Re: **John Deere Walker Repair/Maintenance Tips Th
Thats a BIG 10-4 on the walker bearings. my 50 only lasted about 1200 hrs. I never had a problem with these bearings on my older 9600. Come to find out I took these deere new bearings destined for the walkers to a bearing house near by and they arent what they seem to be. I told the guy when I walked in that I have a pre engineered life problem with bearings,, he laughed, but by the end of our meeting he was convinvced. Some quick research exposed that deere is using C-4 tolerence or clearence in that particular bearing, Normal clearence of bearings is a C-0. All the other walker crank bearings are a C-0, except this one behind the box. ALSO, All these bearings as most on these machines have only single lip seals or shields on the bearings and nothing special for grease. I am retrofitting all these bearings to a C-0 clearence, metal shielded, tripple lip, greaseable bearing with wider inner race for better handling of eratic, radial loads. The buy at the bearing house could not believe that all of the bearings I brought to him from many parts of the machine all had single lip seals and were not greaseable to purge out contaminants. Im also going to wood blocks on the walkers to get away from pesky alloys and three tubes a day greasing interval.
