Hello Everyone
I have the 2005 B Series I was having the no drive power and would loose bucket and lift power. Replaced front drive And All power cam back. however had no 2 speed and yes the two speed is turned on. So talking to the people I purchased Drive from said could be other drive and Bobcat service that the same . So put a Drive in rear same problem .Checking Charge Pressure I have 350PSI which in Spec. so in low range on jacks the tires spin 45 to 46 In two speed front turns 65 and rear turns 36. this was from dealer when I brought in to Calibrate drive motors and updates on the machine. So Bobcat said one on the drives must be bad. So loaded Machine took took to place that I purchased the drives from luckily there where 2 hours away they said brimng out and let use look at it. So they pulled drives and tested and checked out fine. put bench tested motor in rear and put the one from rear into the front same results. So then they where thinking maybe a collapsed hose from Pilot valve to the speed on the motors.. They made a hose from Pilot valve to rear motor with a gauge on and they plugged the front hose. motor would show 350psi in low range and when two speed on 400 psi but 2 speed would not kick in. So they added a porta power and when they pumped 500psi the 2 speed took off. they are baffled. we have confirmed both drives are good . front seems like its going into 2 speed. Swapped Speed sensors front to back same results. Any one have any Ideas. they even tried weaker 2 speed valve springs which did give a little more speed. but if any slight incline drops to 10.5 mph. Going down hill it will go like crazy but if flat road only 10.5. Any Ideas?
