Kioti Lk3054 hydraulics quitting intermittently

[double hunter]

LK3054 hydraulics quitting,,I was pulling my finish mower today and after about 3 hrs the hydraulics quit, Fel, power steering and lift all quit,,turned it off and got off to check for leaks or any thing obvious,,nothing, cranked it back up and worked for a few minutes and could tell it was going to quit,,drove it to the house and let it set a while, not long enuff to cool off and and its working again,,its new to me, I just changed the fluid as I had to replace the pto shift fork,,dont know when the filter was last changed but am going to change it tomorrow if I can find one,,any other suggestions, anybody have a cross reference for the filter,,will try NAPA in the morning

Changing the fluid and filter is a good idea. Even if it doesn't solve your issue, you will have a little more pease of mind.

Was it making any noise while trying to get it going? Also did the RPM have any affect?

I would probably say broken pump drive gear or shaft. Would pull the pump to check both.

Did the engin labour more than normal ? Check if the external controlevalve has a detent and if that lever was in working posision.
Like someone hang his foodparcel on that lever ?

Its metal mesh. Wash it out in kerosene

I pulled the filter off this morning and Ive never seen anything so bad,,about 1/2" La. gumbo mud settled in the bottom of the canister and the filter was horrible, drove 65 miles to my nearest dealer and they had one,,replaced it but have not had a chance to run it other than to just crank and check for leaks,,this should correct this

Tried the x-ref this morning and it only shows, air, fuel and oil

Hopefully that solves the issue. I was afraid it was going to be a cracked pump. Kioti had 3 different pumps for the 3054 depending on year.

They started with a 8GPM pump and later replaced it with a 10GPM version. This version was aluminum and would crack with heat. Many of these pumps were replaced under warranty to a cast version of the 10GPM pump.

From what I see, this pump was a good one. In fact, I upgraded my pump to this version and so far it has been great!
