Onan oil change ??

How have you been removing the old oil without a mess. The drain plug is on top of a solid steel plate and the oil would run all over the place if I just unscrew the plug. I would guess you use some kind of pump. What kind and where did you get it. Probably stupid simple but I don't want to experiment.

If I couldn't remove the metal plate easily I would cut a hole in it so the oil would be able to drain. I would probably cut a hole in it even if I could remove it to make it easier in the future.

Siphoning the oil out probably wouldn't get it all out and it would probably leave dirt and residue in the bottom of the pan.

Another option would be to install a Fumoto oil draining plug with the nipple for attaching a hose to it.

Depends what model Onan....but I know on the few I've had (3600 and 4000w gassers) there looks like a drain plug under the fill/check oil plug... unscrewing it would make a big mess in the pan under the motor. That's NOT the main drain. If you get on your back underneath, there's a plate that comes off with two bolts and under that is the drain. Maybe this helps....maybe yours is different.

I formed a trough out of a piece of sheet metal to drain the oil beyond the obstruction.

In the picture, It looks like there is already a black rubber hose on the drain bib. You do realize the drain is not the hex plug, but the little drain to the right of it?

I had one of this generators once. It's hard to do the service without making a mess. Extending the hose hanging down would help somewhat.

Mine is the same as Wayne's. There is a rubber hose that comes out of the petcock. Open it and the oil drains out the rubber hose.

I think you are removing the drain petcock completely which is not necessary. Look and you will see a rubber hose on the bottom of the valve. Open the valve and it will drain out through the hose. Removing the fill cap will allow it to drain faster. The hose is visible in the pic provided by RinkersRanch.

Mine doesn't have the rubber tube attached. Anyone know what size diameter it needs?

Thanks. I'll get a piece as the last oil change was a mess.

If anybody needs a pump, I've been using one of these for years in a boat diesel: WEST MARINE Manual Oil Changer at West Marine
