My case 1835c diesel has lost movement to the bucket. When i start it after a day of not running, there is no response to wheels, bucket or arms. After a couple minutes i slowly start getting a response from the wheels. Little by little the wheels slowly start moving intill i have full response from wheels. But still nothing from bucket or arms. It almost seems like it takes a while for the preasure to build up enough to move the wheels, but not quite enough to move anything else. Im thinking my pump is going out. Or can it be something else? Maybe something clogged???
