GAS-5 Gascolator, what's in these things?
I bought a GAS-5 Gascolator and thought I'd have a look see what's inside one.

I took the retainer plate off, 4 screws, and could not pull off the bowl, seems pretty fixed....

So, does anyone know what's in these, meaning IS there a filtration element of some kind? Ever replaceable?

My old C120 has a John Deere gascolator with a filter element that you can clean if needed. What's in the GAS-5? Why doesn't the bowl come off?

rotate the bowl and pull down
Per the Installation Drawing

Remove the four screws and retainer plate. Rotate bowl while pulling down.
Yes, there's a filter screen in there.

I'm here to tell you, that bowl is in there!

Does anyone have a picture of one apart?

The "O" ring is stuck-----try tapping the bowl with a soft faced mallet to break it loose. (The bowl is machined from a billet, stronger than it looks, so don't be afraid to apply a bit of force). Then turn/pull like previously mentioned.

The drawing linked above pretty accurate.

Watch out for the plumbing on this, only one inlet but two outlets. See this thread.

Just turn it while pulling, it will come out.

Mine came out hard also, but it will need to be inspected annually. Part of your problem might be that the base is not fixed. Mine was that it was in a hard place to access.
I has trouble getting the screen out, but thinking back I will have to look closely to see if it needs to be removed. Will the dirt (if we have any) be on the underside (visible without moving the screen)?

Thanks for the inputs, I'll eat my Wheaties and try disassembly again!

Shoot a little thin lubricant (I use silicone spray) around the bowl/base joint to facilitate the separation.

I have been using NAPA SilGlyde for many years for "O" rings.

One tube will last a lifetime.

DC-4 works well. Also, Parker O-Lube.
