These are the "scarf" cut rings. We will be installing solid Teflon pieces. from my reading the solid seals better and with the big cut in the "scarf" cut I can see why. The kit came wth the cut pieces so I ordered a bag of the solid as I read that they are hard to install. I figured I'd hurt some but it wasn't near as difficult as described. The ones I put on the input shaft I soaked in some very hot water as I read that this helps them stretch. The set I put on the forward drum I just put them on with no prep. I didnt really see the benefit of the hot water. If you do it and have trouble maybe the hot water would help. Your call.
dish of hot water I warmed up in microwave and brought to garage. Wife not too keen on me doing this ring install in her kitchen. I don't let her cook in my garage so I moved my activity back out there.
sizing tool made from some more of the plastic liter drink bottle and some hose clamps. first work the rings into the grooves with your fingers. Then with the plastic get the rings situated and clamp them down with the hose clamps. I like that the plastic is clear as it allowed me to see we didn't pinch the rings and that they are situated into there respective grooves. Let them sit. I went back and checked on them and repostitioned the clamps to get the rings uniform. After this I was able to get the shaft into the stator support where the rings(two of them) with live.
This part is not for the faint of heart. To replace the bearing down in the planetary one must remove the planet gears and the associated pieces. The snap ring comes off then the real "fun" begins as there are little rollers like a universal joint that the planet gears ride on around the pinion shafts. when you pull the pinion shaft and slide the planet gear out keep track of the shims as therse clearance the gears to the housing and are important to put back where they came from. also those rollers come out so have a clean place to catch them.
I made a couple of scratch marks with a screwdriver on the housing next to the pinion hole to keep track of where the setups came from so I could put them back the same as they came apart.
you can see the rollers in the gear around the shaft. I didn't take pix as my hands were covered in transgel getting these back into the housing. Don't forget the new bearing as that is why we took it apart to begin with.
