Linear HAE00047 Helical & Worm Gear Kit – LSO, LDO & LCO Operators

The Linear HAE00047 Helical & Worm Gear Kit is a genuine replacement gear set designed for compatible Linear LSO, LDO, and LCO residential garage door openers.

The kit replaces worn internal drive gears that transfer power from the operator motor to the drive system. Worn or stripped gears can prevent the opener from properly moving the door even though the motor may still run.

Common Signs of Worn Operator Gears

Replacement may be required when:

• The opener motor runs but the door does not move

• Grinding or unusual mechanical noise is heard from the operator

• The opener starts but cannot properly drive the door

• Gear teeth are visibly worn, damaged, or stripped

• Internal gear debris is found inside the operator housing

These symptoms can also be caused by other mechanical or electrical problems, so proper diagnosis is recommended before replacing the gear assembly.

Important Before Replacing the Gears

A stripped gear can sometimes be the result of excessive resistance elsewhere in the garage door system.

Before installing a replacement gear set, inspect the door for proper balance and check the springs, rollers, track, bearings, and other moving components. Replacing the gears without correcting an underlying door problem can result in premature wear of the new components.

Installation

Disconnect electrical power to the garage door opener before servicing internal components.

Garage door operators contain moving mechanical components and electrical systems. Professional installation by a qualified garage door technician is recommended.
