A question, and a lesson learned

First the question, I have a 1955 Ford 850 I would like to know how to tell if you have a single plate clutch or a dual plate clutch, it has a 5 speed transmission, from what I"m reading from a copy of the original shop manual it could possibly have a dual clutch on it, thanks again for the help, and finally, as I"ve learned things I"ve actually been to help on a couple of questions that other people have posted.

I"m sharing the lesson learned because I don"t want someone to do the same thing and get hurt or their tractor damaged, I got lucky no harm, went out yesterday to start the tractor and repair 2 front flats, checked the oil and it was WAY over full checked it several times thought a moment and thought maybe just a fluke so I decided to crank it and CAUTIOUSLY watch it, oil immediately starts blowing every where instantly shut it down, checked the radiator 1st then trans fluid everything good there step back a moment scratch my head trying to figure this out, decide to check the gas tank, bone dry apparently the float stuck Sunday when I cranked it to run for a moment and I didn"t shut off tank valve and the gas ran into the carb and up through the intake, so folks, please remember to shut off your fuel valve under the tank, I drained over 3 gal. of oil and gas out of the oil pan.

The 850 would have a single clutch and the 860 would have the two stage clutch.

well.. you got a clean engine now.

i think I mighta changed the oil filter too.. but if you have run it since then.. no sense in doing it now.

as said.. *5* are single clutch.. *6* are dual clutch..

Thanks for your answers, and no I haven't ran it yet and I am going to change the oil filter also, when I drained the oil I let it drain for at least 30 minutes (came out like it was water, I wonder why haha), I haven't replaced the oil yet but I drained it immediately.

We had a customer bring in an NAA a few years ago and wanted us to rebuild the carb because it was leaking and replace the starter because it wouldn't spin the engine over. When we brought it in the shop there was so much gas in the base it was leaking out the dipstick tube. The starter was fine but the engine was seized tight from running it with the gas in the base. Be glad you didn't run it and I bet you won't forget to turn the gas off from now on.

Nope I will not.

here is your quote:

"so I decided to crank it and CAUTIOUSLY watch it, oil immediately starts blowing every where instantly shut it down"


so.. you DID run it.... that means there is gas in the top end and galleys ...journals and all...

My 8N did the same thing once, the tempature was about zero. I always thought that the carb float valve iced up.

It is possible, though unlikely, that someone has swapped the transmission for one from an 860 to give the tractor live PTO. That's the only way it would have a two-stage clutch. It is easy enough to tell if it has live PTO: Attach a PTO implement, then start out with the transmission and PTO both in gear. Push the clutch in just far enough so the tractor stops moving. If the PTO is still running, you have live PTO and therefore a dual clutch.

I always turn off the fuel when I park my tractor. I've lost a lot of gas over the years when I forgot to do so. Also most casual thieves, vandals and "borrowers" won't bother looking for the fuel shutoff if it won't start.

Your carb should have a drain at the bottom, filled with sintered bronze, to allow fuel to drain out if the float sticks. Someone must have plugged it.

If still factory, your clutch linkage rod should have a double pin position on the clevis where rod is attached to clutch fork rod. To get the benefit of live pto, you will have to change the pin position to the rearward hole and this brings the clutch pedal up higher and you can feel the transmission clutch action and pto clutch action.

Soundguy, you made the comment that there is gas in the gallows and other places what does that mean and what should I do about this if anything, I haven't ran it since that day.

Thanks for all your help I've learned a lot just following your replies to other post

oil galleyes. that's basically the oil passagesways in the block.

since it had gas in the pan.. when you cranked it up for those few seconds.. it did circulate gas thinned oil to some extent.

at this point.. not much you can do.

change the gas thined oil out for new oil. change the filter.
I'd runt he engine over with out the spark plugs in to run the oil pump and circulate some oil before any compression loading starts.

once you ran her over a few times.. then put plugs in and go to rowk.

residual gas will flash off pretty fast with heat.
