Stuart D10 has mechanical lubricator to lubricate the cylinders and slide valves with Mobil 600 W Cylinder Oil. The mechanical lubricator is connected to the connecting rod for feeding pump.The reduction gear ratio is 3:1. Also no problem to lubricate the cylinders with reduction gear since it's enough oil in the cylinders. I learned out the mechanical lubricator with direct connected to excenter connecting rod will give too much oil to the cylinders. With reduction gear will give long duration between refilling of the cylinder oil into the mechanical lubricator. There is no sign of wear of piston/cylinder and slide valve. The feeding pump is connected to reduction gear and has the bypass valve to control the water level in the boiler. Bypass valve should be connected to servo and is controlled by automatic boiler water level control system. Gas attenuator detects the pressure in the boiler on one side of the valve and when the pressure reaches a preset level, it turns the gas flame down, the other end of the valve, until the pressure reaches a lower level and so starts to feed more gas to the burner. This old gas attenuator is replaced with other gas attenuator + gas stop valve.
