Commercial Waste Oil Heaters / CB 1400 oil pressure adjustment screw
« on: November 16, 2018, 10:55:36 pm »
Hello,
New to the forum and have an issue with my 1990ish CB1400. Over the years I have maintained the heater. I have an issue with the oil pressure adjustment. I have noticed that the screw for it has had less and less adjustment and is lower than the air screw. It has gotten to the point now where there is no adjustment to get set the pressure at the 2 psi. The oil pressure from the pump is good and there is no restriction at the filter. I assume that the diaphragm in the oil pressure regulator needs replaced, but ran across this site and joined. Looks like lots of good info here.
Anyone have any thoughts on this.
Thanks
