Swapping out Farmall M engines?

I"ve got a 1949 Farmall M that needs some major engine work, knocking noise...sounds like a WWII tank moving across an open field..."clank-clank-clank". I"ve also been told it would run a professional mechanic around 3000.00 to fix. I have another Farmall M 1947 that runs fine but am thinking about parting it out. First question, could a person swap out the engines between the two and have no problems? Is the engine swapping a difficult endeavor that would require a mechanic or is it a matter of watching the sequence of removing bolts and hoses and being able to reverse the process back? The "clanking" noise is the result of LOW-LOW oil for some time and tractor use. Could the crank shaft be warped? Rods or rod bent? Piston warp? The mechanic talked about a highly probable end result of throwing a rod(s). Or is it a matter of getting an OVERHAUL kit for the M engine....and the knocking is gone? How would someone check...properly diagnose this engine problem? Hope someone out there has the answers. Thanks

Would it be easier to part out the one that knocks and keep the one that doesn"t? You could keep the best sheet metal, tires etc. on the one that doesn"t knock.

it's not that hard. i did it this summer with one. but look real close at both presure plates to see which one is the best. some may form cracks over time. and of course you'd want to put the best clutch in it too. all you gotta do is unhook the steering shaft. block up the tractor, unbolt the frame rails at the bell housing and roll the front end away. of course this will take a few days but make sure you have help, a good engine stand that will fit those engines, and your gonna want a real good engine hoist. don't forget the 2 botls back by the starter. just always be aware of where your toes are just in case.

So, what is wrong with the 47 that would warrant taking the good engine off and putting it on the other? Seems to me, you be money ahead to take whatever is on the 49 that makes it so special and put it on the 47.

You may have bad timing gears. I have an m that i thought sure it had a bad rod bearing or something it was the timing gears. I did put new bearings and rings in it but runs fine this has been 3 years now uses no oil. It would use a quart of oil a day but now run it all summer and never add oil. What is wrong with the good runing m? Maybe switch tires etc, would be way to go. Just rambling on. Have a great day.

The knocking suggests it's going to take more than a piston, sleeve and gasket set. When you start rebuilding crank shafts, you could quickly find the cost doubles.

Your other engine should be a simple bolt up. If your not a pro as you seem to suggest, practice by removing the junk engine first. That way if you break something, you'll learn how to do it without breaking the same item on the good engine. Like you, I'm not an engine man, and tend to farm those out to pros. I just had a quote of possible $2,300. on my Farmall 130 engine. It doesn't have any strange noises, just blow by, and it's power isn't really that bad. One thing I find with rebuilders they use what they quote and appologize for the overrun. Oh, for the good old days when a pro would tell you, "It wasn't as bad as I expected, it's only going to cost 70% of what I quoted."

Good insight. Another question...Would you switch out the entire engine,block and all, or would that drop the value of the tractor? Do block numbers match up with the tractor frame? Or should I swap out all the guts of the good engine into the other block? (49 engine having the KNOCK problem, the 47 engine runs fine.)

Think about it for a second: What's going to drop the value of the tractor more, a good-running '47 block, or a knocking '49? Easy answer...

Changing the engine out is not all that difficult, it just requires patience, diligence, a flat smooth shop floor, lots of blocking, and a quality engine hoist. Your biggest problem may be in getting the 8 bolts out of the front bolster.

Basically, you take the tractor apart back to the bell housing, one piece at a time. There's a video available showing the process of rebuilding a Farmall M engine starting and ending with the fully-assembled tractor.

What video has the process you mentioned? Is it of good quality, can see what the person is doing or is it tough to see...but better than never seeing it done?

Id love to have a nice shop floor like some of you guys out there.

thanks

Doing that swap should not effect the value either way. The easiest way to do it I think would be to split both tractors like you would for a clutch replacement, and then simply attach the GOOD back half to the GOOD front half, but you will need a good set of splitting stands to accomplish that task safely.

Great photo..."a thousand words".

You wouldn't happen to have the plans for those bracing units you have for the tractor would you?

I like the way they look and appear to function.
thanks

I split tractors using hardwood pallets, have used this system on everything from a Farmall SA to the back half of a modern day articulated.

In your case chalk the rear wheels, place a bottle jack under the clutch housing. If narrow front, remove the front wheels. Place a hardwood pallet under the engine and front bolster. Using 6"x6" blocking, block it from pallet to frame rails and bolster, then using tie-down rachet straps anchor the entire front end to the hardwood pallet. Jack a pallet jack in unison with bottle jack, unbolt the tractor at clutch housing, the roll the front end away with pallet jack.

I've had two or more tractors apart in my shop at one time, and one pallet jack does all. I have had a Farmall 560 on 5 separate pallets. Pallet no.1, engine and front end, no 2 torque tube, 3 rear end, no 4 and 5 each rear wheel in a standing position complete with cast center. I've seen some quite huge components taken off machines this way, key is good pallets, good blocking and high strength tie down straps. I have moved the entire rear end of an articulated Deere complete with wheels on a pallet. Problem in taking those apart, unless rear wheels are off the floor, drive shaft won't let it roll.

any way you might send a photo of this set up? Doesn't have to have tractor on it but would like to see image...."a thousand words" type of thing.

thanks.

I don't have any photos, haven't used it for splitting a tractor since 2001. I used this a lot going back over 35 years on my dairy farm.

I built them from scratch. They are fashioned after the stands that Owatonna Tool Corporation used to sell.
