 Topic: wd45, Oil smells like gas
Posted: 31 Mar 2011 at 6:49pm |
Hey guys.
Just got my first Allis.
My grandfather had them as I was a kid, and slowly the farm turned green.
Just got a WD45 to pull with.
When it runs, I can definitely smell gas.
Today, I checked the oil, and it looked a little thin, and when I smelled it.....yup, smells like gas.
Now, it's chilly here, and i have to play with the choke quite a bit, on the reverse side, to get her to idle correctly.
Do you think, while the tractor is warming up, the way the choke has to be played with, it is dumping too much gas, or would you lean towards other problems?
The tractor recently blew a head gasket, and a new one is on, but who knows what's inside.
Any thoughts/suggestions?
Thanks.

Sounds like over choking, running rich, or not running well enough to burn all the fuel. I would check the ignition to make sure it is running good. Adjust carb, does the engine come up to temp? If it is running cold all the time it can cause that. I think some cheap oils smell gassy when they get some miles on them.

I just got the tractor 6 days ago.
So I haven't run it long enough to get up to temperature.
What little I rode around the farm, the temp gauge never even raised a little.
Thank you for the input JM. My uncle knew how to adjust his (now mine for parts) WD, so I'll see if he can come by and teach me what to look for.

You may need to rebuild the carb. Made a huge difference on mine.

I would change the oil and then work it a little bit. Make sure it runs good and get her nice and hot. Might just be from sitting and never being allowed to run.

Thanks Glockhead SWMI.
The tractor has sat ALOT over the past few years, in someone's garage.
I'd love to hook a set of plows up, but everyone around here no-tils now.
I'll have to figure out someway to work her.

My service manuals tell me how much oil, and suggestions on what grade of oil to use in the WD45?
Thanks.

Replace your oil with a good quality oil, check your coolant level, keep an eye on it, it could be from the block internally sweating in the temperature change over a period of time in the garage, if you loose coolant, and your oil smells like gasoline or looks like it has white or brown foamy crap in it, it could be a head gasket at the worst. (hopefully not the case)...

If you smell fuel in the oil, I wouldn't run the Tractor till you get the oil dumped, and screw a new filter on it. If you have to run the Tractor on partial or almost full choke frequentely, you need to do a rotor rooter on the carburetor, and give it a good cleaning. Doesn't matter how recent it's been replaced. The only time you should need full choke on a good running and tuned AC engine is in the Winter and that's only to get a rich mix to initially get it fired up with the cold dense air with the old updraft system. Usually they'll run with the choke almost off once they light up. In the cold weather, once you get some cylinder head temperature built up, they should run without the choke. In the summer months, some finely tuned engines fire right up without aid of the choke. That's easier on plugs, rings, and cylinder walls... HTH

I have not used my wd45 in the winter, so I don't know about cold weather starts. In the summer, no choke required. No messing around. Starts right up, purrs like a kitten. I think Steve is on the right track. If the tractor sat for any period of time, all kinds of crud could get in the carb from the gas tank. Let us know how you do.

I'm having trouble figuring "where" the thermostat would go.
I see nothing that looks right.
I also can't find anything in my manuals.
Any suggestions?

The thermostat is located in the housing on the engine at the back of the top radiator hose.

OK, I just figured it out (I think).
I found a picture of what the thermostat housing should look like online.
I don't have one of them.
I took the hood off the old WD (part tractor), and that manifold that mounts to the top of the head, has thermostat housing built into that manifold.
My WD45 has nothing.
Anyone ever seen that?
This is probably why I have trouble building heat. Wth just an open system, it is constantly cooling. No thermostat to close the system, it can't build up heat.
Why would a tractor be that way?
Is that normal?
Should i take that manifold off my WD so that I can have a thermostat on my 45?

I'm not sure about WDs and WD45s, but the early Bs didn't have thermostats - temperature was maintained by opening or closing shutters on the radiator. The early JD A's didn't have thermostats either, and probably many other tractors designed to burn distillate. Somebody else should be able to chime in about your tractor.

hey J.W. Freck,
see my 2 photos under (suppose to be a thermostat? WD45).
My WD45 has a long manifold covering the 2 ports, but no thermostat or thermostat housing.
My old parts tractor, WD, has the same type of 2 port manifold, but it has a housing for the thermostat.
I can't figure out why my WD didn't have one.
