Pulling season is over so I thought I'd check out the head gasket and valve train. Kept hearing some ticking and odd noises. Pulled valve cover off, took head to head shop for full valve job and trueing. Head gasket looked OK, but had a crack in cylinder sleeve #1. Number 4 looked suspect. So..... Bit the bullet and tore it down for a full in frame rebuild. She's getting new valves, seats, gaskets, pistons, sleeves, rings, rod bearings. Sent injectors to an injector shop for rebuilding. Bought new CAT head bolts. Not what I really wanted to do, but planning on keeping the tractor, as it's a good puller. I have a shed, I really, really, really need a good little shop.

Fun times we just finshed up doing a in frame rebuild on a John Deere 4240 few months back. It had a head gasket failure at 6700 hrs on all original motor and we planned on keeping it so we decided to resleeve and rebuild it while we were that far into it based on age and hrs and really wasn’t that much more work once you had head off and tractor broke in half. It got injectors, injection pump checked as well.

they make stout pullers. That is a good looking series of tractor. I know,,, my buddy was like...you could just reoplace two cylinder sleeves....I was thinking, crap, if Im going to all that trouble, whats 4 more sleeves...and make it brand new.

We use it on the farm and since we sold a bigger tractor it gets most of the heavy lifting so we deceded to make it like new again and freshin it up. Now just starting to need a paint job but not horrible yet. Plus those 40 series have held there value like crazy if not gone up so you could easily get the money back. I remember when dad bought it 30 years ago at a auction and they sell for just as much if not more as back then today. The 4240 factory are not the highest hp being on the lower end of that frame size tractor but nice thing is they are built heavy and do not seem to self distruct by pushing the limits of that frame size like the 44’s were.
 
Welp. Honed the cylinder walls, and got the new sleeves installed. Hopefully get some pistons in tomorrow.... Kept the sleeves in the freezer, took one out a time and they damn near dropped right in. The next to last I carried two out the freezer at once. Just the time it took to drop other sleeve in, about had to drive the last one in. Amazing how it contracts and expands I. Just a short time. Lesson learned, quit being lazy. 20191120_191000.jpg
 
I like old red tractors, especially 1256's.

I am not a huge red fan based on a bad experience with a 986 years ago but pretty sure it was just a lemon but heard a 1206 running the other day with the turbo charger and it sounded really good lugging around the yard and was done up nice.
 
I like to have a 1066 to pull. damn that old iron is expensive. Or a little Allis WD or WD45

emp_21.jpg emp_12.jpg Welp had a little time and got my buddies over to help me get the head back on. $658 bucks for head work, new valves, magnafluxed, new valve guides and trued the head. $360.00 to clean and rework the injectors. It's coming back together.

Worth fixin these old gals so you dont have to deal with emissions crap
This one will just be in front of a pulling sled, but I do have all the draw bars and pto and everything else that it needs to make it a farming tractor again. It would be a little hot to farm with but he would have a lot of power.

Got her running Jan 1st. Had to turn back the timing a little bit from the previous setting. I assume that was becasue it was making less compression before the rebuild. I dunno. I was a bit worried when I fired it up the first time. Little adjustment, and she started running much better. Now to find someone good at adjusting valves. ugh.
 
@Sneakymedic Let us know where your gonna be pulling at when the schedule comes out for 2020. I'd love to come and see you pull that sled to full length ++++.

As much as I appreciate your enthusiasm.... Hahahahaha. But I can tell you when we pull. :)

I drove this weekend to Wooster Ohio to pick up some new tires for it. It's coming together.

So...update. Get er all buttoned back up....fires up quick.....and......a knock. So.....head comes back off and you can see where the no. 5 piston was lightly smacking the head. So, lets go back down under.
Drain all the oil back out, all the new antifreeze back out.... the cap on number 5 was loose, finger tight loose. I either missed tightening it up.....which I am 99.9% sure I hit every one when I rechecked torque, or the connecting rod didnt get seated well before torque....or the POS Harbor Fraught torque wrench was crap. Too many variables. So, ordered new bearings for the connecting rod, awaiting them in the mail, bought yet another head gasket.... Took the head to be checked at the head shop...didnt bend any valves of push rods. (whew). Borrowed a freinds Snap On torque wrench for the reassembly.

Took the new tires to my buddy in Roanoke to get them top cut for pulling this weekend. Hopefully I will get a good dry day this weekend to button it back up. Meanwhile, while I am awaiting the bearings from California, I am cleaning all mating surfaces so its go time when everything gets here.

Overall, I am not mad, its a learning experiance. There arent a lot of these mechanics around anymore that will work on the older stuff around here. That was an expensive mistake (new oil, antifreeze, head gasket, bearings) but in the end its cool that I got it all buttoned up. Just glad I didnt throw a rod through the block. Im really excited that it fires up so easy. So, that is good in itself.

Its like a coworker told me one time. “If you don’t make a mistake occasionally your not doing anything productive, its all in admitting it and how you learn from it and move on so that you do not make it again.” Glad to see it coming together but finding dry weather or a dry sled track might be a challenge unless its indoors.

Yeah, I could have sent it off to get fixed, but if I am gonna do this tractor stuff for awhile, i'm gonna have to get in there and do it myself. I figure by May we might have a dry track somewhere.... Actually, I plan on putting fertilizer on the pastures in about a month...that right there will dry it up faster than anything. Then when hay is on the ground, monsoon again.
 
So, after reinstalling the head twice, cause I'm an idiot, and miraculously getting the engine back together with nothing more than a shop manual, last night was go time. Pulled 6700 ,7200,7700. Got third in the first class, weighted too light in front, readjusted weight for track ( it was sticky) and got two 1sts in the next two classes. Last class I was 30 feet in front of the 2nd place guy. It's a monster. I was only at 3/4 throttle and was a bit scared to do more with 4" of fire coming out of the exhaust.

Now to take all the tin off, retorque head, and check all the bolts. FB_IMG_1592170442072.jpg
