Lyman 45 problems Lube comes out the top

[jh45gun]

I bought this a while ago at a gun show for 20 bucks (Lyman 45) I just tried it tonite and the lube wants to come up past the pressure nut towards the top of the reservoir. Got any suggestions? I have a 450 too but I have that set up for my 45 colt bullets and would like to use this 45 for my 30 cal bullets.

Can you put an O ring on the pressure nut? I forget if they have the cut out or not. I had the same problem and wound up putting the pressure nut from a 450 on it and it works great for me.

Yep, back out the pressure nut and see what style it is:

Nut with wide packing wad washer material=old style/order a new style nut from Lyman for a model 450.

Nut with two grooves= new style-replace O-rings or add if missing, nothing special as the O-rings can be found hardware stores.

Ease up on the pressure on the ratchet handle.

Thanks guys I took the nut out and it is the old style I guess no grooves for O rings and NO material on the side either just bare metal on the side with a lip on the flat side and kinda dome shaped on the other side. Just for future reference which side goes down when I get the new one since this was used not sure if it was even put in the right way.

I use to put one wrap of cotton twine around my old syle pressure nut, as a packing, to imporve the seal. That worked fine for me, but I eventually got the new style nut, when I found that they were available.

For future reference, the domed side goes down.
But it sounds like you have an incomplete pressure nut.
The steel nut should be wrapped in a brass sleeve.

Also, if you do go ahead and by the pressure nut you may wish to invest in a new pressure screw in the 450 style as well. It's a more robust design than the original one and cheap insurance.

Thanks CM, never knew about the brass sleeve. That would explain my leakage as well.

[jh45gun]

Good to know and yea there is no brass sleeve. I ordered the nut and the two O rings today at the gun shop. I could order direct but he orders from them all the time and this my order goes along with his stuff so shipping does not suck for one or two items. I am going to try a piece of leather where the brass sleeve goes until I get the new nut and O rings. Either it works or it does not.

[jh45gun]

Well to get by I cut a strip of leather and went around the nut 90 percent of the way since the leather was a bit thicker then it should have been. This worked well enough to get the lubing done I needed with the bullets I wanted to relube as they were done by some one else and given to me and they had gaps in the lube. Worked well enough until I get the new Nut and O rings.

When you refer the the "pressure nut", are you meaning the piston? The original has an expanding brass ring on the O.D. of the piston. I replaced mine with the new style with 2 o-rings. Works great. The old one would just spin around in the cylinder as I turned the stem. The only way I could stop it was if I would put pressure on it with a screwdriver while turning the stem. I guess it was just wore out.

[jh45gun]

Yea that's the part I mean.

I have a oring (small) on my old style nut just below the ridge and the 2 pins. Will get me by for awhile and it works.
