Belt-Drive Opener Repair: what shapes the quote

No. The belt is meant to run clean and dry; oils and sprays soften the rubber and gather grit in the teeth, which wears the sprocket. Lubricant belongs on the door instead: hinges, rollers and springs get a garage-door lubricant once a year. The gear inside the motor head takes a light grease when it is serviced, and that is the technician's job.

Access to the rail

Shelving, a car lift or a loft beside the rail, or a garage that is full on the day, mean more careful handling along the belt's length, and the technician allows for it once the space is seen.

Height of the ceiling

Where the operator hangs under a tall or vaulted ceiling, the sprocket and idler are reached from taller ladders and the work at the head takes longer.

Gear and sprocket kit

Shavings on the motor head mean the drive gear is stripping. Replacing the gear-and-sprocket set means opening the head unit, which is more time and a more substantial part than belt work alone.
