Cleaning RT Pro Valve

[antwone_23]

Hi guys,

First off, great info at this site. I'm new to the forum and Automags. I just bought a used RT Pro, and while the outside of the marker looks pretty clean, taking it apart shows a lot of build up and rust. It looks like the previous owner didn't oil it much, if at all. The bumper seemed like a gummy lifesaver and had a strong stick on the bolt. So I'm going to take apart the valve as much as I can to replace all o-rings (and bumper), clean out the rust, and re-oil and grease.

I do have a couple of questions:

1. Would dropping some oil into the valve be enough? ..Or would it be better to split the valve halves and clean the insides? From what I read here on the forums, it's not a good idea to split the valves.

2. I should be using grease (and not oil) for the spring pack and regulator nut, correct? And I should put some grease on the threading as well? When I initially removed this part, you can sorta hear metal grindingt- almost like there is metal particles or rust on the threads.

Thanks in advance!

I'd say if there's a chance of rust inside the gun you should take it completely apart. Get hold of a rebuild kit and that will give you all new o-rings to use.

You will definitely need to take the reg off the back of the valve. For one place, www.airgundesignsusa.com has rebuild kits which have all of the seals in them. It sounds like you will need them.

When you get into the regulator you will find a small white plastic washer on the regulator pin assembly. It is a split washer and is supposed to have that crack in it.

Grease (not oil) the spring pack with something to prevent rust. Only lube the adjuster threads enough to prevent corrosion and sticking. Neither one is really critical in the amount they get, as long as they won't corrode. Check the forum stickies for lots of other info.
