my kubota rebuild

[GPintheMitten]

Did you fill the tank?

Fuel shutoff open?

 

[mattbatson]

thx for all the suggestions.

the tank is full
I did not replace the fuel lines, but did replace the fuel filter.
the fuel shutoff is open

I might pull the fuel lines to make sure they are clear.

I actually tried starting it last night, and it would run 3 seconds then stop.

on the third try, it would just click at the solenoid. I thought maybe the battery was running down, so put it on charge, but still just a click at the solenoid.

I'll update soon

I would check the fuel lines to make sure something didn't clog them while the tractor was sitting.

absolutely, I will
and then will bleed the lines.

however, I cannot do that until I can figure out why it will not crank anymore.

I think it is electrical...there are so many questionable wiring splices

I looked over the wiring diagram last night and found a couple of things.

One, the fuse holder is supposed to have two 15A fuses, but instead it had two 25A fuses !
Geezus...
so, I will pull the two new 25'ers that I put in and replace with 15'ers.

Secondly, the voltage regulator has a wire that bypasses the plug. They then stripped some insulation off the wire it goes to after the plug and simply wrapped the end of the wire around the other one and taped it up.
Good grief.
so, I'm going to fix that also


the pic above is the wire that they used to bypass the R wire that comes from the regulator (described as "main switch" in manual) to the RB (red/black) wire after the plug.
From the diagram, this is the correct wire to splice to...they just did a crappy job of it. Don't know why they had to bypass the plug.

with regards to the RY (red/yellow) wire that is not connected to anything ...pic below...


that wire feeds a crapload of stuff...or should I say that it branches off to a bunch of different things on the panel of the tractor.
I suspect it is the reason the gauges (fuel/hour meter, etc)are not working...cause RY feeds into all of those on the panel.

I was getting close to figuring out where it went when my 4 yr old started to complain so I had to break off to deal with him.

more later...

thx for the replies BTW

Just a FYI....Kubota, as with others, makes one wire loom for a few different models. I have found that not all plugs/connectors are required to be connected to something.

Thanks for keeping us posted - I really enjoy keeping up with your work as it progresses.

Excellent point. I've spent a fair amount of time trying to figure out things that didn't need to be figured out.

I drove it today for the first time in years....

I have been having the issue where the starter solenoid just clicks when turning the key.
Well, I bought some tap splices so that I could fix the wiring at that one spot under the dash, and I went into the garage to start work...when on a whim I turned the ignition key

well, it turned over.

color me surprised.

So I started it though, it will catch and turn over.
So, I'm thinking there is a bad wire/too much resistance somewhere...I plan to go through all the wiring and connections and see what I can find.

however, here is a short vid of it running...


and here is a pic of it pulled out of the garage under it's own power so that I could clean up under it from over 2 yrs of accumulated dirt...
and give it a quick wash out in the driveway...


Still so much to do, that it will be a while before it is truly done...and I will continue to update

more later

That is a remarkable feeling when a project rolls under it's own power. Good job.
