Technician Note
Wear pads are only one part of the trolley system. If the trolley body, rail, chain, or belt hardware is damaged, replacing only the pads may not restore smooth operation.
Before Ordering
- Confirm the rail assembly uses the square rail style
- Match the parts diagram to 41A7276, 041A7276, or 183A163
- Inspect the trolley body for cracks or heavy wear
- Check rail alignment and hardware before reassembly
- Confirm all four pads are needed for the repair
Professional Advisory
Do not operate the opener if the trolley is binding or the door is difficult to move by hand. A door balance or rail problem can damage new trolley components quickly.
