Thank you so much from Scotland UK for such an informative video - I have a 4230 here also that one day, if I'm brave enough, will do what you guys did. Keep up the great work.
I started working for a Deere dealer same time 30 series came out. Sound Gard cab was light years ahead of the competition, some never did catch up. The engine were a little weak. The 40 series were a much better all round tractor. Will be nice tractor when you get it all done.
It would have been very cool to witness the 30 series come onto the market! The first new John Deere Grandpa sold as a Deere dealer was a 4430, and that same tractor is sitting in the shed today 👍
Seeing this rebuild may help me like a 4230 again. My cousin had one a long time ago, and I had a love/hate relationship with that tractor. I loved to hate it...lol.
Sure has a much better sound than before and it isn't smoking under load WIN WIN and more hp I'd say you hit it out of the park Probably would last forever now Keep up the good work
That turned out awesome!!!! You and your uncle do dam good work!! Great video!! Your grandfather sounds like a awesome guy!! I hope we get to meet him a little more. It’s obvious he’s a hard working on the go kinda fella!! But maybe you could get him to sit down sometime and give a brief history of his farm!! I’ve been thinking about your barn that burnt and how you guys were making out with it. Well take care and as always WORK SAFE 😎🇺🇸🇺🇸 and talk to ya next time bud 🙂
That's how we finished our rebuilds. Fire it up, make sure fluids stay contained. Straight to the dyno. Absolute minimum idle time. Not looking for a power number at that point. We just wanted full load, full boost for 20 minutes. Idle it down, let it cool off. Next morning head re-torque. Oil & filter change. Sheet metal back on. Then if we were looking for a power number we would make pump adjustments on the dyno again. We found engines we put through that break in process made the same power for more hours with less oil consumption, and less blow by.
we had a 4230 engine blew and we went to Iowa and got a 4430 motor from a burnt tractor and put in...smooth running lots of power...the engine blew cause we ran alcohol in it..pulling ..broke the crank..didn't know what we were doing
Extra horsepower in a given size tractor is always ok until you overload the PTO or drivetrain. As a mechanic, I’ve seen the results of 150hp 4020’s and 806’s. Same size tools a gear faster and a little less throttle=fine. Add extra weight, bigger tires and pull bigger equipment=scattered drivetrains. No matter the brand.
What "settings" do you change on the dyno for a 4230 vs a 5020? We had a 4230 that started popping out of gear going downhill with a load behind. Traded up to a 4240 and never looked back!
In your words the 11000 hour engine turned 115. And the fresh engine with turbo and high compression pistons only turned 125. Any chance the dyno wasn't dailed in right for the first test? I am enjoying your channel. Not trying to stir shit. That first dyno test number just seemed high.
Lol at the fuel turned up comment .. it’s perfectly legal to turn the fuel up on a tractor or diesel truck no one is gonna get you for putting stuff about it on RU-vid
