Quoting Removed, click Modern View to see An N is quite capable of running a lot of implements that require a hydraulic system of this sort and Ford provided similar setups for the NAA and 600 sereis tractors. The internal sump capacity is sufficient for this size pump with a couple caveats. First the 12 GPM pump rating is maximum output at 2000 engine RPM The flow rate is proportional to engine speed - e.g 8 GPM @ 1500 RPM, 6 GPM @ 1000 RPM, etc. You also need to consider the duty cycle of the hydraulic loads you are running. For example you wouldn't want to try and run something like a rotary broom tpowered by an 8 GPM hydraulic motor. The motor onteh broom has a nearly 100% fully loaded duty cycle and with that small a reservoir the oil would overheat from the constant high pressures. But you can run something like a loader that actually has higher peak pressure flow requirements but with very intermittent duty/load cycles that give the oil a chance to cool down between cycles. The valve in the pictures controls two DA cylinders and requires 4 bidirectional couplers. So the coupler count is not as much about volume as it is function. Those are 3/8" couplers good for about 6-8 GPM each which is overkill for the customer's current application which is a front snow plow with power lift and angle. But because he wanted the flexibilty to run a small loader he balked at a smaller pump and 1/4" couplers. In fact he initially wanted four more front couplers to go with the rear ones but I talked him down off that ledge - at least for the time being ;-) Next N-series hydraulic system on my schedule is a 16 GPM pump for a guy with a loader/backhoe. He will be using his existing 5 gallon external reservoir to up the overall system oil capacity to 10 gallons. TOH [Reply]   [No Email]
