Hydraulic pumps

[Dieselray]

Hi
I have a KX 027 grey market excavator. Having a slight problem steering to right. Lot slower then left side.
Have changed inlet and outlet filters and hyd oil. Overhauled final drives.
Could someone tell me which hydraulic pump supplies oil to controls. This machine has three pumps
running off flywheel and one off rear of injector pump.Need somewhere to start checking pressures.
Many thanks
Ray

Welcome to the forum.

I know little about those excavators, and in the absence of any other info from members here I'd suggest that you get a workshop service manual from somewhere (I had a quick Google and they don't seem commonly available, not available on Kubotabooks.com). If none found for your model then look for manuals for similar models. The benefits of a WSM usually far outweigh the cost. If you don't have an operator's manual, get one too.
