Remove screw and nut from back of mixer head to release the silver name band. Remove the exposed four cross head screws, (two each side), and lift off the motor and gear cover. Wipe excess grease from gear wheels to expose the retaining ring clip at top of vertical gear shaft. Using small nose circlip pliers, remove retaining ring and bevel gear wheel to expose shaft pin and worm gear. Support the shaft from below and remove pin. Lift off worn worm gear wheel allowing shaft to drop down. The horizontal worm gear shaft can now be lifted out taking care to keep assembled. Carefully clean old grease from all gears and from the gear housing, (note that broken pieces of the old worm gear are in the old grease. Repack housing with fresh high performance grease recommended for worm drives. Cover new and reuseable gears with grease. Reverse the process to reassemble the unit.
