Things have change from the early models. The GC2300/2400 had a breather tube on the hydro as well. I can not find it on any diagragms for it the GC1705/1723. The plug for the hydro fill was the same style as the fill plug on the front axle. The GC1705 was the first model that i know of that had problems with oil coming out of the plug, or blowing out the sight level gauge. The tube extension (#19 pipe coupler) in the picture may be for the backhoe equipped models.Never mind, misinterpreted a previous picture... Guess my comprehension skills are fading with age...
