4010 overhaul upgrades?

Hi I have a 63 4010 that developed a serious knock and is currently torn apart to receive an extensive overhaul kit. I've heard of 4010's that have had a 4020 upgrade overhaul is this just a set of larger sleeves and pistons to get to 404CI engine??? Not sure but just throwing it out there

A 4010 had a 4 1/8" bore for 380 cubes. I'm not sure when exactly they stopped making sleeves and Pistons of that size but virtually every 4010 that been overhauled has had 4020 sized 4 1/4 sleeves installed.
I overhauled my 4010 a year ago with a Advantage Platinum kit. It's supposed to be higher compression. Haven't checked the horsepower but it starts and runs really nice.

When I rebuilt my 4010 a few years back, I bought my rebuild directly from Deere....they gave me a good deal on it. But while there, I also replaced the cam shaft as the lobes were worn but that also required me to change the gear that drives the tach (if my memory serves me right). I also suggest that you buy an extra set of sleeve o-rings and then use them in the groove usually open for the weep holes. Later years/models did away with the weep hole so by putting in an o-ring you get an extra stop against antifreeze mixing with oil.

I would do the overhaul kit that Richard suggests, as it lights them up nicely. I would also plan to replace the cam and oil pump. The gear gets worn and effects the timing.

Thank you very much for the replies, I was also wondering was when upsizing the sleeves do I need to have the next size of nozzle up for my injectors or would the stock configuration be sufficient? I am sending them in to rebuilt and if not can I get any performance increases by making any changes to the injectors and sticking with the stock pump?

Your biggest HP gain will be the extra 24 CID from the bigger 4020 sleeves & pistons. The factory injectors are fine as long as they're clean and have a good spray pattern. You can gain HP with turning up the inj. pump. A good pump shop should be able to get you an extra 20-25 HP from just pump work which can cause the tractor to over-heat, maybe blow the head gasket, or cause rear end & transmission problems. Dad had a '63 4010-D with the 4020 kit in it, ran it three years, '69 to '71 and it was getting weaker and weaker, had an injection pump pro make a house call one night in '71. Tractor was down around 60-70 HP before the pump work, was making 100-105 afterwards. Engine popped the head gasket about 50-60 hours later, and most of those hours were a little disking & harrowing, cultivating 200 acres of corn/beans w/4-38" frt mount cultivator, then fall plowing about 20 acres before the gasket went. Engine was rebuilt that winter with M&W pistons, inj. pump set back to stock 4020 spec's. Year later the new owner added an M&W turbo, and within 6 months to a year tore up lots of expensive parts in the trans & final drives.

Did that inj pump pro bring a dynomometer with him to check those HP's or was that just a WAG.

No, a REAL Experienced SWAG. He'd rebuilt 4 pumps already that day. Their shop at the time was the largest Steiger tractor dealership in the US, did R&D work for M&W Gear, and sold DeKalb seed corn on the side. Dad grew up neighbors to the guy's Dad. The guy was their main mechanic.

He knew his way around a Roosa Master pump! He did have a dyno at his shop, and nothing left his shop until it ran the dyno for an hour. Which is why the self-proclaimed, "Best JD diesel mechanic in the Midwest" who tuned the 4010 in '69 didn't catch the fact that some IDIOT ground the ends off the leaf spring in the pump unequal amounts and the engine was running flat out on 3 alternating cylinders through the firing order, and the other three were loafing along at maybe half throttle... hense the 60-70 HP. The Best in the Midwest didn't check ANY of his work, charged through the nose for his precious dyno time, which he could make show about any HP he wanted.

When we field tested the 4010 after the pump rebuild, 7th gear with a 12 ft Kewanee disk in soybean stubble with the wheels up on the disk. Before the rebuild, 5th would have been a good load. The pump PRO was actually impressed.

One of his project tractors was an IH 706 w/Nuess D310 engine making 140 HP on the dyno. The only tractor he had in his shop that he didn't dyno was the Steiger Panther w/VT-903 Cummins engine they used at the local county fair tractor pull as the pull back tractor. After the last heaviest class, they'd hook that Steiger to the front of the sled and let him pull the sled a half mile around the horse track instead of only 300 feet. That engine was making WAY over the rated 320 HP.
