I have a 80s caterpillar 416 4x4 backhoe with a weak lift on the backhoe. I checked the resolvers and there are 2 o rings on each one.The cylinders have been rebuilt. Please help i am at a loss where do I go from here
Is it only the boom that's weak? What are the pressures on every function when stalled. Does stall pressure change between low and high idle?
