BX22 Propeller Shaft CV Joints

ehenry · Oct 29, 2015

I have the shaft out of my tractor to replace the HST fan, CV boots and both joints. In looking at the parts diagram of the CV joint, it shows O-ring dampeners under each ball in the joint. The joints on this tractor are the original joints with 1300+ hours of run time and I have no clue how long they've been running with no boots. When I removed one of the joints from the shaft, I cant find any O-rings under the balls or where they might go other than they just lay in the cup that the ball goes in. I guess its possible that over time with dirt and grime the O-rings got chewed up. Can anyone that's replaced one of these joints on their BX share a little wisdom?

I can't find the thread, but I believe techman has done this.

Stopped by local Kubota dealer to see if parts had come in.....they had not but I did talk to one of their mechanics about the o-rings and he couldn't give me an answer cause he had never done one. He looked up the same drawing I did and said it sure looks like all the o-ring does is sit in the cup under the ball. I'm still hoping someone that's done this will chime in to say for sure.

Based on nothing but pure ignorance: any chance the o-rings are just to retain the balls during assembly? Can't get a mental picture of it - just wondering...
