Combines centrifugal filter

Tbran, You are exactly right! I remember at service school in the early 90's the service reps had one of those fluid couplings that came off the wheat harvest that was packed full of dirt and crud from having an intake hose clamp loose and it dusted the engine. The engine had a fair amount of hours on it before it failed and Gleaner felt it would have failed a lot sooner if it hadn't been for the hidden filtering system(Not what it was intended for.) that the Deutz engine had. Man,you think you are getting old,I had totally forgot about this,thanks for joggin' my memory. Must be something the MIl are feeding us without knowing so we will start to like them.

Oh I don't think she could ever forget you! Did you have any damage from the storm that went through last weekIJ It looked like it was headed right in your direction when it crossed the river. Weatherman in Memphis said he sure wouldn't want to live near Dyersburg...said he's seen more storms in that area in the past 2 years than in the past 10 total.

Not many get cleaned, but an early indicator is often overheating. When that gets plugged, it slows the cooling fan, often resuling in complaints of overheating.

No damage here, yes damage along Miss river. I think we are the new 'tornado alley'. I did see one up close and personal 2 years ago. I put all emplyees in the middle of the building and went out to look, darned thing came up over a little ridge 653 yards from where I stood. ( I went back after changing underdrawers and measured) Split and went around us. I heard it coming and said "lord, please spare my people" then when it appeared I let out a "Oh Sheeeit" and barely made it in the bldg. I then thought that that was not the proper way to end a prayer that had just been answered. But I think He understood and I ask forgiveness. I confessed my weakness and slip of the tongue to our Baptist minister in 'confessions'. I thought it quite non professional that he burst out laughing as I told him the story . He told me to look up and do a few hail mary's as penance , then told me he was sure I was not the only one to end a desperate prayer in a mortal way slip of the tongue. I can tell you seriously , witnessing a super tornado that did millions in destruction is not something I ever want to see again. BTW on the Weather Channel, Storm Stories, Glenn lee was featured as one of the homeowners whose house was destroyed. It we less than a mile from where I sit. We have had 3 tornados touch down less than a quarter mile from us in the last 10 years.

Interesting thoughts going on in reference to cooling fan centrifugal filter. Harvester, you make a valid point on overheating, for I have a machine out with fairly new fan that was starting to have some heating problems this summer. We have cleaned this centrifugal filtration bowl when installing new fan, finding a sometimes medium to moderately thick layer of dried oil crud. Seems to be quite effective in filtering contaniments out for protection of fan drive on V-8's. Makes one wonder why this couldn't be cleaned out earlier in order to prevent overheating, because the fan does not get replaced but every 600-800 hrs. Harvester, can the centrifugal filter be serviced by removing the aspirator screen intake(rotary screen basket)IJ Or does one have to remove whole fan housing just like one does when replacing fanIJ

Not sure. It will take a better Deutz expert than I to answer that. We have always cleaned them to coincide with the fan replacements, or at very least, removal for inspection.

I think you would have to be quite a monkey to get front cover off blower and then the cap that will hold the grud with blower still installed. I have not found where cup has filled enough to cause heating but of course it allways gets cleaned out when replaceing blade so it maybe it is part the cause. Beings you just had replaced blade and cleaned filter you might be better off spending your time removing main oil cooler. You can than clean this very well and get at the thermostat under cooler. While replacing thermostat be sure to replace plastic nipple near thermostat for I believe this gets worn and may well be allowing oil to bypass cooler. Don't know for sure but was told by Deutz expert to replace this nipple anytime thermostat is being replaced. Average life of blades in our area is 1500 hours. Some way more and some less. Makes a huge difference if running with other machines which are putting dust in the air. Blades in the tractors often run 7000 to 10000 hours. I don't service centrifical filter unless replacing blade. Combines with V8s have very large bypass filter which I would hope keeps the oil as clean as it needs to be.

NDDan quote:[I think you would have to be quite a monkey to get front cover off blower and then the cap that will hold the crud with blower still installed.] I had a good laugh when I read that. I believe that you are right about that, although there have been times when I felt like a monkey crawling into various places on machine, and especially when one thinks he can knock some time off a particular job. I am intending on cleaning main oil cooler but just leaving it intact. Sounds like a good idea to simply remove from engine in order to give a more thorough cleaning. NDDan, you mention of the thermostat under cooler with plastic nipple possibly causing oil to bypass cooler. I definitely think you are on to somehting here, for we have never replaced thermostats on either machine. Is this a fairly easy jobIJ NDDan quote:[Average life of blades in our area is 1500 hours. Some way more and some less.] I previously stated a fan life of 600-800 hours, but on other intervals the fans in both combines lasted around 1100-1200 hrs. You are right about the machine running with others. For these first 2 R-70's were bought new from local dealer. Then as farm grew 2 more R-62's were added for total of 4 machines running togehter. {Now R-70's are running seperately, with one 89' R-70 having 2993 hrs. and other 91' R-70 3200hrs.} That was always the rule of thumb with all the operators to stay out of the other machines dirt. Whether it be milo or wheat, cooling capacity would stay sufficient all season long. NDDan, Thank you for sharing your knowledge on this subject.

I have cleaned cooler with everything intact but you don't get a good job done. I have rodded all passages and then did good job with angle nozzle on pressure washer with blower out but that leave quite a mess to lay in when reinstalling blower. If blower was recently rebuilt I would tend to want to leave it alone even though cooler can be more easily removed if blower is out of the way. I can't seem to remember to ask tech at shop what all exhaust has to be removed to lift cooler off studs while blower is still in place. It may be more than just the just the heat shielding over turbo but that is the way I would attack it. Hope that helps you deside which way to attack it.
