Hello
My 185 has developed a new issue this year after using it for snow removal. I began to see hydraulic fluid on the snow, and immediately took it into the shop and looked it over. The entire top of the transmission was covered in fluid. I cleaned it up with brake kleen, checked the return hose clamp was tight, and went back to work keeping an eye on things through the window in the sheet metal where the shift level come up. I noticed that while running at full throttle while operating the 3pt, the fluid is coming out around the shift boot.At low to mid throttle this does not happen. The boot is hardened from age, but i'm wondering if something else is causing the fluid to push up past it, or if i simply need a new boot. I want to check the transmission vent, but was not able to find it yet, and make sure its not clogged. Any pointers on other things to check, and the location of the vent would be much appreciated.
Thank you all in advance.
 
Unless the 185 shifter is different than the 154, there is no vent, and there is no boot, just the metal cup. When mine did that
it was the metal part the return hose goes in cracked, I assume form years of use and vibrations. I cant think of any reason it
would be coming from under the cup unless its overfull.
 
I will check the fluid level this evening, i may have put too much in when servicing it last year. When adding fluid, should the level be set/checked with the hydraulic cylinders extended, or retracted? It has a belly lift and rear 3 point.
Thanks guys.
 
It only holds like 3 1/2 pints, but I think the last time I serviced mine I had the deck down, and filled to the fill plug. I would assume if that wasnt enough, IH would have put the plug higher up the rear cover.
