LPG Regulator / Vaporizer issue on an Onan Engine

mardi 2 février 2016

Ok, details first but I don't think the actual equipment specs are a factor for this one. Picked up a Simon Eagle 32/21 Mobile Aerial Lift a few weeks ago. It has an Onan Performer 24 twin cylinder engine. When I went to pick it up, it ran fine, cranking up on the propane with no issues (dual fuel unit but the gas feed was in bad shape and unusable) Fast forward 2 hours and went to unload it and would not crank for anything. Fed a little gas into the carb and it would run for a few seconds so not an engine issue per se. Propane tank over half full and cracking the connection confirmed it had fuel there. Ended up having to drag it off the transport vehicle.

Fast forward 3 weeks and I have finally got to work on it. First discovered the propane solenoid wasn't engaging so temporarily set up a jumper to make that work and confirmed it was opening (removed it from regulator and got gas when I engaged it) So that led me to the regulator / vaporizer. Fiddled with it and was not able to get gas out the outlet side for anything. Decided finally to pop the cover off and discovered a load of GREASE in it. See Photos. It is a Century Model G85 Converter (# 4012). The grease is pooled in what would be the bottom of the cavity when the unit is mounted.

I have worked on plenty of pneumatic regulators over the years but never any LPG reg's but my instinct tells me that this is not right. The mighty big question is, Where did that grease come from and why did it suddenly stop the unit from working after only a 2 hour trip up the road.

I am obviously going to rebuild the unit but surely don't want a repeat of this to occur. The LPG goes through a filter and the solenoid valve before hitting the regulator then direct to the adapter on top of the carburetor.

Any thoughts on where this grease came from would be much appreciated.
