I recently purchased an lk3054 with kl128 and kb1550 backhoe. The hydraulics are noticably slower now that the weather is warm (60's) vs sub zero when i bought it. The stabilizers now have to think about picking up the rear of the tractor and two functions at once are now out of the question. I am planning on changing the fluid as it has a self contained resivoir and pump, but i cant find the fluid capacity anywhere, or what fluid i should be using in it

Thank you, but now for the next question. Now that I know what type of fluid it takes, someone has regular hydraulic oil in it (based on the smell) do i meed to flush the system or is draining it enough to get the wrong oil out

I would retract what cylinders could be retracted, drain and refill. The little amount left will dilute with the oil....

Hi, new to this forum. First time owner and I have a related question.
I have a Kioti LK 2554 with a KB 1440 self contained pump and tank. My manual shows fluid to be 10w40 API SD rated engine oil. I can’t find it here and would be grateful for a link to locate this or an acceptable replacement. Not trying to go cheap, I would like a quality oil.
thanks, Cashtalksvince.

I use Amsoil synthetic 10w40 in most for my equipment (gas/diesel) and it should be excellent for your application. The API ratings are backwards compatible (SD is obsolete)so meets/exceeds your specs. Shipped right to my door easy peasy... Link below.

Thanks for the prompt and informative response. I’m considering my options now.

The link on the first post has the service manual for the 2020+ 15 series, which includes the 4815.
