Hi Guys,
I have just picked up a 86 F150 4X4 and would like to restore or replace some parts. How do I find what I have as for : Tranny, Transfer case, Rear end etc. I know that the motor is a 351 Cleaveland (at least that is what I was told) The Vin is 1FTEF26N5GKA65766 Can anyone decode. Also can a manual be purchased for that spacific truck only.

Welcome to FTE!

First of all there are tags on each item you described - on the tranny it should be on the driver's side halfway down the housing, on the tcase it should be on the very back portion of the case, on the diff, it should be on the flange where the 3rd member bolts to the housing.

Get those tag codes and post them here and maybe we can help.

 

Ok, first you vin tells be two things.
1. Your Truck was make in the USA (first digit) and,
2. Your truck should have the 5.0L (302ci) EFI windsor engine.

A quick way to tell is to follow the upper radiator hose back to the engine. If it connects to a piece that bolts to the intake then it's a Windsor (302 or 351). If it's seperate from the intake then it's a Cleavland. To tell the difference between the 302 and 351 W, look at where the heads bolt to the engine (The heads are the parts that the intake and the exhaust bolt to). There will be a line. If that line is even with the top of the water pump (where it bolts to the block) then it's a 302. If there is about a 1" space then it's a 351. Also is the truck EFI or Carburated ( the intake will come up and turn over the passenger side valve cover if it's EFI)? It was EFI from the factory.

As for the rears, if there is a bolt-on inspection cover on the back rear then it's most likely an 8.8" rear. If it's smooth and the bolts are on the front of it, then it's a 9" rear. The front rear should be the Dana 44 TTB (Twin traction beam). It will be split in the center so that both sides work independantly. If it's solid like the back rear then someone switched it. Are the axles still 5 lug?

The Transfer case is probably the chain drive Borg Warner 1356. It will be aluminum and have ribs cast into it.

As for the transmission, is it a manual or an auto? How many gears?

 

Also, www.helminc.com list a service manual specific to the 86 F150. It's $18. They also have wiring diagrams, and they are very detailed (I have a set for an 83.)

I would first look at a haynes or a chiltons manual for the truck. You can get them at Pep-boys, autozone...

 

Thanks f100beatertruck,

Sorry tried to add this to last thanks but screwed up.

Anyway what I was trying to tell you was that the motor was changed a few years back to a 1995 351 Cleveland EFI. I don't know if it is or not but the top rad hose bolts to the block not the intake and the line that u refer to ????
The tranny is a 4 speed standard and the clutch housing is bolted to the tranny.
The transfer case tag says New Process Gear 208f
The rear end is 12 bolt with a c clip to hold axle shaft in, it is not bolted at the hub. the crown gear says ford 39 and it does have 39 teeth as for the pinion gear it looks like only 10 teeth but I could be wrong as it is hard to tell without removeing it.
That's about all I can tell you now so any insite would be appreciated. ADMIN NOTE: No email addresses in posts. Use the contact form in the profiles.

 

The NP208 is a good transfer case.

As for the trans, as long as its an iron case, then it's probably a good one. There were T18's T19's and NP435's. Look on the drivers side of the case; I know the T18's are stamped "T-18" there.

As for the rear, the two common ones are the 8.8 (10 bolt inspection cover) and the 9" (drop out center). I don't think you have either one. Is it a 5 lug or an 8 lug rear? Could be a dana 44 or 60 rear.

Now to the engine. Ford didn't make a 351C in '95. They never made an EFI 351C to my knoledge and they didn't use the C in trucks. They did use it's kissing cousin the M or modified engine, but that stopped around 83. Count the valve cover bolts. 5 is the "FE" engine series, 6 is the "W" series, 7 is the "385" series (429/460) and 8 is the "C/M" series.

 

they did use the c engine in trucks just not in this country...

The NP 435 tranny will have NP satmped in the transmission by the bellhousing on passenger side or at least that is how mine is...

 

Thanks f100beater and 74f250

You guys know your stuff
We are getting closer to figuring out just what I have.

Transfer Case – identified = NP208

Engine – getting there, First it is EFI for sure, Also the upper rad hose connects to the lower intake manifold, and there are 6 bolts on each of the valve covers. My guess is it is probably a 351 Windsor but that’s just a guess.

Rear diff—close, Probably 39 x 11 = 429. It has 12 bolts on the rear cover. It is not bolted at the wheel but has a C clip on the end of the axle shaft to hold it in place, the filler plug is located on the front left of the case just back of where driveshaft connects. There is no drain plug. There are 8 lug nuts on the wheels.

Transmission – leave for now will tackle later after I have another look at it.

 

My bet on the axle is the Ford 10.25 semi-floating light duty 3/4 ton axle. 39:11 = 3.55 gear ratio. Is the front still 5 lug?

To tell if it's a 302 or a 351 W look at the front of the engine, off to one side. Find the valve cover, that is bolted to the cylinder head. The head is bolted to the engine block. Where the head and the block meet, there will be a visable line. It's most likly coverd with grime and you'll have to clean it to see it. Look at where the waterpump bolts to the engine block, if the line is right there then it's a 302. If the line is about an inch up then it's a 351. The head is about 5" tall then you hit the valve cover.

I looked at my 86 F150 and it was all covered in grime so you may have to clean it off. The 351 is basically a bolt in for the 302 that was in the truck, but there are some minor differances.

 

1 - Made in USA
F - Ford
T - Truck
E - 6,000 - 7,000 lb brakes / GVWR
F - standard cab pickup
2 - 3/4 ton chassis
6 - 4WD
N - in 1986, this code should mean 5.0L/302ci engine
5 - check digit; meaningless
G - 1986
K - built at Kansas City, MO, plant
A65766 - serial number

Post the codes from the bottom line of the VIN sticker in the door jamb and we can tell you even more, like the interior color.

BTW
The '95 351 (5.8L) engine is the Windsor, which is the ONLY 351 to go EFI.

 

Thanks steve83 & f150

I will check for that line on the block and let u know.

The door sticker reads as follows:

TYPE: TRUCK
WT 6374

special codes: T0196, F0618, B63911

EXTERIOR PAINT COLORS.......... DSO

WB = 133
TYPE GVW = F261
Body = LK4
Trans = A
Axle = B9
Tape = \
Spring = 636

Your truck is an F250 light duty 3/4 ton, not an F150. The rear is a 10.25 with a 3.55 limited slip (axle code B9). The front rear is most likley a Dana 44.

 

THE CLEVELAND ENGINE HAS NOT BEEN MADE SINCE LIKE 74 OR SOMETHING AND HAS NEVER BEEN PRODUCED WITH EFI ALSO I DONT KNOW OF ANY AFTERMARKET SOURCE FOR AND EFI SETUP FOR IT.. 302 AND THE 351W ARE SIMILAR JUST THE 351W HAS A 1" TALLER DECK HEIGHT.. AND THE STROKE IS LONGER FROM THAT CREATING THE C.I. DIFFERENCE..

P.S. CONTRARY TO POPULAR BELIEF THE 302 IS NOT A WINDSOR ENGINE ONLY THE 351W IS PRODUCED IN WINDSOR.. THE 302 IS MADE IN CLEVELAND..

351M AND 400M ENGINES ARE MODIFIED CLEVELAND BLOCKS BUT ALMOST NOTHING IS INTERCHANGEABLE.

 

True, but since almost all the parts from the small block fit it, it's just been applied to the 302. The windsor is in a class of it's own and the small block familly is the 221, 255, 260, 289 and the 302.

As for the EFI clevland, you could TBI it with a Holley Projection unit or make your own with a single plane manifold...
