Combines Deutz engines in used R62 s

A oil gauge that stays down on a side hill is a problem. I had a R-62 that when it was on a right hand side hill the gauge would jump a little. I put about 1800 separator hours on it, and over time it would get worse and worse, until it quit jumping, and just stayed at a low oil pressure. Then the engine blew. So, check and see if there is a jumping oil gauge, not only to check the sending unit, but also to see if the engine is bad

I have a 6 in line Deutz air-cooled engine in a combine with more than 10000 hours and i have no problem with this engine. I only chnage the filters and the oil every 200 hours and clean the cylinders every day.

Oil leaks are the killer. On the rotor side of the engine is a cover plate on the side of the engine. If you can remove it look for dirt build up. This is a hard place to keep clean and a little oil make it worse. The engine is a horse. It will work as hard as any engine, and you have to blow it out like you would a radiator. Other than that check the fan, this has to be in good shape, if it does not move the proper amount of air thats a bad thing. If it is moving the proper amount of air, I have not had to blow out every day, maybe every three days unless in very dirty beans that water has been on and left a coat of dirt.

Thanks for all the help. I really appreciate all the posts

I'm a little late here Jim but I though I would give you my $.02. Weather you are looking at used air cooled or water cooled you will have very little idea if it had ever been over heated in the past. After you start running them is when you may find out there had been a severe overheat at one time. I think it would be much harder to over heat an air cooled enough to cause damage. Air cooled machines run very hot around the jugs all the time and do not have the gasket for sealing anti-freeze coolant in its proper place. You get the coolant above boiling point in a liquid cooled engine and problems come quickly. If you can believe this I had a custum harvester braging to me how good the Deutz engine is for it was within warrentee and had an oil leak from gearbox that drives fan. He kept running machine and had jugs plugged very bad but could not blow it up. There is a service bulliton on the wear limits of the V8 fan blade and Agco had a 4 year no deductible warrentee on them. Blades wear worse if running with other machines or threshing very abrasive dirty crops. In our area if area between rotary screen and blower was sealed up well we wouldn't blow out motor for a year or more. As soon as we got radiators back we were blowing them out nearly every day. Although doing some tuning on rotary screen area ,similiar to what 2000 machines have, would help a bunch. I had a Deutz powered machine where oil pressure would jump when stoping or starting out fast so I checked a bunch more machines on the lot and they all did the same. I have had dipsticks that are positioned wrong so you can have to much or to little oil in engine. To high of oil level the crankshaft will dip the oil and fill oil with air which will cause oil pressure to jump. I've had l10 and M11 Cummins where oil was to high so crank would dip oil. I don't have hills to run machines on but if I would turn a circle fast the oil gauge would jump around. Turning the circle was enough for the crank to catch the oil so all we needed to do is lower the oil level a bit. Ends up they come with a new remarked dipstick for the M11s and we refilled the empty crankcase with proper amount of oil on the l10 and reset the dipstick accordingly. I wonder what the guys in the severe hills of the PNW do with oil level so it will stay steady when about tipping over. It would be a complete toss up on which engine I would want in my R62. If you get the air cooled I would suggest to get the valves set and do the injectors. Good luck.
