I really don't know whether a 13" clutch disc was available on the thousand series or not. I'm pretty sure it was on the "10" series, and was standard on the "30" series. Lord only know what somebody like "me" has done to your tractor. A couple things come to mind though, on why this isn't working right for you. The first would be a bad pilot bearing. That would cause grinding, if the bearing was binding up.
Second, the larger disc is heavier, and would have more inertia, and would take longer to stop turning when you go about shifting. Those, however, would not effect the clutch engagement or free play.
The other consideration, regarding the free travel, and correct clutch engagement is with the length of the clutch bell crank (fulcrum) on the outside of the clutch housing, and as a consequence of that, the internal lever. Suppose you have a 30 series clutch, which I think you may. If the 30 series had longer levers internally and externally, which were made to give more lateral travel to the release bearing, and your tractor has shorter levers and linkages, it would not have the same travel. If you have 1" of lateral travel on a clutch that might require 1.25" to release properly, then there will be a problem like you describe. All I can tell you is that somebody will have to sit down with a few parts books, and see what was available on the thousand series.... Also,get the part numbers of the pressure plate/clutch that you have. If you get those numbers, input them into NH's part system, and they can tell you what model tractor that part fits. Then just go through the linkages and see what's different, etc. This will require research.....
The only other possibility I can think of would be broken or damaged fingers or a diaphram on the pressure plate.... But you would notice that sort of thing. Dunno. More research, I guess.Rod
