Wow I’m glad i came across your video because I’ve been wanting to repair this rifle ever since it quit pumping many years ago. I got this rifle new back around 59 or 60 and shot thousands of pellets thru it. I always kept it cleaned and oiled right after using it and it functioned beautifully. However, it was packed up in my parents crawl space before i enlisted in the USAF. I retrieved it when my parents moved and it would no longer hold air when pumping it. After watching your video I plan to hunt down a replacement seal kit and repair it. After that i would like to find a way to replace the stock sights with an adjustable peep sight used for target shooting. Thank you so much for putting in the time to make this video. You did a great job explaining everything and showing close ups of hard to see small areas. Thank you I also subscribed. All the best, Don G.
Thank you so much for taking the time to share your expertise and Knowledge. My Father gave me my Crossman pellet gun when I was 12 years old. My Mother kept it in a closet up until her death in the early 1980's. When we cleaned out her house I brought it home and put it in the gun closet. I pretty much forgot about it until a couple of weeks ago. My grandson is now 9 years old and has expressed a desire to learn how to shoot. I went to the gun stores here in town and could not find any 22 LR ammo. The only thing I could buy was bee bee's and pellets. I bought a can of pellets and we headed out to the desert. When we got there, the pellet gun didn't work. There was no way that I thought I could get parts for a 51 year old pellet gun. I googled Crossman 140 repair and found your video. I just finished the rebuild after watching your video multiple times. Once again thank you so much for sharing your tallents!!
Thanks for making and sharing this video. I was able to rebuild the rifle passed down to me from my grandfather. Good to have it working again, thank you!
Just completed replacing the seals in my 140 from the originals which are approximately 50 years old. It works perfectly!!!! Thanks goes completely to this video! Thank you. My 140 has the safety switch; to remove it you need to position it half way between safe and fire; from there slowly wiggle it out while pushing the opposite side. You can use a screw driver to push the small metal rod pushing up against the safety switch. Keep wiggling and it comes out without any real effort. Thank you again for these 2 amazing videos!
Thank You !!! I have had my 1400 since I was a kid, (im 40 now!!) It was my first gun I ever shot...It still works and has a lot of power !! I do need to replace the O rings, I shot it in the cold the other day and after 10 mins,it wouldn't hold air... Thanks to you, I may be able to do it! I will keep you posted....
I have the Crosman 1400 and did not hold air. I was able to get O rings and the quad seal with the brass cup from ebay. I installed everything and have been using it for about 4 years now trouble free. I also pump it once before I store it. This rifle is very accurate and powerful and very good for hunting small game.
Hi, Thanks for posting this video on the disassembly and resealing of the 140/1400. I have been looking for a 140 or 1400 for my small collection. It doesn't look to hard to repair or to service. Problem now is finding one for sale in good condition. Thanks again, Todd
Thank yo very much. I just re-did the seal on my Crosman 1400 Bolt Action. I watched both of your videos. Very helpful. Just tried the gun. Very accurate, love it. Only thing I'm not crazy about is the Valve Spring. its weak in the middle. Hope it lasts awhile. I wont be shooting it much. My Dad just picked it up for $2 at an estate sale. Great find.
Long story short, in the process of rebuilding my childhood pellet gun I lost a part. It is the EXHAUST VALVE RING 140-56. Crossman 1400 with brass valve. I would be glad to pay for one if I could find one.
I've got a 140 and one big difference is with the trigger assembly. It appears your trigger assembly is attacked to the stock. On my 140 it's attacked to the bottom of the pump tube and the stock pulls off over it - once you remove the safety switch which is part of the trigger guard. The rest of your video has been a god send for me. I'm 99.9% sure the issue with my 140 is the Port Transfer seal. Luckily I got a new one in the rebuild kit I bought. Thanks for making this video !
MANY thanks litl70. Got my seal kit yesterday. Spent this evening working on it and now I have an apparently functional SEARS .22 cal pellet rifle. I say "apparently" because it pumps up and shoots now, but I have no pellets to test it with. I assume since air comes out the end of the barrel it will work. Now to get some ammo and test the accuracy. Again- many thanks.
I would like to say thanks to lit170 for ding these two videos showing how to repair the crosman 140,did mine today November. The 14th 2017,came out great,now I need for you to do a video on the crosman 109 town+country jr and I will be set.
Hi. Good video. I got my 140 when I was 12 years old in 1967. I still use it to knock down sparrows and black birds in the back yard and like the heavy punch of the .22 cal. pellet. The rifle looks almost new but the seals are getting real bad. I'll do as you suggest and get a seal kit and go to work on it. It says "Made in USA" on the rifle and I will keep this one going and pass it on... Thanks.
Thanks for the video. It helped a lot. I've re-blued and rebuilt my crosman 140. It looks great but won't fire. The valve pumps up and holds pressure but the trigger doesn't release it. Any ideas? Have I got a piece in backwards?
Great Video you did here. I have had my Model 140 since I believe between 1960-1962. My grandfather purchased it for me. I am almost 63 myself now. Most recently tried to pump it up but it will not hold air so I purchased a kit on Ebay after watching this video. I didn't even know parts were available. Once again thanks for doing this video. Back in the day I remember this 140 being a powerful air rifle. Can't wait to shoot it again after all these years. Just have one question. Do the new O-Rings need to be lubed after installing? If so anything in particular like a little White Grease? I see they make a Crosman oil. All I remember oiling the gun with back in the day was 3 and 1 oil or WD 40.
Litl70 Really nice video thanks for that I have a 1400 trigger in the stock and rebuilt it all new orings and nylon seal and quad seal already installed, new cup seal for pump arm. It pumps fine but seems like air passing through valve. any ideas what could be happening? thanks Eddie
Great video, it is just what I started to rebuild, one question what is a quad ring? and how do you get a square ring? don't know wherwe to look for one.
Excellent video! I have a question on replacing the quad ring in the poppet valve. When I look at the end where the quad ring goes, there appears to be a hard plastic piece flush with the brass poppet valve. Does the washer go under this plastic piece? Also, if I sit my new washer on top of the hard plastic it is noticeably smaller in diameter. Thanks for any help you can give me! Dave R.
My Crosman 140 ,1966, has a tang safety on the trigger system if that's any clue, but I pulled the trigger box one time and found the sear to be badly worn, resulting in a lot of trigger creep. Is there a way to fix this? I know an old machinist, but don't know if he would be able to make replacement parts. I recently found my long lost repair kit and hope to do a rebuild with the aid of your excellent vid. That rifle was a real tack driver in its day and is still my favorite, even though it's been sitting in its original box in a closet for many years, having lost its ability to hold compression long ago. BTW, do you recommend lubricating all the seals and other components when re-assembling the gun? Which lubricant do you prefer, that will not harm the seals/o-rings? And how often do you recommend oiling the internal mechanism, with the same or a different lubricant? If I can restore this little gem, I would like it to be good for the rest of my life, and maybe those who come after. Thanks.
I have a Crosman 140 that was given to me by my late father as a Christmas gift when I was 14. This 50 year old gun is very important to me. It doesn't pump up. Watched your videos several times. Very helpful BTW. First installed a seal kit. Same result so I got a new pump rod assembly with new cup. Still nothing when trigger is pulled. My PTFE check valve isn't shaped like the one in your video. It is tapered on one end only with a smaller diameter protruding from the taper. The other end is flat. I installed the tapered end into the valve body with the spring against the flat end. The check valve sticks in the valve body and I have to force it out through the intake port with a tip cleaner. Could the sticky check valve be my problem? Have had the gun apart 3 times and I'm stumped.
Thank you for this!! I have a 1400 I grew up with that will no longer hold air even though its oiled, you mentioned about having to machine parts... will this be needed just to re-seal? It worked great all my youth until it set unused for years. Now i'm 41 and want to use it to teach my kids to shoot. :)
Hi, thanks for your video! My gun is now operational (mostly), my issue is that my breech plug screw is stripped, may I ask what replacement hex bolt did you use? What millimeter / length ? Thank you!
I followed the video but now there's a leak so that it won't push the pellet out. I have the poly tubing washer on outside the barrel. Could it be the washer clear at the rear in the hole where the videographer said he replaced a rubber washer with a lock washer? It pumps up but when fired air leak out somewhere making the gun worthless right now.
Thanks for the video, I am rebuilding mine that I recieved Christmas of '79, was wondering if the handle on the bolt comes off from losening a screw in the back of the bolt as shown on my schematics. However there really does not seem to be any type of screw that I can see. Can I replace the O ring without removing the bolt.
Any suggestions on where to get new seals? I know you said that it was difficult. My 140 looks to be in great condition, it was my grandfathers back in the day. There is no compression upon pumping so this leads me to believe that seals are bad.. Any suggestions or recommendations before a rebuild would be much appreciated.
Wow thanks for the quick reply, the schematics that came with the seal kit show a set screw with a slotted head, but I looked really hard at the back of the bolt with good lighting and a maginfying glass and mine sure isnt a slot head, maybe its a hex but really small, I will try and see if I can get it out tomorrow. Sure seems like it has to be a set screw holding that handle on. If I cant get it out, does that O ring on the bolt really effect that much. For all I know it still seals OK.
Thanks for the repair video I just got a 1400 22 cal I'm going to try to fix it with your help the rifle I have has the safety on the trigger. (like the other rifle you showed ) how do i get it(the safety) off with out damage? thanks again for you time .
I actually have two questions: I have a crosman 140, the Roll Pin/Tube Plug Pin, Part # 140-30b has threads on both ends. I have seen these pins on e-bay but they have only one end threaded. do you have, or can you tell me where to get the appropriate pin for my gun. Secondly I have a crosman 180, and need the cap for the co2 barrel
Thanks!!! Do you sells the pump pistons that you make? I am rebuilding my father's 140 and would like to bring it "up-to-date' as much as I can. So do you sell the updated parts that you machine?
Thanks for the video. There is a lot more in there than I would have imagined. The air rifle I have says 1400 on the side and has the safety. It will not get pressure. I can't turn the safety from fire to safety and I can't get the stock off because the safety is in the way. So far I have resisted the urge to use force. Any suggestions would be appreciated.
Mine is different then that one took the hex bolt out but it does not come apart from the stock and the pump.lever Pin is rivited on. I can here where the gun leeks air its near the trigger group some where. I got it to fire twice but then nothing.
Hi I got the version with the safety on the trigger,I just cant get the trigger to come loose,out from the tube??? got a solution?greetings from the netherlands, holland
I can't get the knurled pin out so I can remove the pressure chamber. I have used a small punch and a ball pien hammer, but the pin doesn't budge. Any ideas?
Did the job yesterday but it didn't work out as I expected. The Rifle still doesn't hold air or air is not being pumped into the rifle possibly a (pump rod assembly) problem. My Check & Exhaust Valve Assembly is the Brass Valve different from above. It has the Teflon seal that doesn't require a O-Ring. I replace all other O-Rings except the one that is suppose to go inside of the Exhaust Valve Cap. Mine being Brass does not have a O-Ring inside of it. It seems to be all metal as I scraped a little of it thinking there was a O-Ring at first but it was all metal from what I was able to see. Does anyone know this to be a fact? The exhaust valve Ring at the end also looks different then yours above and different from what I see in the downloaded Crosman Manual for the 140. The one in my Crosman manual has the threaded hole in the center part of it an then the tube becomes smaller. The one that came with my Rifle when looking at it has another smaller section tube in front then the tube is higher in the center where the threaded hole is located and then the tube is smaller again and of course it fits right over the exhaust valve cap. Other then that everything else seems to be the same as in the video above. One other thing I encountered is that I had a problem getting the valve pin out of the bottom barrel as it got lodged standing verticle stuck in the barrel. I believe this happened because when unscrewing the bottom wood stock nut and washer the complete stud unscrewed out of the bottom barrel and brass valve. It was a pain in itself to get it the valve pin out of the barrel and it looked to have done some scoring inside the bottom barrel. Any help or suggestion would be appreciated as I seem to be stumped.
Ok 8 months later after putting the 140 away I decided to do a little more research. I was wrong with my last post thinking there wasn't a O-Ring in my Brass Exhaust Valve. Took the 140 a part a 2nd time and felt inside of it and sure enough what I thought was dirty brass was a Exhaust Valve Inner Seal. What a pain in the neck to dig it out I have to say. It was as hard as a rock and took much picking with the aid of a very small flat bladed screwdriver using it as a pick. Got it out in pieces until the remainder half or so came out pretty much whole. Cleaned the inside out with Q-Tips and Alcohol. Wasn't so bad getting the new one in which came in my seal kit I purchased 8 months before on Ebay. Didn't use any lube on the inner seal but put some Super Lube muti-purpose Teflon Grease on the other O-Rings. Put everything back together and now the 140 works. Don't know how powerful it is today compared to back during the early 60's when I first got it but loaded up a pellet and shot it into a piece of 2x4 at close range inside and it buried the pellet in the wood so I am assuming it is good to go. Going to leave it with 4 pumps of air overnight to see if it holds the pressure. Want to thank (lit170) who made this Video available. Without it my 140 would still be sitting in my gun cabinet. I should mention that I also found info on the GTA forum that helped me with my piston that I also knew would need to be replaced. Forum member Mac1 there is also a Vendor who sells a Flat Head Piston Rebuild Kit for Early Crosmans for $9.00 plus shipping as of this date. I purchased the kit and it works perfectly as good as new and probably better being next time there is a problem all one needs to do is change out a piston O-Ring instead of replacing the whole piston.
Hi I have a Crosman 140 22 cal taking it apart to fix for my son which is a very important gun to him.. I found that the pop off valve is missing how would I get replacement parts having a hard time finding anything would just buy him a whole nother gun but this one is special I must fix it would appreciate any help thank you
Only thing I did not like was you getting the valve out with the metal rod with nuts on it. It would seem like a good was to scratch up the tube to where the piston would not get a good seal.
when you "Machine a New Piston...And Add an O -Ring ....How do you re- attach the pump Rod behind it that attaches to Pump Linkage? Y'ou can never separate Piston from rod without Ruining something.....unless you somehow affix a nut(or two) to bottom of piston with same threads as what was on the rod!

Great video and tutorial my friend! Thank you for posting!
I have a 1400 and I need to replace the O rings. It no longer pumps!
Thanks for putting this video online!
Thank yo very much. I just re-did the seal on my Crosman 1400 Bolt Action. I watched both of your videos. Very helpful. Just tried the gun. Very accurate, love it.

Are there any big differences in the air valve between the old 140 rifle and the new 362 rifle?
Is the volume about the same?

Do you know where can i get after market slider with a handle
Did the job yesterday but it didn't work out as I expected. The Rifle still doesn't hold air or air is not being pumped into the rifle possibly a (pump rod assembly) problem. My Check & Exhaust Valve Assembly is the Brass Valve different from above. It has the Teflon seal that doesn't require a O-Ring. I replace all other O-Rings except the one that is suppose to go inside of the Exhaust Valve Cap. Mine being Brass does not have a O-Ring inside of it. It seems to be all metal as I scraped a little of it thinking there was a O-Ring at first but it was all metal from what I was able to see. Does anyone know this to be a fact? The exhaust valve Ring at the end also looks different then yours above and different from what I see in the downloaded Crosman Manual for the 140. The one in my Crosman manual has the threaded hole in the center part of it an then the tube becomes smaller. The one that came with my Rifle when looking at it has another smaller section tube in front then the tube is higher in the center where the threaded hole is located and then the tube is smaller again and of course it fits right over the exhaust valve cap. Other then that everything else seems to be the same as in the video above. One other thing I encountered is that I had a problem getting the valve pin out of the bottom barrel as it got lodged standing verticle stuck in the barrel. I believe this happened because when unscrewing the bottom wood stock nut and washer the complete stud unscrewed out of the bottom barrel and brass valve. It was a pain in itself to get it the valve pin out of the barrel and it looked to have done some scoring inside the bottom barrel. Any help or suggestion would be appreciated as I seem to be stumped.
Ok 8 months later after putting the 140 away I decided to do a little more research. I was wrong with my last post thinking there wasn't a O-Ring in my Brass Exhaust Valve. Took the 140 a part a 2nd time and felt inside of it and sure enough what I thought was dirty brass was a Exhaust Valve Inner Seal. What a pain in the neck to dig it out I have to say. It was as hard as a rock and took much picking with the aid of a very small flat bladed screwdriver using it as a pick. Got it out in pieces until the remainder half or so came out pretty much whole. Cleaned the inside out with Q-Tips and Alcohol. Wasn't so bad getting the new one in which came in my seal kit I purchased 8 months before on Ebay. Didn't use any lube on the inner seal but put some Super Lube muti-purpose Teflon Grease on the other O-Rings. Put everything back together and now the 140 works. Don't know how powerful it is today compared to back during the early 60's when I first got it but loaded up a pellet and shot it into a piece of 2x4 at close range inside and it buried the pellet in the wood so I am assuming it is good to go. Going to leave it with 4 pumps of air overnight to see if it holds the pressure. Want to thank (lit170) who made this Video available. Without it my 140 would still be sitting in my gun cabinet. I should mention that I also found info on the GTA forum that helped me with my piston that I also knew would need to be replaced. Forum member Mac1 there is also a Vendor who sells a Flat Head Piston Rebuild Kit for Early Crosmans for $9.00 plus shipping as of this date. I purchased the kit and it works perfectly as good as new and probably better being next time there is a problem all one needs to do is change out a piston O-Ring instead of replacing the whole piston.
Thanks.Great little guns eh?;-)
What does that smooshed plastic washer do?

I have rebuilt it twice...It pumps up fine but does not fire. Any chance I can ship it to you and pay you to fix it?...
Do you also do repairs for people?
Yea but I was wondering if there was a way to tell which seal is messed. Up so I don't have to go through the trouble of changing every o ring in. It
Hi i got a Crosman 140 at an auction for free and I dont know why but when I pump my gun up it doesnt keep the air in it so what should I do.
Only thing I did not like was you getting the valve out with the metal rod with nuts on it. It would seem like a good was to scratch up the tube to where the piston would not get a good seal.
when you "Machine a New Piston...And Add an O -Ring ....How do you re- attach the pump Rod behind it that attaches to Pump Linkage? Y'ou can never separate Piston from rod without Ruining something.....unless you somehow affix a nut(or two) to bottom of piston with same threads as what was on the rod!
You need a clarify that themetal ring is not part of the quad ring, and not to pull a metal ring out when you pull the quad ring out
Just FYI, it was a set screw, 2mm hex.
How do I remove the safety?
never mind...i kept reading
