Sounds like you dropped some large coin to get your machine sorted out, so I suppose that means you intend to keep it for a spell and try to work some of your money back out of it. Depending on the year model, the T190 is either a G series or K series machine. If the gear pump (also acts as charge pump for the hydrostat pumps) had a problem that it wasn't building enough pressure then you should have been hearing three short beeps from the alarm. If you ever hear that machine make three shorts beeps from the alarm, don't touch nothing else, don't shut it down, instead, right then, push and hold down the headlight button, this will bring up the active code that prompted the alarm in the hour meter display. If you had a bad gear pump causing low charge pressure, you should have got a code on that and would have a better idea of what's causing the problem.
I suggest you do not work your machine until you find what the problem is. If it is the break the debris off the linings could go through the hydraulic system.
