I would inspect the spart engine carefully, stored for 10 years, you never know. If it was in a stable temperature dry place maybe. It could be stuck by now if in a damp place or changing temperatures. Did you turn it over from time to time? Did you pour oil into the cylinders from time to time? Check it carefully. The running engine. If the clutch isn't slipping, I wouldn't worry about it. They last a long time if you don't ride them. Grease the throwout bearing once a year or so and don't worry. The front seal is easy if you support the front of the tractor and take off the front end stuff. Even if you have to pull the head and have it done, that isn't hard with the hood off. Get a reprint of an AC service manual. As for removing the engine , if you support the rest of the tractor it too isn't hard. If you do replace the clutch the only thing to do is to make sure the clutch plate is lined or centered when you bolt the clutch pressure platae to the flywheel, you need a dummy clutch shaft to do this, make it out of a wood dowel. Turn it to fit the pilot bearing, then the inside of the spline in the clutch disc, use it to line up the clutch disc as you bolt up the pressure plate. The closer you get it the easier time you hav getting the engine to slide onto the real clutch shaft in the torque tube later. You need a way to lift the engine and then roll the back of the tractor away from it. It helps if you do thes on level paved surfaces, but smooth level dirt or garvel is ok too. Be very carefull if you try to remove the engine and front end as an assembly, it is very unstable. Better to do it is peices especially as you need to get to the front seal. Ask here if you have more questions. Or go over to the orange page.
