FORD 7700 Advice

I have acquired a 7700 with water in the oil. Its FREE! NOT!

With out a lot of detail, here are the facts. Was running when parked, old man got Alzheimer's, family let it sit 4+ years...
1. Rusty Exhaust... water is turbo, intake and into the head.
2. Crank case full of antifreeze. its on the Texas Coast, don't think its cold enough here is crack head or block, but machine work will tell.
3. Hyd Hoses probably need replaced, but that's a maintenance issue.
4. Fuel tank was drained.
5. injector lines have serface rust, but no seepage, seems still intact and sealed
Tires are still in great shape, look new, still hold air/fluid.

Name place numbers:
tractor number: c534980
model: (E oe F) c2150
Unit: 7c28b
Engine: 7b22b
Trans:7a27
Hyd Pump: 6m22b
Rear Axel: 2a28b
Hyd Lift: too damaged to read

Labor is free.
Is this worth the rebuild? I need it for Hay and property clean up.
I cant determine which turbo is on this, but it has switzer on it, possibly 2 types, 1 is 350.00, the other is 1100.00...
Has front end loader and hay spear.

Any advice is appreciated...
 

EC2 is for a 6700
FC2 is for a 7700
Should be FC215? no listing for a O
FC2= 7700 flat deck 1976-1980
1= diesel engine
5= 540/1000 pto
Last number or letter is the trans code, C would be the standard 8x2 trans, but I have no listing for a 8x2 with dual power.
If that tractor has a 8x2 trans with dual power I'll add the 0 to my list.

7C28B is the build date
7= 1977 for this model
C= March
28= the day
B= day shift
This tractor was built March 28 1977 on day shaft

Serial # is correct for a tractor built in 77

The engine is a 256 ci turbo diesel.
They used Schweitzer turbos until 1978 when the switched to Airereach turbo, that one has a Schweitzer.

Water in the turbo and head sounds like it's had a lot of water down the exhaust pipe, being in coastal Texas has it been under water?
As long as the blocks not cracked it's sleeveable, but it's hard to say what it'll take to fix it until it comes apart.

Probably not worth fixing!
Texas coast is 1000-1500 miles from me but sent me your address , I'll drive my truck and trailer down and haul it off for you.
:wink:

As far as I know, all 8 speeds were a C code at the end of the model number whether they had dual power or not. There's nothing that I am aware of in the model number to indicate whether or not it has dual power.

new round of questions....
Its a little confusing on weather its a "Sleeved" style Cylinder. I saw something stating its not. but now I cant find that comment. I am in information overload.

Are there any free or online parts breakdowns for this engine.

THo I can build race car engines "old School" fast.... I know ZIP on tractors... I understand In frame builds, what's different in the parts packages for in frame, the Rear seal?

With out a crystal ball, think I will have any camshaft issues?

"interesting oil in this here ford..."
 

It is not a sleeved engine but it can be bored for oversize sleeves to put the block back to standard size bore.

With the amount of water it's been subjected to the engine will have to come off.
256 turbo engine has different rods and pistons from non turbo engines, rod bearings are also different.
Standard engine has 1 1/2" dia wrist pins.
Turbo engine has 1 5/8" dia wrist pins.
Turbo pistons have tapered keystone style top ring.
Rod bearings have a hole in the center to sent oil up thru the rod to lube the wrist pin and help cool the pistons.

When gooding for rebuild kits make sure their for a turbo'd engine.
Other than looking up prices don't order any parts until the machine shop says what the final bore and crank dimensions will be.

Looks like a Allied loader from the way it mounts, I have a 495 on a 6610.
 
`

keep in mind that a huge hurricane went through the rockport/corpus area a couple years ago... Lots of sideways rain. Dont know if its from that area.
 
For parts list, just google 'New Holland online parts' then put 7700 in the search and you'll have access to all the parts diagrams for that tractor. No need to sign in. If you google 'Messicks New Holland parts' I think they have parts pricing as well on their site.
 
(quoted from post at 10:57:36 02/26/19) I have a 1979 7700 with dual power and the model # is FC215M, trans code 9H10B.

Found a interesting change in the wording on my list
65-75 series tractors
M= 16x4 dual power trans
75-newer tractors
M= 16x4 manual trans
Apparently they left out the dual power part.
I'll make a note on my list
Thanks for the info.

I am not around the place where the property is that has the tractor. Can you explain the decoding of its a 256 vs 268? I am not disputing you, I just have not found that secret decoder ring...
I am working on getting a tractor to Victoria that has a wench that can pull it on a trailer and get it to the shop where my son works.
I agree its a total pull and rebuild, most parts say in tractor rebuild kits....
I am actually looking forward to this rebuild...
any words of wisdom on this style of rebuild?

Thanks again for the info.
 
I agree with this t, but it is on high ground, and house did not get any water either. This beast only got its feet wet....

256 turbo was the standard engine for the 7600/7700 tractors
They used the 268 turbo in the 81 year model only Blue Power Special.
268 turbo became the standard engine in the 7610/7710.
Many of the aftermarket parts suppliers give a generic listing of tractors their parts will fit, since the 268 engine was available for the 81 model they list it for the tractor without stating it was for one year only.

Some of the basic info on these tractors can be found in Tractordata.com
For the list that decodes model info and build dates some of the Ford guru's on this site have obtained or compiled a very good list of model codes and dates from the 8N to the 30 series.
I've been lucky enough to get copies of those list.
 
I am having a hard time finding turbo for this motor.
Any help would be appreciated. I see some for 350 to 1200.

Anyone have an outlet for these?
 

Alexanders used tractor parts in Texas is good of the biggest Ford tractor salvage yards in the country.
If they don't have the Schweitzer they may have everything to upgrade it to the newer Airesearch turbo.

You could also check around for places that rebuild turbo's.
I send mine to a guy in northern Indiana, he's treated me good.
