LiftMaster 041C4220A-6P Chain-Drive Gear and Sprocket Kits — Six-Pack

The LiftMaster 41C4220A-6P supplier offer is a six-pack of the 041C4220A chain-drive gear and sprocket repair kit. It is intended for servicing multiple compatible openers or keeping the specified repair kits on hand. LiftMaster identifies the individual kit for selected LiftMaster and Chamberlain chain-drive openers manufactured after 1993, with exact model confirmation required. Six-pack quantity does not broaden compatibility: this is not a universal repair for belt-drive, screw-drive, wall-mount or every chain-drive opener.

Compatibility — Models, Versions and Exclusions

Confirm Each Opener Before Using a Stock Repair Kit

Bulk purchasing is useful only when each planned repair uses the same approved part. Record the model number for every opener being serviced and check its diagram. A chain-drive label or similar housing does not prove that the shaft, bearing arrangement and internal gear set match. Keep the base kit number attached to each stored package to avoid mixing it with other drive kits.

A stripped gear or worn sprocket can be associated with excessive door load, poor chain adjustment or wear elsewhere in the drive. Have the technician inspect the door balance and the opener before replacement. The new gears should not be used to force a binding door. A six-pack is six repair kits, not permission to omit diagnosis or post-repair testing on any of the individual doors.

Specifications and Product Identification

Before Ordering

• Verify 041C4220A in each opener’s parts documentation.
• Confirm that the order is for six kits rather than one.
• Have door balance, chain condition and related drive components inspected.
• Check current six-pack availability and contents before planning multiple service jobs.

Package Contents and Separate Requirements

The supplier identifies six kits. LiftMaster describes the individual 041C4220A kit with the helical gear/top assembly, worm gear, wear bushings, grease and repair hardware. Confirm the actual bulk package before ordering. A complete rail, trolley, chain, motor or logic board is not promised as included, and the individual-kit inventory should be checked against the supplied revision.

Safety Warnings — Read Before Installation or Service

• WARNING: An unbalanced garage door and moving opener drive can cause serious injury. Gear replacement requires a trained door-systems technician.
• Disconnect opener power and follow the manufacturer’s door-securing procedure before service. Do not release an unstable door.
• Do not adjust springs or cables without appropriate training, and do not increase opener force to overcome a binding door.
• Restore covers and verify travel, reversal and photo-eye operation on every repaired opener before normal use.

Frequently Asked Questions

How many kits are in this offer?

The supplier identifies a six-pack. Confirm the current package if ordering for multiple repairs.

Can I buy the individual kit instead?

The store has a separate 041C4220A listing. Check its offered quantity and suitability for your repair.

Will it fit every opener made after 1993?

No. LiftMaster’s date guidance is only one condition; the exact model’s service diagram must identify the kit.

Does a new gear kit fix a heavy or sticking door?

No. The door and drive need diagnosis and any underlying mechanical faults must be corrected.
