are you referring to the Mega Flow system? There were three options, standard, Mego Flow ready, and those already set up as Mega Flow. Depending on which of the first two you might have, visiting a salvage yard would be the best choice. Get a shop manual.
Have an 8970 and TV140 with Mega Flow.
No. The Challenger track tractors had a somewhat different hydraulic arrangement than the Genesis tractors. It has the pump drive gearcase the same as a standard flow Genesis but has another pump mounted on the front of it to provide steering flow. The front of the steering pump has an auxilliary drive where the double gear pump that you would see on a Genesis is mounted.
21 pump for remotes/3pth
15 pump drive
14 steering pump
10 dual gear pump
