190 XT diesel throw-out bearing,need help

the last 2 times I've used my 190 XT, It's done a little growling when my foot is on the clutch when I first start it. After it's warmed up, it seems to be OK, which I find to be kind of peculiar. I would assume that the throw-out bearing is on its way out. There is not a grease zerk somewhere for the throw-out bearing that I'm overlooking is there? Or is there something else that could be wrong that I'm overlooking? I am using the tractor on a round baler, and seldomly even use the foot clutch, cause I use the PD all of the time, so the throw-out bearing is not being overly taxed at all. Any help, ideas? TIA   Darrel

Sounds like throwout brg failure in the making. Many/most times the failure is due to the pedal "freeplay" has gone to zero and the brg runs all the time. Two inches minimum pedal freeplay must be maintained at all times (4 inches is better yet)........takes a split to fix it and it will eventually eat thru the clutch pressure plate fingers when it completely fails. You can look at it from underneath the bellhousing by removing the rectangle cover plate.
