I wanted to move my post to this section out of Classified , more fitting here now . DrAllis , I have looked over all the manuals I have and cannot find GPM flow on this hyd. pump ! This is the (second) series pump and any information on it is HARD to locate . Do you know the GPM's on this two stage pump ??? I had it apart and very little difference between size of main gears & traction booster gear size .Prob doesnt take much to make big difference . Thanks
