Function of the Feed Roller Sprocket

The 285928-00 Sprocket is designed to:

• Drive the planer feed rollers through the chain system
• Maintain synchronized feed roller rotation
• Provide smooth material feeding through the cutter head
• Help ensure consistent feed speed
• Restore proper drive system performance
• Maintain factory operating characteristics

Using a genuine OEM replacement sprocket helps prevent chain skipping and ensures reliable material feeding during planing operations.

Common Signs Replacement Is Needed

Replace the feed roller sprocket if you notice:

• Worn or chipped sprocket teeth
• Chain skipping during operation
• Broken or cracked sprocket
• Sheared keyway or damaged bore
• Inconsistent feed roller movement
• Material feeding unevenly through the planer

A worn or damaged sprocket can cause improper feed roller operation, inconsistent material feeding, and reduced planing performance.

Installation & Service Notes

Disconnect the planer from the power source before performing any maintenance.

Remove the planer side cover to access the feed roller drive system. Carefully remove the drive chain and retaining hardware, then remove the worn 285928-00 Feed Roller Sprocket from its shaft. Inspect the drive chain, key, retaining rings, bushings, and adjacent sprockets for wear before installing the replacement sprocket. Ensure the key is properly seated in the shaft keyway and verify the sprocket is installed in the same orientation as the original. Reinstall the chain, confirm proper alignment and tension, and rotate the drive system by hand before operating the planer. If the chain shows excessive wear or slack, replacement is recommended at the same time.

Important: Always verify your planer model and original part number before ordering. After installation, confirm that all feed rollers rotate smoothly and the drive chain remains properly aligned before returning the planer to service.

Maintenance Recommendations

• Keep the drive chain properly lubricated as specified by the manufacturer.
• Inspect sprocket teeth periodically for wear or damage.
• Replace worn chains before they damage new sprockets.
• Keep the drive compartment free of sawdust and debris.
• Avoid overloading the planer with excessively deep cuts.
• Use genuine OEM replacement parts to maintain factory fit, smooth feed roller operation, and long-term planer performance.
