I agree w/tx most salvage yard balers have had all of the goody used up. Either burnt up or completly shot, sprocket most likely will be tough to get a decent one might have some luck on the roller but will probably still need new bearings. Haying is an expensive hobby and older balers can certainly nickel and dime you to death. 375 balers are getting close to 23-24 years old now so have seen quite a few acres. I would search for another complete baler to purchase so that you can rob parts to fix the best of the 2 units. Good luck
