LK3054 accelerator lever question

[hogwash]

I purchased my first tractor past weekend and after spending a week using it. I noticed the accelerator lever that you push forward/backwards seems to not make contact until until almost half way forward. My opinion is the lever was pushed too hard and bent the rod back.

What ends up happening is the accelerator arm is only able to push the RPMs to around 1800.

I know the silver stop bolt/nut seems like it's being hit but it's not and i even moved it up to make sure.

Would you pull the lever off, heat it up and bend it up so it hits the C plate earlier?

Thanks in advance,

John

What about when you use the foot pedal? Does it go to a higher RPM?

Yes. Since it's connected to same C plate (metal rod on left side), it will effortlessly pull the plate counter clockwise and can reach max RPM (verified looking at throttle connection on engine)

I will have to look later today but I think there a way to adjust the link to the petal. You will need to adjust both that linkage and the linkage to the injector pump. I do not believe anything bent.

Okay I have your solution. See pictures below.

First you need to loosen the nuts on the linkage I circled in red. Back out on the nut on the left to about where the one in the picture is located. Then adjust the nuts on the right tight against the lever. This will cause the foot petal to come higher off of the floor indicated by the arrow.

Do not worry about the petal getting higher because the actual engine speed is controlled by this stop circled in red on the injection pump.

That will allow The hand throttle to open the tractor up all the way. Just adjust the length of that rod till the hand throttle pushes the injection rack against the stop.

Hopefully that is clear enough for you to fix.

Thanks for the good pics and explanation. I tried your recommendations and when I do, it does move the C plate closer to the throttle lever, just like you said. but what it does is keep the foot pedal too far away from the foot pedal return spring. (see the arrow pointing to raised gap). so the pedal return spring doesn't function like it should

Seeing how everything lines up, it seems like the pedal is supposed to sit flush in that return spring channel. when I do that, I am back to the original problem.

I'm thinking I might just use some vice grips to hold a temporary piece of metal in place to see how it reacts with a the metal rod moved a bit. I wanted that to be my last option.

I would not worry about the spring. It will sit in there when you push the throttle lever forward a bit. I would not try to bend it at all.

Does your hand throttle hit max rpm when in the full forward position? Can to take a picture of the C plate when you push the hand throttle forward to the max? I want to see where your hand throttle is hitting the C plate. Thanks.

 

[K5lwq]

Yes it does. I will take a picture of it tonight when I get back home.

 

[K5lwq]

Is this what you wanted?

I see that the linkage from the "C" plate to the foot pedal is orientated differently between your tractors. Not sure if that would make a difference.

Good point but I do not believe it matters. If the spring not engaging the petal is a concern for him he probably could tighten the nut on the foot petal and it would twist the spring up some. At least I think it would. Persanal it would not bother me because normally you would use the hand throttle to bring it up to 1200 or so RPMs anyway then use the foot petal. By then the spring would be engaged.

The issue was that while using the back hoe, the most i could get out of the engine was 1800 RPM (the 540 PTO RPM is listed at 2600 RPM). I ended up extending that linkage to push the C plate down and I tightened the throttle lever screw to give it some more friction to hold it. The RPMs would hold around 2100 which was enough to use the backhoe with good power/response. Thanks K5lwq for the quick replies.

On a side note, here is the mockup i had in my mind of how i would get the throttle lever to be in the right spot (either welding such a piece on or bending the lever until a similar spot:

That picture is before I extended out the linkage.
