Topic: Assistance with lubricating a Benjamin 20 Cal.  (Read 1816 times))

I am apply to shooting springers but while I was in Kalispell Mt this summertime a friend talked me into going to a gun show with him.  While at the show I picked up a real nice Benjamin twenty Cal at the gun prove.   Now I need to know what lubrication I need to employ and where I need to lubricate it.  Thanks, Alex

Really the only lube needed ........the hinges... Crosman pellgun oil...maybe a drib in the barrel.....sparingly
i would remove the bolt and only make certain information technology is not rusted..
Mayhap a driblet on the small o-ring at the front of the bolt..
Mac1 (on the internet and here) has his Undercover Sauce..

Another important matter to call back on pump guns like the Sheridan and Benjamin is to store it with
one pump. This keeps the discharge valve fully seated. I always kept i gentle pump in mine after every shooting
session. A driblet of PellGun oil on the pump piston seal every now and then is also a good thing.

A Crosman/Benjamin C9, or a C series Sheridan blueish streak ?

I sure would beloved to come across a picture of what you got.

To oil information technology, simply some SAE ND 10W30 motor oil on the pump cup and a drib on the pivot points is all information technology should need.

Thinking it's either a  a C9 or C9A since the OP refers to it equally a Benjamin?

The OP can exercise as he/she wants every bit well every bit the others merely, the drop of oil that goes on the rivet closest to the breech is plenty oil for the pump loving cup. Information technology will drift to the felt.
That is the warning for not to utilize too much oil.
Come across the photo?

Possibly.
I have known people who thought Sheridan was but a secondary line created by Benjamin.
I even saw a YouTube video talking virtually how Benjamin introduced the Sheridan line and showing a C9A that their uncle supposedly got as a kid in the 50'south.

Cheers to all the have replied to my thread.  It does have C9A Series stamped on the barrel along with 20 cal and what I have been able to find I am bold that it is Benjamin Sheridan Bluish Streak.  I bought information technology considering I wanted the wooden stock, not a plastic stock.  I'll get some pics later on in the 24-hour interval and postal service.

"the drop of oil that goes on the rivet closest to the breech is plenty oil for the pump loving cup. It will drift to the felt."  Frank in Fairfield,  I am not seeing a rivet near the breech.

That'southward been my become to for years.  As a affair of fact, I've been on the same bottle for years as well. It doesn't take much.

The OP can do as he/she wants besides as the others but, the drib of oil that goes on the rivet closest to the breech is enough oil for the pump cup. Information technology will migrate to the felt.
That is the alarm for not to use too much oil.
See the photograph?
Suit yourself.

When Frank says "the rivet closest to the alienation" I believe he is referring to the pin (which is i of the iii pivot points on the gun that demand lubing) that joins the lever link to the piston on the pump rod.  TimmyMac of Mac1 airguns recommends several drops of oil on that point, because the piston is a porous metal that soaks up the oil and slowly disperses information technology as you pump, keeping the gun lubed.  At that place is no felt on these guns similar on the Crosman pumpers.

So, one or two drops on the pin point up near the muzzle, where the pump arm (the function you hold onto) is fastened at the second roll pin, one or 2 on the lever link rivet (the "heart" point in the pic higher up, where the pump arm is connected to the lever link), and maybe five or half dozen drops where lever link connects to the pump rod piston.

The reason for more oil on that piston is, it slowly lets backlog oil into the organisation every bit yous pump, flushing whatever debris out of the gun through the valve, and out the butt.

Re-oil whenever those parts look dry out.  Do NOT use detergent oil like you lot use in your car.  The detergents volition harm the seals.  Tim'southward secret sauce, or non-detergent 30 wt. motor oil, or automatic manual fluid.  I think hydraulic fluid would work, as well.  Simply make sure there are not detergents.

I use Mac1's hugger-mugger sauce or 30 weight non detergent oil every tin or so. Benji'due south don't accept a felt wipe to agree oil so I put a VERY, VERY small drop of non detergent thirty wt motor oil or Mac1 Secret Sauce oil nether the air plunger when the arm is fully upwardly, I do this once every 100 shots or so. Oil in the chamber and valve is not a proficient idea, only a light film on the sides of the pinch tube helps with compression and increases the life of the seal. ---over again a very, very light film, don't overdo it, more is not better !

I likewise use a pocket-size drop of Liquid Wrench on the hinge points every tin or so. I apply it because of the micro molecules that may help keep the gun in tip acme shape for years to come.-- The Liquid Wrench thing is what I practise, I don't know if anyone else uses it.

I wouldn't employ the liquid wrench anywhere.  Information technology may migrate downwardly to and past the pump cup and crusade damage to the pump cup or any seals on/in the valve.  I know you said you only employ a footling bit, only why take a chance?  TimmyMac recommends Secret Sauce on all pin points.  That, or the ND xx or 30 wt. should exist good for everything.

William said he only uses "Liquid Wrench" on the pivot signal of the pump linkage and Secret Sauce on the pinch ... to each his own.
 I use Marvel Mystery Oil on all.
Even have a five gallon saucepan of reddish "Turbine Compressor Oil" from a Establish I worked at that closed and u.s.a. Maintenance guys divided up the "consumables" that I volition utilise next... Life time supply!
 Also...  am thinking almost using it information technology my Y.H. Compressor adjacent change out. (only that is a whole 'nother topic I will get feed dorsum on some mean solar day).

With a 5 gallon saucepan full, you should buy some little plastic bottles in bulk and gear up yourself upward in business organization. Might brand enough to finance that Model A Sheridan! Just accept to come up with a skilful name for information technology.... something with "Hoosier Daddy's" in it
