Is it just me or does it seem odd that AC never tried using the 516 in a tractor. I would love to see it in a 7080, mine. Keep us up to date with pictures. Sure would love to see her run.

What I have read, was told, that the 516 was expensive to manufacture, thereby making it to expensive to put in a tractor.

Why did they put it in a combine from 1979 thru 1987?

The 426 barely holds together at 210Hp. The 516 in the N7 is 270Hp, probably their only choice, if they wanted to stay in house.

I would have applied the same logic to using it in the tractors. Dad's HD11 uses the 516 at 120 or 130 flywheel HP.

What I don't understand is how a company can be so disjointed that the engine plant works against using its own engines by treating the West Allis plant like an outside customer. It's all the same company!

From my 12 years at the Harvey Engine plant I always felt just the opposite; that West Allis treated the Harvey plant as the red headed step child.

I'll believe that. My point is that it was all the same company. Tells me there were problems at the top in running the company.

I have an 8070 in our shop right now that did the same thing with the water pump going into the radiator. Hoping tomorrow I will be getting the radiator back with a new core in it. The guy was bringing it over so I could put a new water pump in it. Right before he pulled in our driveway she let go. It literally would have been in our shop a minute later. The nice thing is it's given me an opportunity to address some other issues he's been having with shifting and so on.

Got the adapter plate today! Looks awesome and fits both engine and trans great! Now to bolt it up.

Cool

Nothing much for new pics yet. I got the right length belts finally. This way the fan is the same height as the 426s. Then you can also see the new alternator and alternator pulley. Still need to get a belt for that.

Lol we'll see how this one goes first. I got the flywheel and frame rails at the machine shop now. Im going to use the factory 516 flywheel machined a little bit. Ill show you guys what i did when i get it back. Also i had found a factory tappet cover oil fill for the engine but it would hit the starter. So i did this...
Factory tappet cover with the 426s oil filler attached. Simple and easy.

Hoping to have the other parts back by the weekend, but we'll see.

Sorry for no update guys, was having troubles with my old machine shop. He pissed up the original 516 flywheel. So now im goin to be using the 426s flywheel with the combines torsional damper disc. The shop that fid the adapter plate will be machining the flywheel now.

Here is the adapter plate, rear seal and starter installed. Starter will be repainted! Lol

Ive been doing piddly little stuff waiting for the flywheel. Instead of using the dual small spin on fuel filters, im going to run the 8000 series big filter from the 426. Had to make a bracket so it would fit. Still need to bend up some new fuel lines though.

She is bolted in!! Now onto welding frame rails and making the rest fit together!

Interested in what appears to be the data plate mounted on the block by the starter motor location.

During the time I worked there (70's) that "large" plate was only used on the commercial product engines and not on any interworks "IE" engines produced for other AC plants. The larger plate (length) not only had the engine series, engine catalog number and S/N but, also the catalog numbers of all the option groups ordered at the time of build. If that engine came out of a combine produced during my time at the Harvey plant it would only have the smaller ID plate which was the same height but, only about 3" in length and only gave the engine series, catalog and S/N.

Could you post a picture of it?

Hey guys, got the flywheel back. Woulda had it done sooner but my original machine shop pissed up the 516s flywheel, so i had the 426s modified to work for the 516 from the shop that made the adapter plate. He did a awesome job!

The mods to the flywheel are, the back side crank pilot had to be cut back .25". The ring gear had to be moved .150" towards the bellhousing, same with the pilot bushing, because the crank standout is .150" less than the 426. Then instead of using a torque limiter, i went with the torque damper from the N7 and had the Powershift hub installed. Then a 1/2" spacer plate under it to bring it more towards the bellhousing/input shaft.

More to come later.

...So how many of the flywheel mods could have been avoided by using the original planned 516 wheel?? Had you planned to use the torque damper/power shift hub concept originally? Thanks for sharing...Dale

This is all thats on the engine data plate.

Sorry nothing else to update you on guys. Been making 2nd crop.

Been working on little stuff between making 2nd crop.
Didnt like the goofy righthand side dipstick.

Opposite side has two ports for different dipsticks. So i popped one plug out and tried the 426s dipstick, and it fit and worked great!

Also started welding up the frame rails. Not done yet.

Peterson, Your project is coming along. I've enjoyed watching. Thanks for sharing. I had to go back to your page one and review your flicker photo album to help me understand your goals. Heres a weblink to those photos.

So are you saying that the AC 7040 side panels will encompass all of your new longer engine side frames?

Then ultimately, you end up with your own version of AC's 8095 prototype?

Doing a little trimming of frame rail to fit.

She is slowly coming together.
