    Posted: 30 Jun 2025 at 6:36pm
Getting ready to run some wheat with my N5 and I noticed while hooking up the header that the straw spreader and the sieve was rotating very slowly without the separator engaged, then I heard kind of a bang noise, separator will turn on with the switch fine, but did the same thing when I turned it on and off. Any ideas? Thanks!

Sooooo, you've been faithfully greasing the separator clutch bearing once a week right ???  Or do you even know what I'm talking about ??

Yes I certainly do know where it’s at, weekly? No I don’t run that many acres and don’t put that many hours on it. But it does indeed get greased, hell it only takes me a day to run the wheat I have. That’s why I run a junky old N5 to start with. So you thinking the bearing is failing?

Gotta ask !!! Many second and third owners have not a clue about that bearing. If the separator is creeping on its own, the only way is something wrong in that clutch area.

Try unhooking the hydraulic hose running to the rotary coupler on the separator clutch shaft. Start it up. Do not engage the separator clutch, see if separator turns then, or if oil spurts out of the hose

Clutch pins also could be so badly worn that they are causing a bind that won't let the clutch fully separate when disengaged
