Engine Swap

Jrucker · Sep 27, 2019

I have a 1968 4000 diesel that the engine is wore out on. I have found a 1998 4630 Turbo tractor that is being parted out. The engine is good, with 3100hrs on it. Will the 4630 engine bolt up to my 4000. My 4000 has the 8X2 transmission. I know that I will have to modify the intake piping, which isn't a big deal. But I am not sure about the bell-housing and the front end bolting up. they appear to be the same bolt pattern.
Any help would be much appreciated!

Should bolt up just fine.

I was told once that the 4630 is metric while the older models are SAE. True or false?

I have never heard that before. Do you think there will be issues with the clutch?

What are they wanting for the 4630 engine?
Have you priced rebuilding yours
If you 4000 engine was built after 4/68 I'd rather have it than that 98 emissionized engine, the fuel system for that engine is costly to repair

The basic engine structure is unchanged in terms of hardware used. Any parts engineered later and adopted may be metric.

The fellar that has it is asking 1500.00 for it. He bought the tractor New and has owned it, it s whole life.
Yes we just built a 201 for a 4600, basically the same engine as mine last year. It had to be sleeved. After machine work and parts it cost right around 2200.00. That is not doing anything to the fuel system.

The engine will bolt on to your tractor but with the small amount of dealing with the later emissionized engines I wouldn't want one.
A neighbor had a leaky seal in his emissionized inj pump, it cost more to replace the front seal than I paid to have my Cav pump completely rebuilt.

Another thing to think about, that 4630 engine is a 192 ci turbo charged engine, none of your 4000's oil bath air cleaner piping will fit so you have to custom make the piping, also the exhaust pipe outlet is forward like a 4600 so you need a 4600 left side hood panel or cut a new hole in the 4000's hood.

IMO by the time you make all of the modifications to get the 4630 engine to work on a 4000 you'd be just has well off rebuilding the original 201.

1 last question: What happened to the 4630 that has him selling the engine off of the tractor.

It rolled over a hill and busted the front axle and mount. I would have bought everything to make it work from the 4630 donor tractor.
After some thought, I think I am going to just rebuild the original engine.
Thanks for your reply s, I appreciate it!

I probably have everything it takes to fix that 4630 but I had another use for the axle assembly and don't need another tractor that size.
Parted out a 3930 a few years ago, sold the trans, converted my 4000 over to the 3930 axle and hydrastat steering, will be installing the engine onto a 555 Farmtrac soon I get time to work on it again.

The fellar who has it has already began parting it out. He has sold a lot off from it already. I am gonna pass on it and fix my current engine.
It is listed on Craigslist Lexington. He really isn t asking terrible money for it. 1500.00 for the engine or 2500.00 for the whole tractor. It still has rearend, trans, hyd. Pump, and all of the sheet metal on the front, as well as the complete engine. He said you can still hear it run.

Wouldn't mind having the transmission, rear center housing and whatever is left of the steering components.

Where are you located?

I have a few Fords myself.
