After finishing cutting 2 fields yesterday with a rotary cutter, I noticed a clanking/rattling sound when the tractor was idled down before shutting it off. It's a sound like a thicker steel cover plate that is loose or something, but it's definitely inside the transmission and seems to be located towards the front, say in line vertically at where the sheet metal starts just in front of the 2 gear levers. It does not sound like something from the clutch assembly as the bell housing is further away, unless it's a deceptive sound transferring through somehow.
It goes away when you depress the clutch pedal. It's most prominent at low idle, and when you shut it off, as the engine slows to a stop, it slows at the exact same rate.
Biggest question is, what inside this transmission,(8 spd w/mechanical shuttle)would let loose to cause this ?
Little history on the transmission, 4th has always made a whine, 5th started doing this later, just a little at lower RPM, and when I first got the tractor, the transmission was overfull by 5 qts.
Last September, I completed a full service of this tractor, including the transmission. Drained that out, removed the screen from it, took it apart, and meticulously cleaned it. I found a small quantity of metal fines, about the head of a pencil eraser in volume + or -. Replaced the gasket and o-ring like was recommended here by Destroked 450. Glad to know about that screen. 35 hours of use since the full service of every fluid in the tractor, including the front drive axle. Tractor runs great otherwise.
PTO, works the same as it did, finicky to engage smoothly, full power to the mower.
Prior to this, I did shear a couple of grade 2 bolts on the shaft, the mower was set a little too low in the front. It cuts better that way, but will scalp Tussocks or Hummocks, (those big tufts of grass you find in a marsh) on the edge of this field. So there were some shock loads, but those grade 2's shear easily, heck if you have the throttle up a tad when engaging the PTO, it will shear one. Was suggested to raise the throttle a bit when engaging, make sure the pressure is adequate at the clutch pack I assume. Long time ford tractor mechanic suggested this, seems to work.
I've got the full manual set, will look over the transmission section, but have resigned to the fact that this will likely have to go to the shop and could be very costly. Also parts might be difficult to find. Tractor now has about 1310 hours on it and has the original working hour meter. Odd with such low hours to have a problem like this, must be more to this.
