Century M5 regulator G705

toolz · Jan 20, 2013

This G705 I recently bought was on gas when I got it, had all the LP parts with it, and I switched it back. When I turn on the LP, it flows right through the regulator (Century M5). The filter was a mess inside, and the regulator may also be. Is this regulator rebuildable? Haven't taken it apart yet. Are parts available?

If the pressure just shoots through the regulator,the primary valve assembly is shot. The valve is right where the gas goes into the regulator. There are 2 screws holding the valve in. Remove the screws and the valve pulls right out. You can replace just that valve. See if your LP dealer can order one for you. Just tell him you need a primary valve assembly for the M5. Just reinstall the new one. It's not adjustable. Just make sure the primary lever is properly oriented when you put it in. You'll see what I mean when you put it in.

Dan- I took out the primary valve as well as the small diaphragm and the main diaphragm. Didn't really find any problems other than the primary valve being dirty. Cleaned things up a bit and reinstalled everything. It works fine now and the tractor runs great. Don't know what I did, but it worked! Thanks for the tips.
