Pre 83 Louisville
Hello I'm a beekeeper in the peoples republic of california.
I'm looking at purchasing an old tandem axle Louisville from a farm a few hours away. I would like to know more about it before i go as currently all i know its its a gas engine.
I haven't been able to get the vin but the farmer sent me a pic of a plate on the door and some other info
the plate reads
s80fvk93342
222 8802 118 Z ADN
390(u2) 199 38dO 711877
my eyes can't fully decipher the part within the ()
I will attach pictures that i have.

Welcome to FTE!
S80 = LNT800 gas (Tandem axle LN)
F = 391 4V FT gas V8
V = Kentucky Truck Plant
K93342 = 1971 numerical series, January 1971 production
222 = 222 inch wheelbase
No paint code, probably part of the special order. Looks like a repaint as well.
S802 = LNT800 gas, 39,000 lbs GVWR
118
11 = Medium Gray Metallic Vinyl OR Light Gray Vinyl
8 = Standard Cab without butterfly hood.
Z = Transmatic, Ford's name for the Allison MT-40 six speed direct automatic transmission with torque converter lockup
ADN
AD = Eaton model 30DPC tandem axles, 6.43 ratio, at least 30,000 lbs capacity,
N = Ford-Rockwell (Timken) Front axle, 9,000 lbs capacity with power steering.
39000 = 39,000 lbs GVWR
199 3800 = 199 certified net HP @ 3800 RPM
711877
71 = Los Angeles District Sales Office
1877 = Special Order Number
Is it a runner? Looks like hydraulic brakes. EDIT see post 4.
The FT engines are fairly easy to get parts for, unlike the Super Duty engines.
The Allison trans seems to be in circulation.
Brake parts, except drums, are available.
39,000 lbs is CDL territory
California ag exemptions:
Good luck!

That’s a air brake truck
I see the air pressure gauge along with air controls for parking brakes, power divider, wipers and front brake disconnect
Front brake disconnect is the worst and most dangerous thing ever installed on a truck
One needs to determine if the truck is equipped with S cam brakes or the old style wedge brakes
Most any part including drums are available for S cam system but not so much for wedge brakes
A photo of the brake components on the backing plate behind the wheels will help id the brakes it has

I was confused by what appears to be a "regular" hydraulic brake pedal and those switches.
Those are the kind of switchs used for the front brake disconnect, possibly parking brake, and the power divider. As I understand it, the differential in the divider can be locked for low traction situations.
Is it possible it's air over hydraulic?

Front brake disconnect, it disconnects the brakes on the steer axle which is about 50-60% of your stopping power when the truck is empty, if you have an accident with the front brakes disconnected their lawyers will love you.
If you can read the tag it should say wet roads on one side and dry on the other, flip the lever to dry and never move it again
It could say normal and emergency, if so put it over to emergency

]how hard can I safely work this motor? is there an upper rpm limit i shouldn't exceed if longevity of the truck is my goal?
are there any more modern engines that could be used as a re power if I need a replacement in the future?[/color]
If hauling bees i would be working at night when cooler, if hauling feed also probably bee doing so at night as that would be when i had the time.
eventually i would like to set up a pup trailer behind a tandem axle for night time bee hauls at 80k#'s of about 200 miles over the sierras but i gather that this truck may not be the one for that job

Brake parts, except drums, are available. if i had to source drums from a scrap yard would there be certain years/ model spec to look for?

On those models the brake pedals looked the same but air brake pedal was closer to the floor
the early models used a flip switch for the parking brake instead of the common push/ pull button one normally sees
A friend owns a 71 LT800 that I put many miles on, I removed the bed and mounted a 5th wheel for it to be used as a yard truck moving trailers around
This is why I recognized the dash layout, the flip lever with the rounded **** is the parking brake control, the other controls have twisted flat levers, that made it recognizable in the dark by feel
Power divider locks the front and back differentials together, kinda like 4x4 in a pickup, keep in mind the differentials are still open carriers so you may only have one front and one back wheel spinning but it helped
I’ve never seen air over hydraulic brakes on those trucks

Back in the day, many OTR trucks came from the factory without steering axle brakes. I owned a 1972 Brockway (same cab as a Mack) without steering axle brakes. Just the hub mounted to the axle with no brake components at all.

391 is factory governed at 3900 rpm, for long engine life it’s best to keep it at 3600 or less
I drove a 71 LT800 391 with 5x4 manual transmissions, I can tell you that grossing 50k lbs the truck was terrible slow on grades, no way I would have wanted a tag along trailer behind it
With that automatic trans that one will be worse
There is no easy engine swap from a FT style engine to another like the 429 or larger 477/534’s
You wouldn’t want to supply gas for the larger 477/534 engines anyway
To do what you mentioned a diesel powered truck would be a better option, but to my understanding Cali has pretty much outlawed ownership of any diesel large trucks older than 2010 models
Emissions!! Don’t you just love them

It’s sad but unlikely that todays certified diesel mechanics know how to change the points or adjust to carb on that truck

A new California Air Resources Board rule, which went into effect on Jan. 1, prohibits large trucks and buses made before 2010 from operating in the state.
The rule applies to diesel vehicles that weigh at least 14,000 pounds. At the close of the year, CARB estimated that around 70,000 big rigs, or roughly 10% of the state’s commercial trucks, were not in compliance with the rule............
However, as the final requirements of the rule go into effect, farmers and trucking company owners say it imposes a heavy burden, especially for small trucking businesses and agricultural producers using older trucks on a seasonal or part-time basis.........
Permission for use is granted. However, credit must be made to the California Farm Bureau Federation
