I am a John Deere service tech and the other day we had a call from a customer with a 9550 and a bad vibration...
So I go and check it out and the primary countershaft is vibrating in its gearcase. As I am pulling this apart, I discovered a grease zerk behind the electric clutch. The owner of the machine was helping me get the clutch to the ground and he said "Well I never knew that was there."
On a 9550 the service chart is right on the ladder; he quickly pointed out that it wasn't on there...I told him it was probably in the book. Looked in the book and there was nothing. I pulled up service advisor and could find no reference to this grease fitting on the lube chart, and on our 2 combines, a 9550 and a 9560 STS.
I took some pics to show where it is, and show that the diagram is not there, nor has it ever been greased. I also worked on a brand new 9660sts, happend to glance at it as well. No reference, and the fitting is still there
Has anyone else seen anything like this, known that this fitting was there, or had problems? No one at my dealership knew anything about it
Heres the pics
