What year model is my ford tractor
Serial number-B996350
Model number- CA2136
I was told this was 3910 series 2?
 
Model number- CA2136 - That is not a 3910 model number

CA2 - 3600 made between October 1976 and the end of 1981.
1 - diesel engine
3 - live PTO
6 - Not correct for a number to be in that position. That last character should be a letter. If it looks like a 6 then it is most likely a C which would be an 8 speed transmission.

Serial number-B996350 - The B at the beginning of the serial number says that it was made in the Basildon UK assembly plant. The European serial numbers aren't well documented anywhere so I can't tell you exactly which year it is from, but if the x600 series Basildon serial numbers followed the trend of the x000 series before them, the number itself, 996350, means that it was made to be sold domestically in the UK.

Did you find those numbers on the sticker under the hood? If so, post the Unit Number and we can tell you exactly when it was made.

If those numbers are stamped into the flat spot on the bell housing, then they are only for the tractor that transmission was attached to when it left the factory. It could be that it really is a 3910 that had a transmission failure at some point and they swapped in a transmission from a 3600. What does the grill look like?

Here is a 3600 grill. Note the grill is inset into the radiator shroud:

And here is what a 3910 grill looks like. Note the side of the grill wraps around the sides of the radiator shroud a bit (I couldn't find any good pictures of a 3910 grill so this picture is actually of a 4610, but the grill is the same as a 3910) At some point they switched the xx10 grills from white to black so it may be black if it is a later one but the design should still be the same:

There are a few other differences between the 3600 and 3910 as well but the grill style is the easiest way to tell them apart.

The 3600 has a 175 ci engine that puts out around 40 hp at the PTO and the 3910 has a 192 ci engine that puts out 2 or 3 hp more.

The 3600 has the single reduction rear axle with outboard dry brakes and the 3910 has the heavier duty double reduction rear axle with inboard wet brakes of the 4xxx series (4000/4600/4610).
 
Thanks for information trying to get correct wiring harnesses due to small fire burnt mine up.
Unit # 8F05B
 
clean everything on the starter boss and look at the numbers again, the "CA2" is a 3600 from 1976-1981
 
Unit Number 8F05B means it was assembled on June 5 1978 during the day shift. So the numbers are from the sticker under the hood? Then it's definitely a 3600 and not a 3910.

Well your pictures show a 3910 style grill.

Did you, in fact, get the model number, serial number and Unit number from the sticker under the hood? (I can't see a sticker in your picture that shows the hood up with the fire damage), or did you get the stamped numbers from the flat spot on the bell housing?
 
Numbers was taken from tag under hood. Only number I could make out for sure was Unit. ID number. Is it possible to re-wire this or will I need to by harness? Only can get from ford dealer.
 

Everything about it looks to be a 3910 Series II, grille, lift controls, planetary rear axle.
3910 unit number should start with CA4, not 2.
8F05B could be a build date of June 05, 1988 which is correct for Series II models.

NH is the only place to get a wiring harness for that model, if it burnt the wiring at the cluster you'll need a complete harness.
Cost around $275.

Ironically I'm fixing to bring a neighbors 3910 to my shop with a burnt harness, it didn't burn as bad as yours.

I m getting a quote of 1350 dollars for dent and rear harness
 
I don't know what extra electrics a 3910
had over a 3000 but a full conversion
kit for a 10-SI with bracket and the
harness is about half that.
He doesnt need the tach drive on the
alt.
If the 3910 alternator bracket would
accept a 10-si you could do it for about
$125.
 
My guess is that the hood was replaced with one from a 3600. Look on the flat spot on the bell housing just above and toward the rear of the tractor from the starter. The flat spot is just above the two large bolt hole that I have circled in your picture. The serial number, model number, and Unit number should be stamped into that flat spot. They may be obscured by multiple layers of paint, so you may need to sand off the paint to see them, or you could try a pencil rubbing on a piece of paper.

Can't help you with your model, but that's a
common problem with Fords, positive wire shorts
out on the hood and they burn up, wrap a hose or
something around the positive wire so that dosent
happen again. Had that happen to a 4600 years
ago.

Thanks for the advice that seems like a good idea
 
Don't know why posts from modern view don't show
up in classic view, but Sean said he couldent find a
good pic of the 3910 grill, as he said it is the same
as a 4610, which is what I have, here's a pic of a
3910, there's no differences in them.

If I understand the question correctly, the problem is battery cables to the starter?

OTR truck dealers have everything you need to replace your two wires and if routed properly, no reason to chafe (opinion based on BTDT). Just take your
old ones in and tell them to make you a pair of these.

While you're at it they sell Size 31, ⅜" stud post, 925 CCA batteries for like $75....just bought one first of the year.....stock them by the pallet load. Yes the
terminals are on either end with the 31 but when you have your cables made if you want to use that battery, just have them make one of the cables the
additional length to reach the terminal on the far end of the battery.
 

Group 31 battery puts the studs or post up against the hood and sometimes doesn't allow the hood to close.
Group 49 battery is shorter and is a better fit, I have a group 49 in my 6610 and one of the 4000's, the rest will get changed over as the present 4DLT's go bad.
