    Bordercollie et al, The Diff Lock was frozen and but now is free, lubed and working properly. This is the first time the machine has had this capability since my ownership. This machine is a Tank/Beast! I have read many articles about lack of speed but for my needs it is perfect with the...

    RTV 900 Moves in 4wd but not 2WD

    Thanks for the guidance folks. Got everything changed out yesterday and have 2WD working again; even climbing hills in 2WD low. Took the better part.of the day getting parts cleaned and doing the U Joint "phasing" wasn't so simple working solo. Rear axle hubs were from Messick's and the...

    RTV 900 Moves in 4wd but not 2WD

    Sir, all of you are a wealth of information and I enjoy reading the various threads that you direct me to. Do you think the worn U-joint would involve "no" movement whatsoever or do is it likely that something else is going too? All of you seem to be very handy, i.e. mechanics/machinist which...

    RTV 900 Moves in 4wd but not 2WD

    Got the machine off the ground today and noticed two things: 1) inner U joint (right rear) noticeably worn with tons of play. No idea about condition of in the inner U joint. Tire turns when placed in F and R when off the ground; 2) tons of play on lt. rear wheel hub. I think the bearing is...
