Sunstrand Foot Control

[Racinbob 12,830]

I have posted an ad for a batch of hydro foot controls. I was just asked if they would work on a Sunstrand. As far as I know they are for Eatons only. Most of you know how the control rod hooks up to the shaft to operate an Eaton. Does anyone have a picture of where a Sunstrand would connect? Would it just take a different rod? Or

Sundstrand motion control movement is vertical..Eaton movement is horizontal

Seems as I remember someone having an external setup on a Sunny Strand. ???

Matts Foot Pedal was made for an Eaton

But he would sell it for a Sundstrand and he would buy (extra $$) some part off Ebay (maybe off an Eaton)

I'll  see if I can figure out what it was.

I made one with a clamp on the motion control rod and a pedal from a 269H along with a couple springs to get it to return on its own. Not pretty but it works really well. Its probably been close to a decade but it still goes fine.

I need to figure one out for a GT-14  I need it because of the FEL

Here,the standard parts in Matt’s Pedal Kit. 

 

For a Sundstrand he supplied this part to convert the motion control. 

Can someone confirm the vertical part is added on to a standard Eaton motion controller.

As you can see from @oliver2-44’s pictures, Matt’s kit took advantage of the existing rocker (Part #11 in this ’95 520-H IPL) by connecting his linkage in the same way that WH did with Part #52 from the column-mounted motion control lever. 

Parts 7-10 and 12-17 comprise the link between the #11 rocker and the Eaton motion control lever atop the transaxle. The rocker supplies “fore and aft” motion to the link. I haven’t seen details (either in person or on an IPL) of how the rocker translates control input motion to the vertical motion that the Sunstrands require.

This is the sunstrand rocker.  I guess if you put a ball end pin in the back of the eaton rocker you could get the vertical motion you need.  I don't see it the picture oh Matts part above.  Also not sure the pivot points are in the same location.

That vertical part is standard.   There is a hole on the rear right corner where you can add a ball stud.

 Are you sure??? ....the ball stud has to come out of the rear of the rocker to hookup with the plastic slider....

Pretty sure.  There is a hole next to the notch in the rear.  Should be where the ball stud goes.  Only way I can see to make it work.   

 

For the record I only have Eatons in 400 series tractors, and have not done this conversion.  Just trying to help.

If that's the hole you're referring to it's not intended for ball stud. The installer has to drill that hole and mount a roller bearing there for the neutral return.

[pfrederi 20,010]

Is there a hole at the Blue arrow that might take the ball stud you need for a Sunstrand...however i don't know would be in alignment with the plastic slider

That's the hole I was referring to in my previous post.

Any progress with the conversion?

I am the one for whom Bob posted/ inquired. Thank you Bob!

 

All of my projects seem to be long term,  and this conversion would not be an exception.  It is still just a concept. 

 

I  currently have 4, mid 70s tractors, all with running k341s kohlers. Three have sundstrand transmissions one is an 8 speed.  At least 2 are C-160s, the other two are probably mutts, haven't really tried to vett them. 

 

One of the mutts,  has a leaky axle seal. I've made a couple of attempts at replacing the seal,  with no luck.  There seems to be a small ridge of metal in the casing that prevents the seal from being seated. I need to get the transmission off the tractor and onto the workbench to assess. If that goes well. This is the one I intend to modify.  

 

Like I said,  it's a long term project,  and will take me a while to get there.  I always seem to have a lot on my plate. 

 

My thought was to attach a tab to the sundstrand rocker, but replacing it with the Eaton rocker makes perfect sense.  These little nuggets of knowledge are priceless.  

 

I would love to here more,  possibly from someone who has made a successful conversion.
