Well first off I'm new to this forum, new to this tractor. Really pretty new to ANY tractor. But I have a Massey model 20 with a 3 Cyl Perkins gas engine. I had a terrible oil leak and low oil pressure. I had read that the suspect was most likely the oil galley plug. I split the tractor and sure enough there is oil puddled in the oil galley plug hole. While I'm in there I'm going to replace the rear main and oil pan gaskets. My big question is about the clutch. (Which I may also replace). When. I took it apart I didn't put in the slave bolts. I read that part in the manual after I had already buzzed the clutch and flywheel off. So how bad did I screw up?
