Crosman 1377 Piston And Valve Mods




What do you think about this video?

Aldo Rini: Hey Mike, great video..really enjoyed it. I have 1322 and wanted to add this modification. Where can you order this valve?

Marc Hills: A lucid, well-presented explanation of the 1377/1322 piston/valve operation, and exactly how the modifying them can increase performance. Nicely done and thank you.

J Martin: What are your best results with modified {all out/anything goes } 1377 ?? 

bomartin: thank you for your video, the information was great, 

callofdutyguy9: Where did you get your FT piston and FT valve? And can you make a video of how to install everything

Bob Bob: please turn our xxxxxx music off so we can hear you

lige risner: what do you think about the high performance pump valve for crosman 1377&1322 that's for sale on ebay it is not flat top but is ported and has more room for air in side

Daniel A: U sound like marky ramone

Airgun n00b: Your accent makes me miss the east coast

lige risner: ebay is the best place to get up grades for all of crosman air guns if any one is still needing them

hardway106: Wicked cool video Mike..helped out alot with my 1377 Mods.. Thanks for showing us..

mark long: how big did you drill hole? 

MrEricdgreat: I like your video, I got one of the first gen 1377 and I hear air escaping out the barrel can you tell me how I can fix it does not hold any pressure ? and I also pulled the handle off and a very small spring fell out I have no idea where it goes can you help?

PopeMouse: Great video man! This really helped me out. :) i just have one question, what site or sites do you get your parts from?

miketheknife2: Yes sir your right just the barrel and bolt prob are different.

BeastieG13: thanx Mike !

Kel-chan: cant you just file and sand down the piston to get a flat top? what happens if you use the stock plunger with this flat top?

miketheknife2: @AndyAbez lol

Psycho12345123: @miketheknife2 yeah the farthest i shoot at the moment is only 10-15 yards

F13rce187: @miketheknife2 so if I bore the valve will it increase the fps or get a flat top piston

SpiderMack: im installing ft piston n valve do i need to add 2 drop pelletgunoil down the hole of the valve? i just want make sure thats correct is it? thnx

kingfish4488: I have an old style 1377 are they any mods. worth installing on it? It needs to be rebuilt its not holding pressure,also who is a good parts seller. Thanks Rob

macabespeed: Could you maybe do the old JB weld flat top piston? Grind the stock valve flush and maybe fill the center of the piston with epoxy? obviosly youd have to machine and polish the jb, but what are your thoughts? did this type of mod (epoxy) to a beeman p17 and it REALLY worked well....

miketheknife2: I wouldn't do it that way the epoxy could break up and damage your gun.

miketheknife2: @0akie13 Thanks and your welcome I have fun making them.

Psycho12345123: @miketheknife2 can you make a vid on how to drill the hole out and make the fps higher?

thatbme35: hes not that rude for dealing with dumb freaks day end day out. yes hes short with folks but i got a great 18in. 22cal. barrel frome him for cheap.i ordered my flat top piston valve set from airgunsmith dotcom they sell a great set.

GHOSTTOYS: ok but do a flat head get more air in or does it pump with less then 10 time , i personaly have moded my 1377 (canadian) by pluging the hole in the back and drill the valve exit and drill the jonction between the pump and the barrel it have alrady give me more speed and strength , can it get faster and stronger with the pump mod ?

Nate9595959595959595: @miketheknife2 where did you buy all the mods? like the pump and the barrel?

miketheknife2: Thanks man i'm glad you liked it.

miketheknife2: Mellon air . com

Patrice Beaulieu: My air started leaking after putting oil in it. I managed to temporary fix it by unscrewing a little bit the screw right before the trigger. The one that hold the bottom. If its too thigh aire starts leaking when I pump . Do you have any idea how to fix this ??

miketheknife2: The cone will keep them from touching but the flat top set up will touch each other.

Patryck Oliveira: Very nice videos guy!Congratulations from Brazil!

miketheknife2: @jonnytheninja2R You need to use emery cloth and smooth all of the sharp edges inside the tube.

Eadwine17: i installed the flat top valve but when I pump the gun there seems be air leaking out.. can anyone help me?

Victor Gonzalez: can a stock piston and valvle be modded to convert them in flat top? and you mention that i need to make the hole of the valvle a little bigger what drill bitt i must use?

GLC jonsan308: Do you know how to get the piston and valve in without cutting them in the tube?

miketheknife2: Mellon air . com

Nismogtir1: this is a vry informative video=)

MagnoliaX12: What are your thoughts about converting the compressed air cylinder to use compressed air from a hose? Basically remove the pump lever and run the hose down the barrel under the pump arm. Is there enough meet on the end of the cylinder to thread and attach an adapter? I have a Sheridan .397 that I want to do it too but not sure if it would work.

hazza2014: hi can you make a video resealing the 1322 and 1377 crosmen pistol thanks hazza

miketheknife2: @BlazyNonVevo It's very easy to take apart pretty much remove all the screws be careful of the rear cap it's under spring tension, and remove the pin that holds the pump arm in.

miketheknife2: @0akie13 Sure can just dont go to big.

PrinceMustDie666: b great comment, so relevant, please comment more

miketheknife2: @victorgonzalezd1 I just 2 sizes bigger

Xxoo0o0o0ooxX: Have you ever encountered a aluminum valve for the 1377? I have it still worked good I still bored it out. But I really did not like it that much seemed cheap you know? Well anyways I have only seen one like it maybe they were trying to cut cost's.

drazmainianjew: Were did u get ur mods from

0akie13: Hey could use a drill bit and try to enlarge that hole in my valve to increase airflow or would that ruin my gun? Any help is appreciated

BeastieG13: how do ya take the top cone off the valve?
