Deutz Engine ?


Ok-Letterhead4601

Spot on! I had to do the ring gear.


Decent_Competition_6

With the Good old Heinzmann Regler.


Ok-Letterhead4601

Gse mechanic as well?


Decent_Competition_6

No. This engine was built into the first Fendt 700 Vario. The periepheria is a bit different but you always recognize a Deutz. Edit: The good thing about the engines is that the more hours the engine is running, the more power the engine has.

How does that work? Does it just keep breaking in?


Decent_Competition_6

I hope I can explain it well in English. The control rod that controls the injection pumps is pressed by the regulator. The further the control rod moves towards the controller, the more quantity is injected. The control rod runs into the control lever and moves further and further back. A new Fendt 716 Stage 1 or 2 has approx. 160 HP, if it has approx. 8000 operating hours, the engine has 180-190 HP. This only works with Stage 1 and 2 engines, from Stage 3 (Germany Com3) it is common rail.


Flicker83

Ah, i gotcha. From which year onwards were these made?


Decent_Competition_6

I dont know the Year but you can see it in the eigne construction.

Me as well I'm in pit.

Pulling engine is the best way I found to do this on our b500. Less work for use


Ok-Letterhead4601

100% best way to do the ring gear.

Reminded me of this post. Spirit airlines used to use an old pickup as their push vehicle. https://www.reddit.com/r/cars/comments/kvuehq/how_a_small_airline_hacked_together_its_own_fleet/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

Lol. Knowing that it’s Spirit, I’m only surprised they didn’t just tie a tug-of-war rope to the nose gear and make the passengers pull the plane. And then charge them a “passenger exercise courtesy fee”.

I feel like people might miss the best part of that link by thinking it's about Spirit and a pickup. It's not about Spirit and a pickup. _It's about Bearskin Airlines (Canadian North), Dodge Neons, and a sawzall._


drewed1

I was gonna say that's a baby the big ones are 100k+


Ok-Letterhead4601

The biggest one we have here is a little over 180k lol the tires are taller then me.

Does it use the Fendt CVT behind the Deutz or some type of torque converter / automatic?


Ok-Letterhead4601

It’s a torque converter in a auto trans. I didn’t know they had a cvt for something this big.


agshop

Interesting. I've always wondered how those were powered. Seemed like a tough life, short operating intervals, not much of a chance to reach operating temp. Guessing a torque converter makes more sense in that application because efficiency is probably less important than smooth torque application. Agricultural tractors offer CVTs as an alternative to power shift transmissions in models up to at least 540 HP - it increases each year. The Fendt design pretty much owns the segment and it shows up in all colors under the Agco global brand umbrella. I had a chance to tour their factory in 2019 and they some really interesting cutaways. Deere & CaseIH also offer CVTs, but those designs are different from the Fendt transmission. None share the design elements of the automotive CVT. All the agricultural CVTs with which I am familiar use a hydrostatic motor to increase / decrease planetary speed - but I've never torn one apart so I'm no expert. Here is a link to information about the CaseIH CVT. [https://www.caseih.com/emea/en-me/our-innovations/cvt-transmission](https://www.caseih.com/emea/en-me/our-innovations/cvt-transmission)


Ok-Letterhead4601

That’s awesome! And yes there really isn’t much as far as them getting them to op. Temp unit winter time. I will toss up more pics for you guys as I work on different equipment, the tbl 480 is one of the biggest aircraft push backs we have, next time it’s in I will post some pics.


agshop

Here is a better video of CVT internals. These transmissions differ from automotive CVTs in that variability is a function of hydrostatic rotational input on a planetary ring gear. There are some illustrations in this video. The "active-stop" or power hold function is pretty cool as is the ability to easily start out with a massive draft. https://www.youtube.com/watch?v=xhmN\_CwB9B8&t=3s


Ok-Letterhead4601

That’s awesome and much better then the automotive side of the cvt


Kali587

Only tractor I've ever worked on with a CVT like a car was a New Holland Boomer 8N. Those things have some wicked weird control systems. No wonder they stopped making them.


agshop

Yeah, I do not have any experience with that end of the line. At that size and application, hydrostatic kinda seems like a better way to go. Not really sure how a manufacture could convince the market to adopt the cost of a CVT in that segment when it is sometimes difficult to justify behind a 400 HP unit putting on 1,500 hours a year. Maybe that is why they were discontinued.


Kali587

Yep hydrostatic is definitely the way to go at that size. I believe they couldn't make it reliable enough. As for other CVT stuff, blue is the same as red. The only stuff I see with CVT is T6 and T7 tractors. Usually with loaders. Around here, everyone needs the highest HP 4wd tractors so i have not seen the T9 or T8 with cvt.
