This post is a continuation of the struggles I've had rebuilding my 1010RS. As a catch up: tractor started running really rich with no warning last summer--in my foolishness I thought the enigne was giving out because it already had low oil pressure and started a rebuild of the mains, rods, and cam bearings (lower half of the engine. Did not touch the head or cylinders as I'm ok w/ where compression is right now). That was completed around thanksgiving but I spent the next months (until now) battling the flooding problem and poor spark. I'm a college student so I only go home on some weekends. Well I'm happy to say that I think I finally figured out the fuel and spark problem, but my engine has seized. I haven't run the tractor more than 10 mins since the rebuild but have cranked it a lot trying to figure out the fuel problem. I'm preparing to tear it back down, but wanted peoples thoughts/ideas on here of what I did wrong. I have checked the main and rod bearings, and I can see oil dripping down from the caps, and I removed the no 1 main cap and the no 1 and no2 rod caps, all of which had a film of oil, and my pressure guage showed 60 PSI the few times it ran. At one point I got the tractor to run for ~5 minutes, albiet poorly, but it screeched to a halt and it sounded like it came from the front of the motor. I'm suspecting its in the cam. As I've been looking into this, I've also discovered that the front and rear crankshaft seals (which I replaced) are both leaking, so I've got to fix that as well. I am attaching pictures of the rear seal, as well as an image that shows the no 3 cam bearing with oil pooled at the bottom, which makes me think it was getting oil. I don't suspect a valve problem because I didn't have one before the tear-down and none of my pushrods are bent in the slightest. Anybody have any ideas or suggestions on what I can check or what I may have done wrong? I won't be home again to work on it until Friday, but plan on putting the engine on a stand and removing the cam to see whats going on.
Also, completely unrelated, but the service manual calls for a special "clutch disk centering tool" to be used when reinstalling the clutch. Do I really need to be concerned about that or can I just use the shaft that connects the flywheel to the powershaft to center it when I put it back together? Thanks!
