Vintage pumpers.
I would try the "lube, pump, shoot, pump twice and let it set" method several times before taking it apart.
If it fails to come out of hibernation, they are not hard to reseal, if you are mechanically inclined.
Be warned..... It does take a special tool to disassemble the soldered in valve, and because it is brass, you can cross thread it on reassembly.
So don't go in all "hammer fisted".. take your time and be cautious.
Above all...
CONGRATS!!!
-
At peak performance you should need no more than 4 pumps for plinking and small pests like rats or sparrows.
Even 3 will have great power for plinking up to 15 yds.
A full 8 pumps will have excellent power, it'll take some real effort to get there and you'll rarely need it but it sure can deliver.
It sounds like some oil and some use just might get it going again, if not 100% full power ot will likely still perform very well if it stops leaking.
-
Nice gun...
Once you get it up and running, always store it with a couple pumps in it. That will keep the seals nice and tight.
-
it needs a new valve stem
the oil treatment may cause the seal to swell and seal but it really needs a reseal
you can replace the stem with a discovery stem a modified 2240 stem(piercer part removed ) an as2250 king rat stem or a benjy 39x stem
i've used all of the aforementioned stems in a c series
-
Thank you everyone for chiming in and helping.
I have looked at the kits available on PA as well as those from Baker Airguns on E-Bay.
Baker Airguns has an offer that includes the tools, and that is a tempting one.
I'll see how it goes, but I am looking at getting a total professional overhaul at the moment, as this Sheridan is totally worth that care.
I nonetheless approached Jonathan Brooks, who is the person behind NorthWestAirgun in Sacramento and is very knowledgeable on Sheridans.
https://www.youtube.com/watch?v=zvTDiz5IE7o (https://www.youtube.com/watch?v=zvTDiz5IE7o)
He does not take projects at the moment, but sent me toward one of his friends in Fresno, less than 2 hours from where I live.
If that doesn't work, I'll do it myself slowly.
I was pleasantly surprised that I could lock the Sheridan with my right arm against my body and pump with my left arm easily. It did not create the issues I encounter with break barrels (bad right shoulder).
It is short, fits well in the hand, and a total pleasure to shoot. It is noisy to pump, though. stealthy use is not going to happen.
I did use air compressor oil to grease the pump mechanism, but I made the mistake to add a few drops through the air hole thinking it may help also. I learned after the fact that it is a big no-no. I'll be careful when using it. As I'm waiting on my Avenger, this is a mental health saver for me, besides the 'holy grail' part. I have big plans for that Sheridan, and they all involve significant use!
I may disappear from the forums for a while, I have a full tin of 500 Benjamin 14.3 grains that are begging me to take fly lessons. Who am I to say no?
-

Not the case where you are at today... that is exactly what it may need.
-
Thank you guys for your kind (private) offers of assistance! I do appreciate.
I have been referred to someone operating a Crosman 'service station' within reasonable distance from where I live. He does work on Sheridans and has the seals in stock. After some basic communication, the plan is for me to drive and drop the Sheridan at his shop and he'll work on it while I wait. It looks like I'll get to drive back home with it the same day.
With my recent less than stellar experience with shipping, I do prefer greatly this option to sending it. Also saves me the aggravation of making an earthquake resistant parcel. This is why I am going that way.
To Scott: it does make sense, and I feel better now.
-
Sheridan service "while you wait"?!
That is FANTASTIC!!!
-
Sounds good. You are fortunate to have a repair person close by. The B-S pellets will shoot OK & are good for hunting, but JSB Diabolo Exacts, 13.73 Gr. are more accurate !
-
Depending on what the pellets are you got with the gun... they may be valuable to collectors as well.
Might want to hold onto them. ;)

YEP. Last year, I sold a case of those pellets in the red container , one at a time. That was long before the price went up, but I was still satisfied.
-
Scott, I don't know if it was sarcasm or not as this is a total first for me, but I find it fantastic indeed :)
This being said, I've been offered to actually be present and observe the repair being done. You can bet I said yes please!
I think I'll ask that person what else he does on airguns. I'm so pleased that I'm already thinking about what other business I could give him.
Steve, thanks for the info, I have taken note and I'll buy those.
I've never owned a .20 caliber in my life. I was actually super stoked to find a tin of .20 caliber pellets to shoot it with!
It did not come with any assorted pellet container.
It did come with an unrelated rectangular plastic container holding .177 diabolo pellets.
It'd be hilarious if that plastic container had any collector value. I would be surprised as it looks like a cheapo container, but I'll post a picture tomorrow if I have time.
-
No sarcasm intended.. I think it's Great!
-
Another thank you to all!
The air compressor tool oil I was using to lube it up is non-detergent.
After 2 days of light shooting and storage overnight with 2 pumps in, I cannot hear the air leaking anymore.
I just pumped gradually up to 8 times and shot. There is a definite increase in velocity and I can't see the pellet anymore.
I do not find the pumping to be difficult until pump #7. even for the last 2 for full power, I manage without real issue.
I did a string of 8 shots at 'full' power and did not mind once the pumping.
I am keeping the reseal appointment to make sure everything is fine and maybe do preventive maintenance. I want to meet the person. have the feeling I'll like this guy a lot.
The open sights are nice to use, but I am wondering if adding peeps might increase accuracy while maintaining the same level of fun. Peeps seem to be more in line with the style and age of the Sheridan. Red dots scopes don't feel right at all in my mind.
-
A peep sight is the way to go with this gun. Doesn't interfere with pumping, and the sights are low to the barrel, unlike scopes.
-
Peeps are absolutely the way to go.
I was always quite happy with the factory open sights on my '79, but I could never do this with 'em.

I have some with standard sights, peeps, red dot , & scopes. I like all of them !
-
Because your Silver Streak is already drilled and tapped... A Williams 5D-SH is a natural.
They just don't get any better for the "Bang for the Buck"

Let me know if you want one and we can work a deal after they arrive. They in stock at Midway and some other places too.
-
Another member stumbled across them a couple years ago... I have bought a few from them as I needed them. They will return to stock.
-
No problem, there are a few places that sell them for around $35.
I am grateful for the reference you provided, this is where the real value is for me: now I know I'll order the right ones!

The Sheridan has been overhauled by Chet Pauls from Fresno CA, a Crosman, Benjamin & Sheridan authorized Service Station, and man, is there a world of difference from before!
I spent some very nice 2 hours while he showed me how it is done and having some great conversations.
Chet in himself is a huge sale argument for me buying a Benjamin air rifle in the future.
Reviving the seals with a very small amount of oil worked to some extent, but during the overhaul, I saw how much the seals were crushed and hard.
It is a completely different air gun now. Like from a fun plinking airsoft to a serious tool I don't want to give to my son but keep to myself. That little silver streak is a jewel.
the pumping is also significantly more involved.
It should now be good for 15 more years of faithful services!
-
That is great news...
Now, put a pump or two in it when you put it away.
-
I've been told one only.
And that it's not really for the seals but more to keep condensation from happening inside.
-
Resurrecting the post shamelessly because I am considering parting with it and just started a new thread asking for input on what a fair price would be.
-
AND.... it is now mine. ;)
Thank you Ronan!
