I recently purchased a 2003 NH TC33D. The differential lock pedal cannot be pressed down because the rod from the transmission that it is linked to appears to be stuck. My guess is that it has never been used in its 9 years of existence. I have tried dousing the rod where it comes out of the transmission with penetrating oil, pressing with all my 210 lbs on the pedal, and tapping the pedal with a hammer (but not too hard for fear of bending the linkage), and no luck. Anyone know a technique or have a suggestion of what I could try? Is the rod supposed to be able to rotate? i.e. would it cause damage if I clamped onto it with a vise-grip and tried to rotate it? What about tapping the rod inward?
