800 series backhoe

[Wesley Briant]

recently purchased this tractor and want to get manuals for it etc... I cannot find serial number to verify actual year and model. The cingle emblem on front say 800 so obviously that
would be the series beyond that I found a number
on the right side above oil pan "2 EAF 8015-J" and further back on the side of transmission "720 with NDA 70088" on one side
and "730 with NDA 40248" on the other side. The fellow I purchased it from said it was a late 60"s model but I am thinking it is older. I went to change the battery and found out it was hooked up with positive ground I reversed it and it started again but it may have been designed to be that way. I don"t want to screw something up if anyone can point me in the right direction of where I can identify this machine I would greatly appreciate it.

WB,

I would guess you are correct and the tractor is a little older than the owner thought. My 1960 971 is positive ground and yours certainly sounds like it is positive ground as well. There will be others along to let you know if you may have burned up some component or damaged the genny, not my area of speacialty. In the mean time, return it to postive ground though the damage may already be done. The model # should be just aft of the starter on a flat spot. Should include Serial# there as well.

So... without knowing anything about this tractor.. you took it upon yourself to CHANGE the way the battery was hooked up... WHY?

Get a manual before you wreck that machine..

Now.. back to ID'ing it.. so you can get a manual.. before you change something else that may or may not like being changed.

Put your left battery changer (hand) on the starter.. put your right battery changer (hand) on the tranny.. look between your battery changers (hands)

On the flat spot on the bellhousing will be a stamped number for model, and a stamped serial number.

If this was a gasser, it should be 6v positive ground.. diesel would be 12v/neg grnd.. but they were'nt out till a bit later.

Soundguy,
alright I suppose I shouldn't mention that it was a 12 volt that I tried to put back in. I did not run it but 10 minutes or so. hopefully I did not damage anything. Anywho you see why
I need a manual (I'm not exactly mechanically inclined) I did as you said and the numbers behind the starter up on the flat area are "820 & 131074" assuming these are the serial numbers?

 

[souNdguy]

820 is the model #

131074 is the SN.. Indicates it is a mid 57 model.

It came with the 172ci gasser.. and was a stripped down model... probably why it is a backhoe.. etc.

You have to be specific onthe electrics. Alternators, if it has an alternator.. are gound specific.. It takes about 800 nano seconds to burn out the electrics in an alternator if it is hooked up to the wrong polarity.

Find out what you have before fiddling with more wires.

An I&T manual and / or the ford shop manual plus a parts manual will be helpfull to you if you are working on it.

You made 2 mistakes. One minor and one major.

1) Minor was changing something before you knew what it was supposed to be.

2) Major was telling us that you did #1~!!

Aside from possibly messing up a diode, there should be no long term damage.

Get a manual (the ford manual available online from e-scam-bay or the paper version). I would probably say to get a new wire harnes. Not much to them and available lots of places (like this site!).

Don't be worried about posting - while harsh at times - we do want you to have a good running reliable and cheap to operate machine.

thanks Chris,
I located the #'s for the tractor now I need to find them for the attachments. I was instructed by some other posters to "not touch until I had a manual" lol so I had better secure some for the attachments as well.
