Hey folks.

I have begun the teardown on the Ford that I
bought as a non-runner.

It was a good thing that I decided to rebuild
the motor as it looks like one of the rod
bearings had just begun to spin.

I have not removed the camshaft as it has a gear
on the end that needs to come of and it is
obscured by a sheet metal cover that looks like
a big freeze plug.

I bought a service manual online that was
supposed to cover this model but has the 2
through 5000 ag tractors but not this one I
think. At this point I believe it to be the 201
c.i. motor.

I bought a set of carbide faced mics through 6
inches and have begun to try and get the feel
for them. I have been measuring with the mic
and also with a pair of digital calipers I have
and am coming within 2 thousands of being the
same.

Comments welcome,

Brad

Make sure you change that softplug [freeze plug] on the back of the block.. They will rust out and leak.. I've done clutches on Fords and the tractor developes an antifreeze leak soon after..

The terminology jargon differs from country to country,the rod bearings in the picture don't appear to have spun,spun means that the bearing shell has adhered itself to the shaft and turned around in the rod,that did not happen as the tangs on the shells are still intact,they have not spun,and have not picked up,there is some wear on them and they need replacing,the crank journals can't be seen in the picture but going by the bearings it would be my guess that's they are ok,what was the reason the engine would not run.

I am not completely sure. When I bought the
machine the head was off and I could not do a
compression check but I suspect low compression as
the cylinders are a bit wavy and scored.

The ford manual set is rather dissapointing, but it's what applies, depending what you got.

The motor stuff is almost all the same as the (3 cylinder) 4000 tractors, and that's where the manual set sends you - only difference is the 4500 has a structural oil pan, and there's a little tagalong section in part 25, chapter 5, about that (part 25 also has the 4500-specific radiator shell and power steering bits.)

This is diesel or gas? With diesel, one reason it might be head off and then sold would be if there was a coolant leak, and it wasn't the head gasket (perforation, cavitation, or whatever the correct term for pinholes into the cylinders that for some reason are more common with diesel engines and special diesel coolants/additives are sold to prevent.) I think if that happens you have to sleeve it, but that's well into the realm of "have read about, have not had and/or fixed myself."

I seem to remember some dispute between Ford and Perkins when those engines were built with the rotary type injection pump,Ford did not want the ag tractors to have the rotary pump as it was more difficult to bleed than an in-line, that must be nearly sixty years ago as it was used first in the Dexta the only difference between it in the Ford and Ferguson was the injector pump and the rocker cover,it was badged Perkins in the Ferguson and Ford in the Dexta,the Ford industrial version did have the rotary pump,the pistons in the picture look like diesel,I think that that engine has dry liners,the type that has to be machined when fitted,but check on that one as I'm not 100% sure.

I agree with AJ about the bearing. Which one was that? Number 1 being the front of the engine.
