Garage door cables do not work alone. On torsion spring systems, each cable wraps around a cable drum at the end of the spring shaft. On extension spring systems, cables run over pulleys mounted near the horizontal tracks. When drums or pulleys wear out, the cables lose their path, and the door can hang crooked or stop moving altogether.
Drum and Pulley Repair by GDS-RepairParkRidgeIL
Our technicians look at the whole lifting system, not just the cable that came loose. A cable that keeps slipping off usually points to a deeper problem with a drum, pulley or the door's balance.
Cable drums
Drums have grooves that guide the cable as it winds. Over time, set screws can loosen and grooves can wear down. We check drum position, tighten or replace set screws, and install new drums when the grooves are damaged.
Pulleys
Extension spring pulleys use bearings that can rust, crack or seize. A worn pulley chews through cables quickly. We replace pulleys and their hardware so the cable runs smoothly.
Matching cables and balance
Both cables must be the same length and carry equal tension. After any drum or pulley work, we re-tension the cables and confirm the door is level and balanced.
