  • KX121-3 lots of questions

    Ok so a Kubota 121-3 found its way to my place ,its supposed to be a 2007 with about 2700 hours on it ,not sure I believe any of that given its condition.
    So anyway the pivot pins and bushes on the king post have a fair bit of play and need to be replaced ,question is do they come out reasonably easy or are barstools ?

    Trust you to buy a worn out pile of junk .
    It will depend if all 3 pin contact points are bushed .if not and wear is bad may need lineboring and bushing ,which does not come cheap

      Yep it looks like I'm a scrap collector .
      Hopefully there are bushes in there ,supposed to be anyway but its starting to look like the last owner might have been a butcher not a machine operator.
      This link doesn't go quite where it was supposed to ,its not a super series either .

            Hopefully they havent worn through the bush , I suppose the question is are the bushes able to be to knocked out with a big hammer and drift bar ?.
            A ring of weld to shrink them perhaps.
            Sorting one issue at a time I guess ,it has a few others .

              Burner would be the quickest, they will be pretty solid in there, and a fair size to drift out, unless you have a puller.

                    Well most farmers I know have access to a burner .. but yes.... use string for everything else .. Hey thats where I learned to weld .. if you can lay down a stick joint through shit on an old dung spreader without prep, you can weld anything

                      I have access to gas but I was thinking of using a plasma cutter or lazer. BTW string is only for emergencies, now progressive farmers use Zipties wire and duct tape .

                        Another question for the brains trust , Re the plumbing on this machine for attachments like hammers ect on the dipper ,are the valves two way so they can operate augers and thumbs ect .
                        Its not the super series just the plain old basic uncomputerised 121-3 with the foot operated peddle control ..

                          I guess check if the pedal works in both directions {Heel and toe } If it is 2 way , there should be a valve somewhere that sends return oil direct to the tank .if this valve is set to tank , you will only get one way ,anyway .

                            Yeah I should have tried that first ,probably with the engine off so as not to stress the plumbing pumping into a dead end.
                            There is an unlabled tap above the valve block under the right hand cover, would this likely be the diverter to tank ? .
                            Don't think I need a breaker yet but two way oil flow for other things is a must .
                            Every bloody thing I see online is for the SS 121 ,is the universe trying to tell me something ...
                            Probably need Muz to change the thread title to "KX121-3 lots of questions" ...

                              Some were two way rockers, (depending on series) I cant remember, but the valve you mention will function either as a flow reverse, if the machine only has a single acting pedal or a return direct to tank function as Ian says. In any set up ..it is capable if biderectional flow
