Coulter MaintenanceThe anti-friction bearing has a face-type seal (D). The contact of the seal against a machined surface retains grease and excludes dirt. Unless the bearing is in proper adjustment, the seal is ineffective. If there is any looseness in the bearing, clamp coulter blade (C) in vise, disassemble, clean and repack with John Deere Multi-Purpose Lubricant or an equivalent SAE multipurpose-type grease. Tighten nut (B) until there is drag on the bearing. NOTE: Apply 1.3 to 2.8 N·m(10 to 25 lb-in) of drag on the bearing. This drag assures positive sealing. Be sure to replace the cotter pin (A) in the slotted nut to lock the nut in position. These anti-friction bearings are packed with grease at the factory. Every 100 hours, inspect the bearing and adjust it if necessary. Every 200 hours, or before each planting season, whichever comes first, disassemble the bearing, clean, and repack it as outlined above. Do not use chassis lubricant in anti-friction bearings. |
