| Need some help on a 1994 John Deere 6400 MFWD with 640 loader with Power Quad. Was using it and it locked up and would not move. let it sit until it was cooled down and it moves again but has a vibration. Took it to the closet Deere dealer who is 200 miles away and they drained the oil and checked the screen. No metal or debris on the screen and cut open the filter and nothing in it. They are going to have to split it and want $5,000 just to look at it. I am considering bringing it home and working on it this fall my self. I have read at least 2 post on the web about pinion bearings failing? Anyone have any information about these or how big of a job to repair it. Wondering if the cab must come off rather than tipping it. It looks as if the pinion is in the range case between the trans and rear axle. | |
