I have what I believe is a 610 Allis Chalmers forklift. It has a D15 Series 2 engine (160 cu. in.) When I start the forklift the power steering is really hard to turn. It takes quite a while of warm up before it works properly. The forks lift right away. Do you have any suggestions? Am I getting air into the system when it sits overnight?

In January of 2025 you said: "we do not suspect the pump". Back then, I told you I thought it was the pump. Yesterday, I again told you I thought the pump was losing its prime when it sits. I am visualizing a single TANDEM (twin) pump that has a problem in the power steering section and it may be at the driveshaft end of the pump, pulling air thru the shaft seal.
