Hi,

In Newfoundland here.

I recently retrieved my old .177 cal. Model 38T

from my parents' attic because my son is turning 12 this year and I wanted to give it to him. The problem I'm having is that it won't hold the CO2. I put the cylinder in and it just leaks out rapidly. It's possible the seals may be dried out. I oiled the gun but it doesn't solve the problem so they may have to be replaced.

2. The other issue is that, at some point, the threads for the CO2 cartridge retaining screw got stripped and my brother fixed it by putting in a nut. The retaining screw no longer has the "cup" that holds the bottom of the cartridge. It's possible that this means the cartridge either doesn't push up enough to make a seal or pushes too far and has damaged the nozzle that pierces the top of the cartridge. Either way, I'd like the threads re-tapped if possible and the retaining screw repaired properly.

I'm not comfortable with taking it apart myself so I'm looking for someone with experience breaking down this model. Can anyone recommend a qualified repairer?

Hi LesBudden!

Those older airguns are not very difficult to fix. Also as they are american built they use common o-rings (I fixed mine with a o-ring kit from Princess Auto). The only one that is different is the piercing pin seal and it could be obtained from Crosman (Gravel agency).

Check this site if you want to try the repair yourself.

For the stripped thead:

Good luck.

Murray he said newfoundland

there are several o rings on this model and the valve seal, most difficult part is if you end up removing the valve you must line up the feed tube from the valve to the piercing section or you will have difficulty closing the shell back up.

less is it leaking from the barrel or from behind the grips ?

here's two vid's for you to look at.

If you decide not to tackle the job yourself, being as you are out east I would reccomend contacting leanardj / Supermatic over on the ftcentral forum. Can't think of anyone else out east I would send something to for repair and not have to worry about getting a "bubba" type job. Might be someone else....but not that comess immediately to my mind.

Ace: Co2 leaks out from grip and through hammer.

I'm willing to send it anywhere via courier to get it repaired. Already checked with RCMP as to ability to do this and because the muzzle velocity is low I don't need any special permits.

so I'm ok with sending it via courier if within Canada and paying for it to be returned the same way.

I had an in-box reply suggesting a guy in Ontario who does repairs, email: webleyguy@gmail.com. I'm going by recommendation here so any feedback appreciated!

Hey R-Gun. Thanks for the links. I am not sure I can attempt those repairs myself because I have no access to or experience with the machining tools required. Though it's interesting that my own 38T seems to have developed the same two issues that Nick Carter's,(the blog author's), developed. Perhaps they are common with this model?

Seals are basically consumables, so there's a fair chance that any older pistol will need new ones, and any time you have threads in aluminium (or pot metal) that are used regularly you can bet they will get stripped sooner or later, so yes for sure, those will be common problems :)

How's it going with finding someone to fix it?

Jim
