The D series hoe and loader uses the main hyd system pump for steering and has a relief valve in line up near the floorboard to control system pressure. it is not supplied like earlier models with a gear pump driven from the Cam gear. It is a different animal and maybe you should try to get a service manual for a D, one from and E should work also, Just seems like yolu are throwing parts at it without a diagnosis and that gets costly. mEl This post was edited by mEl at 16:36:04 06/21/11.
