Select O Speed Model & Lube sending wire

801SOS

Member
I had an earlier post about no spark. I got it fixed and its running good now. My question is how to tell what model it is. The serial number was painted over so I cant see it other than 81. The emblem on the front has 800 and on the side panel it says 801. Not sure if I can assume that it is truly an 801? Also the lube sending wire was cut off by the transmission I would like to replace it. Any suggestions the light for it is missing as well. I did not see it listed as an available on this site.
Thanks!
 

Look behind the serial number for the 3 digit model, this will tell you which model you have, but the select o speed wasn't available until the 801 series was introduced so it can not be a 800 model.
With SOS trans it should be a 871 with since speed pto or 881 with two speed plus ground speed pto

The transmission wire for the light enters the hydraulic case in the traction disconnect lockout or where the pto lever would be on the 851/861. There is a pressure switch on the output of the SOS output that shorts to ground below 3 psi. The switch to ground is what causes the light to light. The switch can be R+R through the access cover, but open a new can of patience.
 
"The switch can be R+R through the access cover, but open a new can of patience."

You can say that again. a teenage dwarf contortionist with two thumbs on one hand would be useful.
 
Ok I guess I will hold off on the lube wire at this point then. And those numbers are painted over too. :-( And it does have the two speed pto plus ground. so that would make it an 881? One other question on the "dashboard" I have the oil gauge, temperature gauge, fuel gauge and proofmeter. and then an empty hole right under proofmeter, what is suppose to go there? When would I use the ground speed PTO?

Thanks!

That is correct.

When you're using an implement that calls for it, like some hay rakes.

To clean the air filter the manual says to use a cleaning solvent, what kind? And where can I find a instrument panel light? And any words of advice on replacing the transmission filter.
Sorry for all the questions.

Don't do it . . . unless you understand cover removal and replacement procedures to a T!

The mesh is steel wool and the housing is steel also, so you could use just about anything except acid. Most folks use kerosene or gasoline. Just make sure it's done in a well ventilated area with no risks of spark around. Soak it for a few hours at least, agitate/swish it around a few times during that period, and then let it drip & air dry. Or, if you have a parts cleaner you could use that with whatever grease cutting solvent you normally use in there.

We're not allowed to post links to competing sites here, but if you Google "Dennis Carpenter Ford Tractor Parts" you'll find a site that sells replacement instrument panel light assemblies for both 6 and 12 volt systems.

As Larry already said, don't attempt opening up the transmission to replace the filter unless you have the proper Service Manual and have read it thtough at least several times and become familiar with the procedure. That filter has a bypass so if it is clogged, which it probably is, it probably hasn't been in use for quite some time, and changing the fluid often and cleaning the inlet screen every time that you change the fluid should be all that is needed.

I do have the manual but since it aint broke I don't think I will mess with it. What type of fluid do you use for the transmission?
And thanks again for your help!
 
What type of fluid do you use for the transmission?

Universal Tractor/Trans Hydraulic fluid that says on the label that it meets or exceeds the Ford/New Holland M2C134D specification.

thanks again for your help and sorry with the problems with the prior post about no spark.

Whats the best way to test to make sure the generator is working properly
 
(quoted from post at 10:55:03 05/07/20) Whats the best way to test to make sure the generator is working properly

A good voltmeter with leads from negative to positive posts at the battery while the engine is running - and again while it's not - or vice versa.

okay everything's good to go put back together but now I can't get the transmission disengage to re-engage hiya disengaged it to tow it to my new place and normally it re-engage is really easily but now it's not any suggestions it is sitting uphill and I hooked it up to my truck to pull it Forward maybe was thinking that it was bound up but that didn't work
 
remove the lever, position a crescent wrench on the fork and tap gently with a hammer, remember, gently...and in the correct direction.

if that doesn't work, remove the side cover and use a pry bar to 'unstick' the coupling.

I am always careful to decouple the transmission gently and only so far as to clear the pinion shaft so the coupling does not slam to a stop against the machining of shaft.

Sorry I was using my phone and voice for the original message and didn't have my glasses on so it looked like it was ok not garbled. But I will give that a try and let you know.
