Turbocharging a 4020

RustyBolts said:
Ok, that makes sense now. Back in the late 70's-early 80's dad had a 4010 he pulled that he ran a 3LM and 4320 manifolds on, and he says that the turbo barely fit under the hood there, and burned the paint off(!). With how the hood tapers, it would make sense that with the turbo being farther back with 4430 exhaust the hood would need bulged out.
Did you strip the hydraulics off your tractor, or leave them intact?

No everything was still fully functional

That's what ours was a 68' How about that special reverse not listed, you know the one in the 4th/7th side then all the way past the stop, always wondered why they didn't label it.

The reason it wasnt listed is it was to fast and way to dangerous. It will go as fast backwards in 7th as it will forward in 7th. Most of the time you cant get the shifter into 7th reverse unless the linkage is wore or you file the shifter housing down

As far as that reverse. On the 3020 that my dad had it would go into that reverse as long as I can remember, and I would guess it was probably around the 2000 hour mark. Tractor probably still reads less than 6000hr. To my knowledge it wasn't modified at all. Maybe the 3020 diesel were different than the 4020 diesels.
 
It worked on some and it didnt on others. We have all the 10 series and it only works on a few of them. We only have 1 20 series and its a 4020 powershift ans a 2510 which is actualy made while the 20 series were being made. It is a cross between a 3020 and a 2020 but is desinated a 2510 and it will go into that reverse

Yup. The 4520 has 7300 hrs on it, and will do it. As far as I know, the 1010 and 2010, won't do it because their transmission is entirely different than the 30-4010. The 10 series Waterloos had the extra notch from the factory, but when reports came in about accidents happening due to the high speed of 7R, Deere changed it when they introduced the 20 series. (in the transmission anyway) there's just as many reverse gears as there are high range forward gears (3R, 5R, 7R, and actually 8R). Just to prove a point to me when I was a lil schaffer, dad took the cowl off the 4010 we had, disconnected the one shift linkage and slipped the trans into 8R. He only slipped the clutch, just to make it move a foot or so, he never let it fully engage. Then he shut off the engine, and put it back to normal. He then explained to me why the 4020's and anything newer with a Synchro-Range only had 3R and 5R. Another safety/convenience change that happened during the 10-20 series changeover was moving the PTO lever from the left to the right side to avoid getting caught on it when getting off the tractor.

LOL, I think you just missed the posting, we have a 3020 and it has the 3rd reverse.
 
I always called it 1R, 2R, and 3R, pretty interesting that there is a 4R. I put lots of time on that tractor.

It seems like everybody does, and I'm the only ont that calls it 3R, 5R, and 7R. It's probably because that's the gear right above it in the shift pattern, and the same speed. Even Dad calls em 1,2, and 3R.

If you do a search on google for 3020 synchro mesh, I saw a site that had decals and it actually says

1

3 3

R


So I could see the 3R, 5R etc the R was under the rightmost 3.

When I was 10 I rode the fender a whole summer learning from my granddad and watching his every move (whole new meaning to raw a$$ from the fender) the next summer I did the same for about a month with me plowing the straight ways and him doing the corners till he refused and made me take the corners, then one day he said stop up here and I did, he jumped off and said, go and see ya later and off I went at 11.......sure miss that old guy, great person and role model.

I've got some memories like that myself. That may be one reason I like 2cylinder Deere tractors as much as I do.

My 4020's a Power Shift, but dad's 4520 is a synchro range. Once the Synchro Ranges get a little wear in the shift quadrant, it's real easy to slip em on down into 7R. 4010's actually had it, but 4020 and newer, technically no as it was deemed unsafe to cruise backward at 12 MPH :badidea: Howsumever, I'd be lying if I said I've never used it :evil
As far as I know though, a 4010 quadrant will swap right over to a later tractor, or you could get out your die grinder and hogg out the one notch.:Cheer:

I've heard some people say that all 4010/4020 had the higher gear reaverse but I've been on some that didn't. The shifter would go into the position where it was suppose to be but there was no gear there I guess. A lot of them that had that gear had one row cotton pickers mounted on them at one point in there life. I'd wouldve used it to if I'd worked with one that had it LOL
 
I love 2 cylinder JD's, our neighbor had a mint 730, love that old school stuff.

The high gear 4/7/reverse was good when backing up with a 3 point chisel but I can see the dangers, still don't know what made me try that, sick teen I'd guess or bored!

Another shot of the manifolds.
Gonna treat it to a new head gasket too, which I'm goin to order in tomorrow.

Had a couple setbacks, one more serious than the other.
1: The turbo has a T4 mounting foot, and manifold is T3. Luckily, the mounting foot on the charger is about 1/2" shorter than a TO4, so that situation will be remedied by a 1/2" thick T3 to T4 adapter (Anyone got one layin around they'd be willing to part with?).
2: The 4430 elbow is a bit too long and would be so far ahead I'd have to hack up the hood (something I'm NOT going to do if it can be avoided). I'm gonna try a 4320 elbow, which is shorter, so hopefully we'll be back on track soon.
There is good news though; the head gasket set came UPS yesterday.
More updates to come.
