If the grinding is occurring when you push in the clutch without trying to shift gears, bill has a good point. If the grinding occurs only when you try to shift gears, then the cluch needs adjustment or most likely, replacement. If this is necessary, then, fortunately for you, you have an Oliver, the easiest tractor to change clutches on, except a Deere but they didn't have a real clutch anyway. So, without the belt pulley in there, you have it really easy. Slide the pto shaft out about 3 feet (it's coupled directly to the engine flywheel so it may take some prying if it hasn't been disturbed in a while). Then remove the hood and side sheets to make things easy. Loosen the transmission coupler behind the bell housing and slide it rearward until the shaft coming out of the bell housing can be moved independently of the trans. input shaft. Disconnect pedal linkage. Remove bell housing attachment hardware and slide the bell housing back. Remove pressure plate hardware from flywheel. Tilt intermediate hollow shaft that connects clutch disc to trans. input shaft so the intermediate shaft can be removed. Then remove pressure plate. Check condition of pressure plate, especially the clutch fingers for spring length and strength. These springs will weaken with age so a new/rebuilt pressure plate may be in order. Or you can put washers behind them if you don't want to spend the money. You'll at least want a new friction disc, throwout bearing, and pilot bearing. Reassemble in reverse order. Adjust so pedal has about 1" freeplay. Consult manual on this one, I'm going from memory. Clutch should work fine now. The sliding spur gear trans. on these earlier Olivers could be shifted quite easily, even on the go. P.S. Inspect flywheel for runout or have a dealer do it. This is also a potential problem. Best of luck and have fun.
