Combines Seperator clutch Bearings again

[tbran]

I am assuming you are talking 71116581 and 71338182IJ We have had some discussion before on this, I checked our sales - the 71116581 fits a bunch of older machines. Units with a lot of difference between sep and eng usually have more problems. We have sold 1- 71338182's in three years and about 20 - 71116581's only 4 went on R series. We have several units out as well besides the 65's 75's several with a thousand hours. Is this the brgs you are describingIJ - or is it the RH main clutch shaft brgsIJ Would like to know and if you do a lot of roading of combine. Finally I think Dan had some comment on this , DanIJ.

Probably 75 more engine hours than seperator at this point. I am talking lH Bearings the ones that do not spin when the seperator is engaged. Bearing n 71335182 and 71116581 from an older parts book. May not be current number. Oh, they will probably not totatly fail for a long time. That clutch area is just a sore point for me. John Deere would never get away with something that crude.

Check that the howl is not coming from the header engagement clutch bearing in front of tyhe main clutch. It can be very hard to tell the which clutch bearings are howling in this area. We got caught this way. Also check the amount of grease in the bearings by carefully removing a seal. The last lot we got from AGCO had about a 1_2 to 1 teaspoon full of grease in them. The howling bearings we replaced had not failed. They simply had no grease in them and were running dry.

I hear exactly what you are saying. I'm glad it is easy to put in and rarely causes any additional problem. This is actually nearly a 20 year old issue if you count the R40-50s. I disagree with you on this being a stupid setup. I think the setup is excellant but needs to be refined. We have a couple years of testing on a double ball bearing which is 1_3 wider than original. We need to deepen bore in pulley and narrow up the spacer between bearings by 10mm. I have not heard one of these growl yet but check with me later on and I'll check with another guy that has put a bunch in. I have a good feeling that Gleaner has the wire harness between clutches fixed now. I would like to see them put on the double brusholder used smaller machines to reduce voltage drop but I have so little to no clutch trouble that I don't see that a priority. Buss me an email and I'll get you a picture of bearing. Take care

Dan, what is the make and number of the double row ball bearing, please.

like you said it could be made better by doing something like you are doing. But, when you are running multiple new machines every couple of years, you are not going to go out and get every one of them machined right off the bat. No, the wires and brush holders are not fixed yet. Using wire ties to keep wires from getting cut is not much better than using baling wire and duct tape to fix everything. Yes it is easy to access, but it all takes time. I would put up with it being hard to access and hard to work on if you did not have to work on it. The stupid thing is waitig 20 years for it to be refined.

Oh but I disagree here, let me go on a rant, take a look at Sikeston and the alum gear boxes that go in the Deere grain bin, hopper bottoms that last less than 1000 hours , rock traps that don't, cylinders that snap off tines and take days to pull and repair instead of hours and on and on - what about the engine crankshaft problem - the big 9something liter eng had a rod brg life problem - they cross drilled the crank and changed block casting plants, now the cranks broke - EVERY crank had to be changed, combines, tractors and cotton pickers etc , customers are told they now have a new beefier crank, it is true, they went back to the old non cross drilled crank.... A friend who told this to me is inventory sales mgr for 5 deere stores - he said to the deere customers this is a non event.... if anyone thinks any company is differentIJIJIJIJIJ Deere gets away with what ever thay want to ,,, only class action threats such as the first articulated 75XX 4wd's trannys change their actions in many areas. Finally what about the 9400 combines, we had one in the county that didn't have the power to shell 6 30" rows uphill with a full bin. The service rep from deere came, looked, diagnosed and told him he was expecting too much from the unit. The customer told me in exact words "I showed deere - I traded for a 9500..... " and on and on ad nausium

we too, or I also had the same occurance, but my brgs had a few thousand hours on them, but the howl was the same. Only thing was they made a noise only when the header was turned on. Opposite of what is described here.

 

[magnum_man]

lOl. Yea he really showed them. You got to love that kind of loyalty.

I understand what you are saying completely. There were only a few proto type wires put out this year so I'm not sure you have got one. We have replace piles of inner seperator clutch bearings in the past 20 years and only a couple went so long as to hollow out the pulley. I just don't like them getting noticeably noisy within 500 hours. This is why we are looking for a better answer. I'm hoping Gleaner will copy what we are doing or come up with their own plan soon. When they fix this they should have the passage way for wire cast into pulley. I can't complain to much about wires for I'm sure 75% of the machines over 20 years have original wire. I'm sure well over 95% have original clutches. This is why I love the simple system but I would love to get rid of the premature bearing growl. Have a great day.
