This is my brother's sons' tractor. It's developed quite a noise, I'd call more like a buzz or raspy hum, somewhere between the flywheel and the final drive.
Just a few observations from one who has little to no acquaintance with Ford or NH tractors built between 1964 and 1994
1. This tractor is not equipped with dual power.
2. Loading the hydraulic system exacerbates the noise.
3. Changing the clutch pedal position alters the noise, but it sometimes makes it worse when engaged and sometimes when disengaged.
4. I had the nephew drive the tractor a little over a mile to get it from the field into the yard. He claims the noise disappears in 8th gear at road speed.
5. We did change both hydraulic filters.
6. I noticed the appearance of the presence of moisture in the center housing oil. I'm assuming transmission, hydraulics and final drive are all a common sump on this tractor???
Some questions then.
1. I have an 8000 service manual. Is the 9600 transmission and hydraulics similar?
2. Is there any fairly common cause for this complaint?
3. Am I wrong to figure they're looking at a front split as a bare minimum?
Thanks!
