New Project, '66 4000 Gasser w/ a Hole in the Block

Hi everybody, new to the forum here, but have been reading for a little while. About a month ago I picked up new project, '66 4000, gas, 8 speed. I had been looking for a 4000 for a while but hadn't found much, wasn't looking to spend a fortune. This came up at an auction that a friend was attending, so I had him throw a bid on it, I knew it had thrown a rod. Ended up winning it right at my max bid, $1100... Tractor turned out to be a little bit rougher than anticipated from the pictures I saw, so maybe not the greatest deal, but at least it's something. Heck, I had too much free time anyways! :wink:


First thing I'm working on is tearing the engine down to see what all is useable. I think the hole in the block is not that big of a deal, we'll have to see what all else is bad. Finding a junkyard gas engine may be an option, but I'm hesitant to spend a ton of money on something that may need a complete overhaul anyways. If I can salvage the block, get the crank cut under, and put a few used/new parts into it that would be the most practical. I know some of the engine internals are the same between the diesel and gas engines, is there a list anywhere that breaks it down? Appreciate any advice!

(will see if I can get some pictures later today)
 
The 3 cylinder shares some of the same parts between the gas, and diesel. The major differences are the cylinder head, pistons, and the gas has a .200" shorter stroke crankshaft than diesel engine used in the 4000. Like the Perkins engines they took the base diesel engine, and converted it with a few different parts to run on gasoline.
 
You might want to look for a used engine. If you do, look for a 68 or later. The early ones were 192 CI while the later ones were 201 and had a bit more HP.

This is true, the cost of parts, and labor to fix the engine you have may come out close to, or more than the price of what you can find a good, used engine for.
 
$1100 isn't too far out of line for one of
those. Even with a hole in the block.
The deciding factor for me would be the
tires. If they are decent then you did ok
imo.
They are outstanding tractors.
Welding up a hole in the block isn't a big
deal but I would want to have it line bored
afterwards. Lot of forces in play when that
rod let loose. So price that into your
equation.If it came out on the cam side I
would consider the block to be junk.
If you do need a block - or engine, as said
below I would either look for one from a 68
or newer 4000 as they were all 201 ci = 4.4
bore X 4.4 stroke.
(Yours is a 192 ci = 4.4 bore X 4.2 stroke)
Also, all the 4000 diesels were 201s so you
could buy a used diesel short block and
rebuild that as a gasser.
Block, crank, bearings, rods, cam, lifters,
push rods and rocker assy, etc are identical
between gas and diesels.
Welcome to the Ford board by the way.
You might tell us where you are located.
A lot of us mess with these 3 hole Fords and
might have some of the parts you are looking
for. Not quite kosher to advertise here
(there are free classifieds here at YT) but
there is a bit of horse trading and
networking amongst the regulars here.
But shipping something like a block or even
a crank can quickly nix a deal if the
buyer/seller aren't reasonably close - thus
the question on your location.
Keep us updated. We do like these old Fords.
And post some photos of the thing.
We'll pick it apart and laugh at how you
squandered your hard-earned money of course.
But we'll do it in a friendly way and help
you get it back together.
 
I put in a hard today, finished off supper and am about to go to sleep. If I missed part of the original question, forgive me.

I had a 4 cylinder block with a longitudinal crack about 3 inches about half way up the block....freeze pop. I cleaned it up, roughed it up real good, and applied a generous application
of JB Weld. I don't know how long it lasted but I know of 10 years it held with no problems. Kids sold the boat to a 3rd party.
 

I paid twice that for one with a locked up engine but it had good rubber and I knew the history on the tractor. Engine had locked up from setting and was fixable, but I needed the tires, wheels and trans for a diesel 4000 I was working on.

I'd be very suspect of the crank, if it broke a rod the crank could be bent, if the rod cap broke or came off most likely the crank journal has serious damage. 3000 diesel 175 engine uses the same crank, 192 gas, 201 gas and diesel blocks interchange, early gas connecting rods are different and no longer serviced so you have to find a used one or replace all three.

192 engine uses a different crank, rods and front pulley from a 201 and I'm not sure about the flywheel balance.

I do have a rebuildable 192 gas short block but we're about 500 miles apart.
 
Thanks guys! Some very good points brought up, I didn't realize I had a 192 instead of a 201. Definitely going to have to factor that into things. Will keep you updated.

A buddy of mine is a ford guy, he's pretty much the one that convinced me a 4000 was what I needed. Hoping to find some property one day, but for now just wanted something for general use and eventually a loader. The 4000 was big enough to do some serious work but also not humongous. I love working on old vehicles and snowmobiles, so a tractor seemed like an obvious choice. :D


Here it is the day I got it. The back tires are decent enough, but they're not perfect. They are filled though. One front tire is getting a bit rough, but still holding air. Check out that awesome roof!! :shock:

Also, I'm located is western PA.
 
Interesting that they did it right. GM could have taken a clue before they went the other way and ran off a lot of loyal customers.
 
I tried to pull the oil pan off but there were a couple of bolts up at the front that couldn't be removed. Got fed up and cut the heads off with a cutoff wheel. Found a nice assortment of parts in there!

Fast forward to last week or so, pulled the tractor down to the house to begin ripping it apart. Whoever owned this thing before must have worked at a steel mill, all the bolts for the loader and the front end of the frame had the nuts welded on. :shock: That made for some fun times with the torch.

There's a newer alternator installed, (poorly aligned albeit) and the wiring is pretty botched. Radiator has been repaired before and looked a bit gnarly but it was holding coolant. Gas tank looks clean inside. The drag link end needs replaced.

Engine hoist was sinking into the gravel (ground should be frozen right now, thanks mother nature...) and I had to enlist another ford to drag it to the garage. It was then I realized my old engine stand was not up to the task of holding this beast, so had to run to harbor freight and buy a 2000 lb. one.

Might stop by the local tractor bone yard tomorrow to see what they have. Are the exhaust manifolds the same between the diesel and gas engines? Mine's rusted through pretty bad in a couple spots.
 

That's some serious damage.
Yes the exhaust manifolds are the same.
You at lease need a short block.
69 and later models not only changed from 192 ci to 201, they also had a improved head and cam for better air flow to help increase power along with having the stronger rods like used in diesels.
The extra 6-7 hp comes in handy at times.
 
Here's a few more pics of the carnage from the original engine.


The inspection port,

(I still think the hole alone wasn't a big deal :p)

Piston was broken up but it looks like it didn't hit the head too hard.

Crank journal pretty beat up,

Then to top things off, it turns out the cylinders were already bored .040" oversize. So I guess that pretty much writes off the block and crank. The next chapter begins when I went parts shopping at the local salvage yard, maybe I should start a whole other thread for that, haha.
