ck25 hst pedal

[harold22348]

I have a2008 ck25 hst and the hst pedal is extremely hard to move..any ideas?

There is undoubtedly a neglected grease fitting on the pedal pivot. Grease it. You probably have to take it apart and clean it out first.

i have cleaned, lubed and disassembled the whole assy... there are no grease fittings... the shaft for the pedal goes into the trans. when the split pin for the pedal is removed the pedal moves freely and everything works normally. when i put the pin back in it is very stiff and hard to move.. dangerous... the shaft appears to be binding where it goes into the trans case... could the cruise control function be causing this even though the cruise is disengaged and moves freely?

Did this binding shaft into the trans happen over time, just gradually getting worse or suddenly like just one day it became stiff?
Why do you think cruise would have any influence on the shaft movement?
When did you last do filter/fluid service on the HST?
How many hours on the tractor?

Could the shaft simply be bent?

 

[harold22348]

it happened all at once.. tractor is serviced by the book and has just over 600 hours, I suspect maybe cruise because when I would use it, it would ratchet into cruise and release. now it just pops in and out.. cruise lever on trans moves freely and has same style shaft as hst pedal. the cruise shaft has end play and moves freely whereas the hst pedal does not. I removed the retainer for the hst pedal and the shaft will not move in and out (end play) I tried to find a parts breakdown so I could see how the cruise works internally. short of a teardown I see no way to release it if it is stuck. I have only used the cruise once or twice going to the neighbors.. it is not a necessity.

I still think there is a grease fitting below the floorboard.

 

[harold22348]

I had the whole floor off and all linkages to the hst pedal itself off. there is one fitting and it is on the heim joint on the end of one of the dampeners. the shaft is not bent.. it would take an act of God to bend the shaft. there is a seal where the shaft goes into the trans so I assume the shaft is lubed by the trans fluid. if anyone knows where I can get a parts breakdown that may help.. also where is a good source for parts. I need a fuel level sender and seatbelt retractor... the dealer in town here is no help and the next closets is 2 hours away.. it took them 45 minutes just to find my filters the first time I went in.. so I saved the labels with the part numbers just to make it easy on them and I crossed all filters except the 2 hydrolic filters over to wix numbers...

try a kioti dealer if there is one close by.

First, forgive my mechanical ignorance.

I know over in the Bobcat forum there have been conversations about lazy hydro pedals. (I wouldn't call your description a lazy pedal). I seem to recall some of that conversation mentioned a possible relationship between cruise control malfunction and
the lazy hydro pedal.

Take this info. for what it's worth.

Try MIE, they have online schematics, parts manuals and service manuals, both of which you should buy to service the problem. Michigan Iron & Equipment, an approved TBN advertizer.

 

[harold22348]

thanks...

 

[Coyote machine]

You're welcome. Realize there are no online service manuals, just parts & schematics of systems. Some things are only available via paper softbound.

I have had to replace the shaft. It broke flush with the housing. It is possible. I had the lazy pedal from time to time before the replacement, but it does not seem to be a problem any more.
Is there any chance you could be missing a return spring. Does it hang in only one direction. I can take a photo of mine and send it to you if that would help.

 

[harold22348]

it hangs up in both directions... there is no return spring.. it actually takes 2 hands to move it from forward to reverse and back... and when it does move you can hear it creaking.. it is so hard to move that it broke the split pin that holds the pedal to the shaft.. with the split pin removed and everything back together everything works normal and freely.. i just need to find out why the shaft is binding short of a tear down..

My tractor is a re badged Kioti so I thought they would be similar. My tractor has a return spring on each end as I recall. I know you don't want to hear it but, I think you may have an internal problem. They replaced my shaft for about $300 as I recall so it might not be as bad as you expect.
Good luck

thank you.. i just have to find someone to work on it... the dealer here is questionable at best... we do have a john deere dealer 2miles away... they have always been very good...
