R62 Deutz engine

I have been hunting for a nice R62 Rwa and came across one with a Deutz engine. I’ve seen it discussed on here many times and I’m aware of the differences of opinion on the Deutz. It was a nice clean looking machine with lateral tilt 25’ head and 360 hugger head. He seemed flexible on price but we didn’t get to haggle at the time due to trying to get crops in.

My question is. How hard is it to swap it out for a Cummins if I buy it and the engine craps out. would $10k buy a decent Cummins out of a salvage machine. I was thinking of offering $15-20 for the whole package. All opinions are welcome.

I watched a newer one with Cummins sell last Saturday for $25,500 with 25, 8200 head but it was a little beat up.

My mistake. Fat fingers. 630 hugger 6 row 30”. He put the lateral tilt from a salvage machine. He said it worked. I didn’t catch the head model number but I think it’s newer than the combine. I met him for work completely unrelated and only had 10 minutes to look it over. Basically all the sheet metal was strait and everything was clean and in the barn. That’s the basis of my assessment in 10 min. I told him I was scared of the Deutz and he said don’t be afraid to make an offer. He wouldn’t be insulted. I told him we would come look it over after beams were all in and he agreed.

We are going to look at it tomorrow. I know the conventional combines well but the rotaries are new to me. Can someone give me some of the major wear areas to look at and how to tell if they are worn out. Such as rotar bars and cage. How thick should the teeth be.

Also what should I be looking for on the Deutz.

Thanks in advance

Deutz is a good well-built engine as well.

Check the fan on the engine for wear, that can cause the engine to run hot if the blades are rounded and is a high dollar item. As said before, oil leaks are the biggest cause of engine failure. Rotor bars should look the same the length of the rotor, they tend to wear more were the crop enters on the right side. If they are rounded and flat its time for new ones, probably the same as a convetional machine. Also check helical bars in cage to make sure they aren't rounded.

Thanks for the input. Is there a good way to check the feeder house floor. I looked at one a while back and couldn’t find a way to check it out

We looked at it today. It wasn’t quite as nice as I originally thought but still probably a 7 out of 10. First off it was 3 quarts low on engine oil and it has a gilcrest pusher axel with the hydraulic lines capped off. I asked why and he said they heated up when going down the road and he didn’t know why. Then I noticed the hubs were engaged. He said he never could get them to disengage. I think that may be the problem but hard to say what else has been damaged in the drive motors. It also has a lot of slop in the shifter and was very hard to find the start position. He also told me it needed a ac compressor.

But once it started it sounded good. The block had some oil on it but the fins all looked clean from what I could tell. The fan seemed to be in good shape. Corners were fairly square. If the cylinder bars are like a conventional they look brand new. I think the accelerator roles were new too. He told me it was rebuilt before he got it. Along with new rattle chains. Tires were 75% or better 30.5s. It’s got a 25’ 500 head that looks average or better. Reel teath are cut off pretty short and standard sickle. The lateral tilt worked manually. It didn’t have the head on so I don’t know if it worked automatically. He started at $30 but I’m thinking of offering $10. There are a lot that makes me nervous. In looking at everything else I forgot to look at hours but he said he thought it had 3000 engine.

As far as the 3 quarts low, remember, this is an air cooled engine, therefore, the engine oil is used to heat the cab. Depending on how much oil is in the cab heating system, can make a big difference as to the engine oil level. As long as the oil level is above the add mark, I wouldn't be concerned about it.

Checking the oil on our Deutz can be fun sometimes. Did you move the little piece of rubber on the dipstick tube before pulling the dipstick out? It can affect the reading.

Just to update. We decided not to make an offer. There are just too many red flags on this one.

Dont be afraid of the Deutz if its had anything that resembles care.

If neglected, the 6 cylinder will scuff a cylinder before a V8 would it seems.

I know a custom cutter that is notorious for neglecting his equipment, and suprisingly he has very fond memories of the Deutz when he had some Deutz powered R62s. "Just make the boys blow it out daily, and they'll run forever!"

I am keeping an eye out for a R62 or a R72, and I will take a Deutz or Cummins in the R72 (since it will be L10 or M11) , but in the R62, I wont take a Cummins. I have a hatred for the 8.3L in combines. Gutless as heck, guzzles fuel. The Deutz will fight a slug or a mudhole to the death, 8.3L will whimper and whine. Its perfectly sized for a 160-200 HP tractor, but it is not much of a 200+ HP combine engine IMO.

I call bull!!!!!!!!
We’ve had had both Cummins and Duetz powered R’s. Hands down the Cummins is superior. We blew our Duetz out and reliability was still horrid. They are cold blooded and have no block heater. Cab climate control is miserable. Fuel per hour the Duetz does better but per acre it’s close. Power wise the 8.3 in my 7580 pegged the dyno at 220hp at a whopping 1600rpm imagine what it would do at the rated 2300?

Most engines will show more hp in overload rpms. It's just a fact. When a guy who farmed right next to the CaseIH dealership I worked at traded his Deutz powered R62 for a brand new Cummins R62, he hated the Cummins for lack of power and its increased fuel usage. He sent it to Iowa to get it hyperized, and still didn't like it so he traded for a Lexion and has been Lexion ever since. That was back in the very late 1990's.

You had a 6 cylinder R52, correct?

I have not ran one, but I will take your word for it that it wasnt that good. Going off the parts sales, Mikes equipment seems to sell out of the 6 cylinder quite often.

But, Have you ran a Class 6 or 7 with the V8 Deutz? If not, I would hold judgement till you do, they are quite gutsy and great on fuel. GPH and GPA figures are both excellent.

The torque rise may be decent on the tractor application, but for a combine to do a good job she needs to be at rated RPMor close to it, and the initial pull down is where the 8.3L sucks. poor top end recovery. In a R52 I bet the 8.3L is a hoss, but going from a 816 cu in V8 (or 779 twin turboed depending on year) to a 505 I6 in the R62 is a let down.

We got 3 8.3 Cummins 1 in the combine, 1 in a tractor and 1 in a semi. The semi is a bit under powered but the tractor and combine are great. I’ve backed off a lot less times for the 8.3 than I did the Duetz. The 8.3 in my 7580 has plenty of power to wreck the drivetrain.
