I replaced the pintle shaft seals and I am Now getting very little air and foam in the tank. I think this is normal air that needs to get bled out now, and preliminary testing had the hydraulics working nice and smooth. Amazing. Now I need to get the rest of the machine back together and put it to work and see how it goes. The service manager at my dealer mentioned that these were a common source of air leaks on these old machines, and since they point up, you don't see any oil seepage. Bobcat only sells entire seal kits--which are $260 for each pump!! Luckily, I was able to take the part number of the old shaft seal and source a couple new ones on eBay for $20 bucks each. Thanks to everyone for all the suggestions!</p></blockquote><p></p>
