Hi guys, I have a 741 that has given me issues since day 1. Hydraulics function great but I lose almost all drive function when the machine warms up. I'm assuming the hydrostatic pumps need to be rebuilt but would appreciate any help or suggestions you have before I pull the pump apart. I plan on testing the charge pressure first then testing each hydrstatic pump output. I have already replaced the bronze filter numerous times and even ran without one for a short period and it still has the same symptoms. When I first start it, it runs and drives strong but after working for a little bit, it wont turn without me making a million k turns. I have experience rebuilding pumps on zero turns and I am pretty mechanically inclined so I'm not afraid of the job, just looking for any other tricks or tips before I pull this thing apart. thank you
