Ken, some of the bearings are a little different.. Basically on all bearings look for signs of pitting down inside on the inner race [use a strong light & magnifying glass],, look for brinneling on the balls & races, look for excess shaft play while still in the bearings, look for non-round balls or rollers.. Give them a spin & feel for roughness.. On the ball type bearings look for excess radial or lateral play between the balls & race, look for pitting, look for balls touching due to ball separator wear, & look for discoloration due to overheating.. On the roller bearings look for signs of non-round rollers, brinneling on the shaft or inner race, excess radial play, signs the rollers are wearing through their end retainers, roughness while turning.. ~If when putting it back together you can't set the shaft end play even with all the shims removed, suspect the bearings are worn & have excess lateral movement.. ~On the gears, look for excessively chipped teeth, looseness on the splined shaft [might also have shaft wear], excess wobble while spinning on the shaft, worm teeth sides, rust pits.. You can tell a lot about the gears by how it stayed in gear & how quiet it ran before disassembly.. The good news is those gears can by quite bad & still function properly.. ~On where to buy? On the bearings, try Deere, in a lot of cases I have found Deere cheaper than the bearing houses on some bearings.. If Deere doesn't have the proper bearings probably neither will the bearing houses.. Some new Departure bearings are hard to find.. Every time I see New Departure on the bearings I kind of shudder as I know the possibility for problems in finding a replacement is high.. Basically just call around to Deere [that will give you a price guideline], then call the local bearing houses like Detroit Ball Bearing or Federal Mogul, or even your local auto parts store.. If you really get stuck on a bearing give me an E-Mail as I have a few places that can probably help but keep in mind those specialty bearing places are quite a bit more money.... [email protected]
