Yes, the wear ring and wear sleeve is the same.wear sleeve and wear ring are the same? did checked the chain links yesterday.. remember i mentioned before that 1 is longer than the other.. both has the same number of links.. so i checked the connections. the longer one has bad connections. there's a lot of play in every links thats why its longer. I have good news found the remaining bearings.. now i need to follow up on the chains. got 10w30 for the chaincase.. yahoo.. bad thing is i didn't started the hydro pumps. and lines yet..
Wow, i'd never suspect one chain to wear like that and the others all be ok. All 4 run in the oil bath, so you'd expect them to all be in the same state.
Glad you found the needed bearings.
When you install the gear reduction boxes, make sure you adjust its location to have equal slack on the front and rear chains.You should be able to slide it forward and back.
Also, as you opened up the drive motors, make sure you put thread locker on the threads of the 4 long bolts, not the 4 bounting bolts to the reduction box. This will prevent it leaking oil back along the threads and out of the heads of the bolts. It won't flow, but it 'can' weep out of here if the threads are not sealed.
