Rebuilding a WGP Ram

When troubleshooting a nasty leak out of the 3-way, I disassembled my front block in order to go over all the seals in my pneumatics (the gun had sat unused for nearly a decade). In disassembling the ram, I noticed that the seals had all disintegrated. Little bits of them came out like little rubber crumbs. Are these seals still available? If so, what do I need and where do I find them? Thanks.

Figured it out. Now I just need to get my hands on that o-ring. Thanks.

paintballgateway DOT com has bunch of Autococker products and they have been my sole source for everything autococker. Check there for your Orings. Compulsive Paintball normally has a bunch of good stuff as well.

There's also a stem seal on the rear of the ram- it's easily removed and replaced.

I believe the oring on the piston/plunger is 010, I'd suggest using a urethane oring.

The rear seal isn't a standard oring. It has square corners, similar to what it used in Belsales rams. I have no idea where to get the seal or if it was a proprietary part. It might actually be a standard seal of some kind. The good news is they are usually reliable, so it won't need to be replaced unless the ram is leaking out the back.

We used to call them "parachute seals"- I suspect it's an off-the-shelf part from a Humphrey ram.

I've actually been doing a lot of research looking for that back ram seal, I can't seem to find anything small enough to fit in there and seal correctly. However if you have a lathe there's a simple solution !

Is that urethane flat seal actually a seal? Because from the way I understand a ram to work, it just looks like a bumper. That oring would do the sealing.

You cannot see the seal we are talking about in the picture. It's inside the back half of the ram that's still screwed together. However, you did make me realize something else; I think the ram is missing a rear bumper. There should be a urethane bumper on both sides of the piston, but his ram only has one on the front.

Have you tried the Belsales bumper? It probably wouldn't work considering the shaft of the .44 ram is thicker than the stock ram, but it might be worth a shot.

Yes there should be another bumper. Unless it is inside the ram body still.
