I don't know if that poppet is for cold weather, I know where the one in on mt NH and its function is to stop the oil flow in the return line until the pressure builds to the charge pressure level. Forget what they call it. Could you take a picture of the Bobcat one and describe the location? Would be good to know where it is and what it looks like.heatpumpproducts: slightly late reply, but the seal for the pintle levers is a simple lip seal, you will need to remove the centering plate, then the alloy arm that bolts to the yoke. You must fully remove this bolt to enable it to slide off the shaft. You will need to remove all 4 bolts on the cover on the top of the pump that hold the seal. You will need to replace the shaft seal and you will also need to replace the square O ring that seals the plate. It can all be done without disturbing the inside of the pump.
Slightly off topic, but here is a picture of the gland nut from the tilt ram, i had a little trouble removing it!!! ended up needing to use an air chisel and oxy torch. I was lucky enough to still have a piece of alloy that i was able to machine a new one out of, worked out pretty well. Some how the thread picked up and it refused to move. I had a 10' bar holding the body of the ram, i then used a LARGE pipe wrench with a 6' pipe and it still refused to move much more than a few mm every try. Out came the air chisel and it would move slightly every try.

Did the threads all "roll up" on that gland nut , tight all the way, or was it just tht hard to break loose. I don't like the way they have the undersized 2 pin hole system to remove these. I made a tool for the ones on my old hoe and it was hopeless. Ended up with a big pipewrench and scared the aluminum nut all up. But nothing like that. I need to fix the brake on my lathe so I can thread, incase I need to do that someday.
