I have a late model L2350 with 725 hrs. When i bought it the fella said the clutch and throw out bearings were replaced. I said how many throw out bearings were replaced? He said all 12. So i don't know if he really had it changed or not. Anyway 3 years later now when i push the clutch in it sounds like high pitched squealing or maybe metal on metal grinding until I let off the clutch. Sometimes i have issues shifting gears with it grinding. I'm guessing it is time to change the clutch. I plan on doing it myself. Besides the clutch and all associated parts should i change any of the oil seals on the transmission or engine since I'll have it split? Is there anything else i should change while I have it apart?
