Chamberlain B6755T Belt Drive Parts
Chamberlain B6755T Replacement Parts
The B6755T is a DC belt drive opener with a built-in camera, battery backup and a dual lens light pod, running on a square rail. This parts list covers all variants:
- B6755
- B6755T
- B6755TC
- B6755TCH
Camera not working, or light pod damaged? The camera and the light pod are separate parts — the 041-0041 camera with decorative cover at key 12, and the 041-0200-000 dual lens light pod at key 3. If only the trim ring is broken, the 041-0205-000 decorative ring at key 14 is the cheap fix.

| — | 041-0180-000 | Wire harness, camera and LED pod, dual lens — not shown on diagram |
The B6755T and B6753T are the same opener with different boards. The B6755T takes the 050DCTBFMC; the B6753T takes the 050DCTBMC. One letter apart and not interchangeable. Every other part on this page is shared between the two. Read the number printed on the board you are removing before ordering, and call (866) 965-5599 if you are unsure.
The motor at key 6 comes with a travel module, so you do not need both. If the door reverses at the wrong point or will not learn its travel, that is usually the travel module alone — a cheaper part and a quicker job. Beeping or slow running during a power cut is the 4228 battery, which is a consumable.
2. Rail Assembly Parts
First part of number below corresponds to diagram number above:
| Key | Part Number | Description |
|---|---|---|
| 1 | 041A5250 | Belt kit — 7 ft door |
| 1 | 041A5250-1 | Belt kit — 8 ft door |
| 1 | 041A5250-2 | Belt kit — 10 ft door |
| 2 | K144C0054M | Belt idler pulley |
| 3 | 004A1008 | Chain, #48, master link |
| 4 | 041A5665 | Rail kit, 7 ft |
| 5 | 041C5141-2 | Square rail trolley kit |
| 6 | 041D0598-1 | U bracket adapter |
| 7 | 041A6689 | Threaded shaft, D shape |

| — | 041A7276 | Trolley wear pads — not shown on diagram |
| — | K083A0011-1 | Lithium rail grease — not shown on diagram |
The belt is sized to your door height, not your rail — measure the door opening. A belt rarely fails on its own: check the idler pulley, trolley, tensioner and wear pads while the rail is apart. Re-grease with the lithium grease above; do not use general purpose spray lube on a square rail.
3. Installation Parts
First part of number below corresponds to diagram number above:
| Key | Part Number | Description |
|---|---|---|
| 1 | 041B0035B | Curved door arm |
| 2 | 041A5047-1 | Door bracket |

| — | 041-0365-000 | Sensor eyes and brackets — the complete set |
| — | 893MAX | Universal replacement remote |
The B6755T takes the 041A5047-3 square rail header bracket — the standard header brackets will not fit. If your sensor brackets are bent or missing as well as the eyes, the 041-0365-000 includes both and works out cheaper than buying them separately.
