I doubt it but it might. I have a JD 630 that I'm just finishing up installing a new slinger seal. Was a simple job except for removing the flywheel. Previous owner had buggered up the lock nut threads at the end of the crankshaft so there isn't any lock nut to set the end play. The splines were also very rusty and filled with paint and grit so it took a lot of effort to get it off. I built a puller to finally get it off the crankshaft. Cleaned up all the splines and grooves and it went back on very easily. The oil slinger has a slot that must be aligned with a square pin on the flywheel. Make sure to check that the flywheel and crankshaft V markings are lined up. I also used a finishing punch to mark the correct alignment. You will need to move the slinger groove to accept the pin on the flywheel. The slinger seal is a square (round) seal I bought from Mother Deere. My outer thrust bearing/gasket was torn so I had to replace it. When you put the housing that covers the slinger back on be sure to use shims to get it perfectly aligned/centered with the crankshaft. My ITT manual is very good describing the process and settings. Had to loosen up my starter to get the flywheel off. Bought new grade 8 bolts and nuts, fine thread to be safe. Torque figures were around 285 ft pound but I have a 600ft lbs manual torque wrench so that was not a problem. Some people use a multiplier or a 3/4 or 1 in socket and a three ft cheaper bar to approximate the torque. Be sure to check it again after you run the tractor for a few hours. That flywheel is heavy so use a engine hoist with a nylon axle loop to remove and replace the flywheel. Not easy but I did it without any help. Have fun.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
