Motor swapping and transmission issues

mikewood869 · Jan 20, 2019

After getting the 4500 running, we know we'll be splitting the 4500 come spring (there is a foot of snow) because of the leak somewhere inside the tranny. Since that motor is from a 1965- 4000, could I just swap a tranny to a 8 speed with independent, pto and a rear axle or would this make the tractor too long or short for the frame for the loader and hoe? Another things is, since we have to split the 3000 (to fix a issue with the pto), would a 4000 motor fit on the 3000 8 speed tranny (3000 has live pto, know that; wiring, lines, tank and other things would have to be swapped) or would this be too much for the 8 speed tranny from the 3000? Back to the backhoe, would swapping the the motor from the 3000 to the backhoe, make it too under powered? If I was to buy a transmission from 4, 6, 8 speed ag transmission, could that replace the torque tranny (I'm guessing that the 8 speed tranny would have non live, but no pto)?

Lot of good questions.
I can answer a few.
Any 3 cyl engine will bolt up to any 3 cyl
tractor.
I ran a 201 gasser in my 3000 for a few
hears with no ill effects. It had a lot of
power. Ford built a tractor like that. The
2110 LCG tractors were built on the 3000
platform and used the bigger 4000 engines
with no ill effects. Of course the 3000
was single reduction rear end so if you
get to ram rodding it you'll likely blow
the rear end out of it. Also, the 3000
rear axles won't carry as much weight as
the 4000 axle will.
The 3000 rear center housing is shorter by
a couple of inches too so your hoe/loader
sub frame won't just bolt on without a lot
of mods.
Any transmission/rear end combo from a
4000 chassis is a direct swap with your
4500. I sold a 4400 trand/rear end to a
guy that put it in his 4500. Made a nice
package for him.
One word of advice: if you start swapping
transmissions on a Ford make SURE you get
the flywheel and clutch that came with
that transmission!

Would a four speed tranny work from a 3000 on the backhoe?

I'm pretty sure the 4000 and derivatives -
because of the double reduction rear end -
had a significantly higher output ratio
on their transmissions than the
3000/derivatives.
It would physically bolt up but would be
very slow.
Howsomever, the plain Jane 4 speeds were
known to be pretty fast.
Just picking numbers out of my ear here
but maybe you'd have a top speed of 8-10
mph instead of the usual 15 or so.
For a TLB that might be ok if you just
needed it around your property.
A 4 speed is the least desirable of all
the transmissions of that era so you might
be able to get one cheap. You would also
need to get the clutch pedal and linkage
and as stated, get the flywheel too.

Probably wouldn't be good for the FEL and backhoe then. I take it that a tranny from a 5000 wouldn't work?
