I am likely replacing the drive motor on a 2005 Bobcat T190. I looked online a fair amount and was unable to tell what the difference was between the 4 port and 5 port drive motors. When I had the track off, I only saw 4 hoses going to the motor (2 pressure lines, case drain, and brake release), but when I looked up the part on Bobcat's parts website with the serial number, the part number is for a 5 port. I looked in the service manual and it says about a 5th hose going to the back of the motor that is the brake power assist hose. Is this the 5th port? I just want to make sure I order the right one. Thanks in advance, Ross
