So I have a 1968 loader 150 with the Drott 4n1. I'm having trouble with what I believe is the hydraulic system on the transmission side. I'll do my best to describe what it is as I have been unsuccessful at finding the part in the manuels that I have. When looking at the machine from the front, the part in question is on the right hand side at the very rear of the machine. Behind the pressure filter which is located next to the range selector valve is a cover with what looks like a spring with 4 3/4" or 7/8" retainer bolts around 18" long. The problem I'm having is when I go to turn the engine over, hydraulic fluid is pouring out from something at the base of the spring. I haven't been able to identify what it is or exactly where it's coming from. I can't get the cover off of the machine yet. We built a homemade Rops and its bolted to the top of this cover. I know it's a shot in the dark but any help is greatly appreciated. I'll post pictures tomorrow when I get a chance.
