Well please don't go nuts. It can't be that bad. The clutch on the 990 is one of the easiest ones there is. It's has the huge advantage that you don't have to break the tractor in half. Assuming all the bolts are free a good mechanic could have the clutch out in about 2 hours. There is no brake band over the input shaft. There are a number of things that could cause the clutch to fail to disengage. The clutch is kind of unique because it's inside the flywheel. Maybe that's what someone thought was tricky but it's not. If you don't have enough clearance between the clutch and sides of the flywheel or if the pilot bushing is to tight the clutch will not disengage properly. To diagnose the problem disconnect the shaft from the transmission and turn the shaft it by hand. It should turn easily with the clutch engaged but I bet yours doesn't. Try and determine were the drag is. How long it should take is hard to say. There are so many variables. It would take me about 5 or 6 hours to remove and replace a clutch if I had everything I needed and I did not have any problems. But if something is stuck it could slow you down. That 5 or 6 hour estimate does not include any time machining. The flywheel cost a little more than most to machine because it has three surfaces to machine. Most only have one. It's going to be very hard to find a steering assembly. Is it the steering gear box or the bracket that holds the steering gear box? Your best bet is to try to have it welded. Hopefully I've answered your questions but if you more post on the Oliver board before you go nuts.
