This all started because the housing of the hydraulic pump is aluminum and I could not keep the bolts from loosening up. Thinking I had a bad seal I pulled it apart - only to find that the company had sent the wrong kit. This happened twice. On second teardown I tore one of the e seals. Here I sit. If this happens to you - put an expensive Timesert in the first time you take the pump out. Lock tight won't prevent the aluminum threads from stretching over time.

Interesting. I have the same year as yours, but almost double the hours, and would like some more info on which bolts that you are talking about so that I can check those bolts on my CK30. Can you add a picture of these bolts or describe in detail which bolts caused the issue for you? Sorry to bother you and hopefully you've got it fixed soon, Dutchy
My pump is at a hydraulic shop for the last few months as they try to find parts or build new pump with NA parts. There are four long metric bolts clamping the pump case together. Two would stretch the aluminum threads in the pump case, possibly as a result of heat expansion and subsequent cooling. If you catch it quickly enough you can insert timeserts into the aluminum or have a hydraulic shop build a new head end for the pump out of steel.

Where are these 4 bolts that you speak of? Are they external so that they can be checked? Has Kioti offered to help you out in any way? Thanks, Dutchy
The four bolts are on the outer flanges of the pump. They can be accessed with some difficulty behind the right loader bracket, below the dash/fuel tank.
