SOURCE: How do you drain the

Hi pplmelita,

If you don't have a petcock to turn the fuel off below the tank, I would disconnect the line at the filter and drain the gas out that way.
If you're wanting completely drain all old gas out, drain as above and then run until dry.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

Handie Andie

My bobcat has an onan mtr it wont stay on only on the rabbit

Float level may be low or high. There may be dirt in the low speed circuit of carb. Ot may also be a defective needle and seat or even a sunken float. If you eun E10 or E20, you may have corrosion in the carb from sitting- Ethanol absorbs water from the atmosphere.

It may also be an issue of the fuel quality too. If the gas sat for any length of time, volatility is impoaired. Especially with oxygenated fuels.

Bobcat starter stays engaged

Trace the wire from the "st" on the ignition switch to the small post on the starter relay or solinoid. If you find another wire going off from there follow it to the diode. It is likely covered with insulating sleeve at one end of the wiring harness. It is about 3/8" in dia and 3/8 long.Please note the colored band at the end which denotes the cathode.It must be replaced with one going the same way..
Hope this helps, Robert

SHOP MANUALS For the Onan engine

if you have the Robin, Kohler or other engine, just go here:
Scroll down to the bobcat 225 welders and select the correct or closest to yours as you can. your serial number did not cross.

For servicing the engine itself, I can find the specs, but Onan is quite tight with their manuals and discontinue a great deal of them so parts would need to be aftermarket in many cases. You might find hardcopy on Ebay, but the basics of teardown and inspection are the same across most of the flat twins.

How do I remove and replace a fuel tank on a BobCat Miller 225 Welder Generator model no. 907209 or 907210

Which engine on your unit do you have?

There are 11 different 225 models there shoule be 2 letters in front of your model number I need those letters.

The 907209 is a 23 Hp Kohler engine unit and the 907210 is a 22 Hp Robin(Onan) unit.
Parts list

Looking at the slot in the side of the fuel tank it appears that the bottom pan has to be separated from the unit. That would involve unmounting anything with wires attached from the base and supporting them. Engine frame, transformer / reactor, side panels, end panels battery and lower brace. I don't see any other way. I would try working from the engine end.

In all seriousness
I would contact Millerweld here:
Mention your on a very remote worksite, have the replacement part in hand and would like to know if there was a service manaul or any techical assistance available for the tank change.

Even with my 40 years of experience this would be a task I would have to study up close and personal to sort out exactly what the sequence would be to change the tank. It appears to be a very major evolution that could go very wrong very quickly resulting in some major damage if you are not careful.
