Done with combining but trying to get a jump on next year.
When finishing corn with my N6 I noticed a new noise.
When I engauge the rear end(rotor) I have a strange noise coming from the area below were the magnectic clutch is I believe. It doesn't sound like the usual bad bearing but more like metal rubbing howl. Not sure if it's my imagination but when I stop the rear section it seems to time out for a bit before the rotor acutally starts to slow down - I am assuming this is something that was done to get all the grain up in the tank and out of the rotor. The strange part is as soon as I hit the button to disengauge the rear the noise stops even though the everything else is still running until it times out.
Any suggestion as to were to look would be helpful..TIA

G'day there, might be able to help. Had the same metallic scream myself. Check the bearings at each end of the fan. The bearing on the driven end had totally failed on my N6, due to the drive belt being way too tight (I bought the machine second hand). I was lucky I did not have a fire.

You may have a more serious problem than a bearing. If you can have a second person in cab to engage seperator clutch switch and at the same time watch the seperator clutch engage looking back through removeable cover below cab next to feederhouse. When seperator clutch engages there should be no movement of two shafts where seperator clutch pins are located. We have seen locknut come loose on inner shaft and it starts to let drive pin asy. work on shaft and key and the noise you describe is the seperator clutch trying to center itself but it is actually rotating out of round and making header clutch bind causing metal to metal chirp. We have seen this on several of customers machine over the last 25 years. If you can get lucky it has only worn the drive pin asy. and not the RH seperator shaft where drive pin asy. keys to shaft. Then you can find a used drive pin asy. in a salvage yard. We have also seen the inner spherical bearing fail but if you have been greasing this should not be the problem.
