Liftmaster 041A7314 - Chain Kit, #48x73
The LiftMaster 041A7314 is a #48x73 chain replacement kit used on select Chamberlain chain drive garage door openers and related LiftMaster applications when the replacement parts diagram calls for this exact chain. In service, a chain kit is often replaced when the chain has stretched beyond adjustment, is rusted, has damaged links, or will not stay properly tensioned on the sprocket and trolley system. The #48x73 reference is important because chain size and length must match the rail and opener configuration. A chain that is too long, too short, or the wrong pitch can cause noise, poor travel, sprocket wear, and unsafe door operation. This part is not a universal 7 ft chain-and-cable assembly and should not be confused with 041A1340 chain extension, 041A3473 chain-and-cable kit, 041D3484, 041C2735, or sprocket-only kits.

Technician Note
Measure and identify the original chain by the opener parts diagram, not by guessing from the rail length. Similar #48 chain kits can have different lengths, master link requirements, and rail applications.
Before Ordering Checklist
- Confirm the original chain part number is 041A7314 or 41A7314
- Verify the opener is a compatible chain drive model
- Check rail type, chain pitch, and chain length requirement
- Inspect the sprocket and trolley before installing the new chain
- Correct door balance or binding issues before re-tensioning the chain
Professional Advisory
A chain drive opener should not be used if the chain is jumping, binding, or dragging. Disconnect power before service and have a qualified technician inspect the door and rail assembly if the chain failure was caused by door resistance.
Product Questions and Answers
What does #48x73 mean on this chain kit?
It identifies the chain size and length reference for this replacement chain. The opener parts diagram should confirm that 041A7314 is the correct chain.
Will 041A7314 fit belt drive openers?
No. This is a chain kit and should not be used on belt drive, screw drive, or wall mount systems unless a parts diagram specifically calls for it.
Is 041A7314 the same as 41A7314?
Yes. 41A7314 is commonly used as a shorter reference for LiftMaster 041A7314.
Should I replace the sprocket with the chain?
Inspect the sprocket teeth, shaft, and set screws. A worn sprocket can damage a new chain and cause repeated slipping.
Can I shorten or modify this chain?
Do not modify the chain unless the opener manual specifically allows it. Use the correct replacement chain for the rail assembly.
