Continental F140 swaps

Hi all,

My venerable Massey Harris 35 needs an engine rebuild. With prices well north of $4500 (without shipping), and no time or shop to do it myself, I'm looking for options. I know Continental F140's were used in every industrial application possible in their time, and I can get a good engine from a Clark C50 forklift for under $1000. However, several engine rebuilders have told me that the F140's used in forklifts, etc., aren't compatible with the one in my combine. Something about a different timing gear and no oil filler (??).

Can anyone confirm or deny, and offer suggestions how to get my little combine back in operation??

Thanks!
 
The engines were made to order in lots of different configurations.

To verify if the swap would work would take some serious eyes on comparison. Even then it's risky, there could be some unseen minor difference that would be a deal killer after many hours and dollars trying to make it work. Then there is the chance that it being a good engine could have a wide range of opinion!

If your engine is still running, not knocking, hasn't been run out of oil or overheated, your cheapest route is to do a ring, valve, and bearing job. It may not be perfect but likely will buy some time.

Find a local mechanic, maybe a retiree, that will be willing to take on the job.
 
I know this don't help much, but I bought a contenetial out of a waterpump at a junkyard and put it in my MH 101 junior. Even had some parts left over. Was easy swap. Old engine was a victim of old man winter.
 
What does 'not compatible' mean? If it means the F140 (or 124 or 162 which all use the F400 Continental block) won't bolt up to your MF35 combine bell housing/clutch assembly, then I guess it is deemed not compatible. A lot of Massey Harris tractors (eg 101 Junior, etc) used those engines and they had a driveshaft coming out the back end of the bell housing/clutch which was bolted on the back of the engine block. In turn, the driveshaft drove the transmission/differential through a sprocket coupling. A driveshaft itself could drive almost anything (within limits of course). What does your combine have starting at the back on the engine block as it sits right now?
 
All help is useful! Good to know at least some swaps are possible. Now to learn whether engines used in forklifts are different from those used in all the other applications, from water pumps to welders.

Thanks!
 
The rebuilder who said forklift engines won't work said that Clark forklift engines have an idler gear pin at the front of the engine, and no oil fill location. How did they add oil I wonder? My engine has a belt pulley coming off the bell housing/clutch. Pretty dead-nuts simple...
 
First off i don't know these engines at all but I can tell you what the parts book says.
3 different cam gears with 48 or 56 tooth count.
2 different crank gears with 24 or 28 tooth count.
2 different front timing covers.
I assume there is more. I would want to be certain bolt on accessories to front cover fit with correct tooth count on gears.
 
Thanks for the info, Steve. That's what I was trying to confirm. While I know the blocks and internal bits were common across the F1-- range, I wondered whether bell housing bolt patterns, cam timing, etc. differed between applications. Even if driving a couple of hours each way with a trailer and a good visual inspection confirm compatibility, who knows how well the engine actually runs. I've pulled the head to find a scored barrel, but nothing else obvious (though I've not pulled the pan to check main & crank bearings. Before expiring, the engine sounded fine, wasn't burning excessive oil, and had a new radiator installed. Wish I had the time, I'd do the ring/valve/bearing job myself.
 
That's definitely sounding like I'd need to do more than a casual visual inspection to know whether a Clark forklift engine is a direct swap for my combine's engine. I'm liking the idea of having my local old tractor guru do a quick rebuild, if he weren't taking months to get my JD 4010 back in operation.
 
So CM ..... a belt pulley on a shaft directly from the back of your engine and no bell housing or clutch involved? Must be a flywheel in there somewhere. Email me at the email address below and I will send you a photo of what the Continental engine from a Massey Harris 101 junior looks like with the clutch/bell housing and driveshaft still attached. I can see the Massey Harris 101 driveshaft being used and adapted to a belt pulley system similar to what you have now. Here is my email address .....

Some forklifts had a hydraulic pump driven off the timing gears and had a casting that might interfere with the tractor frame. Or not.
 
they used to use a bunch of those old Chrysler engines in those old MH combines with the engine setting down under everything in the dirt.
 
There's definitely a clutch and bell housing upstream of the drive pulley/sheave. See the attached photos, and thanks for your input.

Good point- then again so are combine engines. But at least combine/tractor engines tend to run at a steady throttle, unlike forklifts.
 
My MH 101 with Continental F162 (same physical block as the 140) has a steel adapter plate between the block and the bellhousing. That kinda tells me those F-model Continentals are mostly the same at the back, and just different adapter plates to fit the application. I had an eye on one out of a swather that was a direct replacement. steve
