Coulter Maintenance

A22350
A22350-UN-13OCT88

A - Cotter Pin

B - Slotted Nut

C - Coulter Blade

D - Face Seal

E - Hub Cap

The bearing has a face-type seal (D). Contact of seal against a machined surface retains grease and excludes dirt. If there is any play in bearing, do the following:

  • Clamp coulter blade (C) in vise.
  • Disassemble and clean.
  • Repack with John Deere TY6341 SD Polyurea grease or equivalent SAE multipurpose-type grease.
  • Tighten nut (B) until there is drag on bearing.

NOTE: Apply 1.3 N·m to 2.8 N·m (10 lb.-in. to 25 lb.-in.) of drag on bearing. This drag assures positive sealing. Replace cotter pin (A) into slotted nut to lock in position.

The bearings are packed with grease at the factory. Every 100 hours, inspect bearing and adjust if necessary. Every 200 hours, or before each planting season, disassemble bearing, clean, and repack as previously outlined. Do not use chassis lubricant in bearings.
