kioti DK40SEH loss of hydraulic power arms won't go up much

blurry · May 12, 2018

Hi guys. I'm in a pinch and could use some help. Just bought a waterfront lot and it needs to be cleaned up stat (long story). I'm on a DK40SEH.

symptoms: drives fine on flat surface. occasional loss of power which I believe is related to incline. loader arms go up a couple feet and stop - I can hear a pump running but no movement. I tried to lift the front wheels with the grapple and there appears to be very little power (went down and didn't even try to lift the front wheels). I added about a gallon of fluid through the red vent tube (removed first

) - dipstick is reading at the high end of the tick marks. checking with the engine off and fluid warm.

I have a small leak on the aux hydraulic lines and which is how the level got low.

any ideas what I should be doing here? I'm feeling rather out of luck right now

thanks!

Your rear remotes accidentally engaged?

remote is not engaged, checked the remotes (connected to grapple) and grapple is moving though slower than I thought it did.

I did notice that if I put the loader down (not in float) and curl it to lift the front end it is extending the loader lift arms which it shouldn't - then if I try to lift the loader you have to hold it for a while before the arms raise - then they stop really low like before.

Try unplugging and then plug in all 4 couplers beneath the right step at the control valve. Make sure you get them seated back. Give that a try. Do this with the engine off of course.

for anyone that has an issue like this - visually I couldn't tell the line was loose - I checked because @k0ua asked to unplug and re-connect them.

man, you guys and gals are great!
