Chamberlain B4655T Belt Drive Parts
Chamberlain B4655T Replacement Parts
The B4655T is a DC belt drive opener with a built-in camera, running on a square rail. Its head unit carries camera and light pod parts the non-camera B-series openers do not, and its end panels are camera-specific. This parts list covers all variants:
- B4655
- B4655T
- B4655ST
- B4655STCH
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 041-0201-000 single lens light pod at key 3. If only the trim ring is broken, the 041-0205-000 decorative ring is the cheap fix.
1. Garage Door Opener Repair Parts
First part of number below corresponds to diagram number above:
| Key | Part Number | Description |
|---|---|---|
| 1 | 041C1751 | Belt cap and sprocket kit |
| 2 | 041-0198-000 | End panel, no battery access |
| 3 | 041-0201-000 | Light pod kit, single lens, camera model |
| 4 | 041D0277-2 | Transformer, Wi-Fi non-battery backup |
| 5 | 041-0204-000 | Control door panel |
| 6 | 041-0236-000 | Motor with travel module, DC |
| 7 | 041-0197-000 | End panel, no lock |
| 8 | 050DCTBFMC | Logic board, Bluetooth enabled |
| 9 | 041D8071-4 | Travel module kit, universal DC |
| 10 | 041B4245-1 | AC power cord, 6 ft |
| 11 | 041A3150 | Terminal block |
| 12 | 041-0041 | Camera with decorative cover |
| — | 041-0205-000 | Decorative ring, camera — not shown on diagram |
| — | 041-0181-000 | Wire harness, camera and LED pod, single lens — not shown on diagram |
Careful with the logic board — the camera models split two ways. The B4655T takes the 050DCTBFMC; the B4643T takes the 050DCTBMC. One letter apart and not interchangeable. The transformer is the 041D0277-2, the non-battery-backup version, and the end panels are camera-specific — panels from the non-camera B-series will not fit. Read the numbers off the parts you are removing, 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.
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 |
| 8 | 041B4103 | Belt tensioner kit |
| — | 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 |
| 3 | 041A2828 | Emergency manual release rope |
| 4 | 041A5047-3 | Header bracket — square rail |
| 5 | K029B0137 | Remote control visor clip |
| 6 | 041-0155-000 | Safety sensor bracket kit |
| 7 | 041-0136 | Safety sensor kit |
| 8 | 4178B0034B | Straight door arm |
| 9 | 041B4494-1 | White and red bell wire |
| 10 | K010A0020 | 3V CR2032 lithium battery |
| 11 | K012B0776 | Hanging bracket kit |
| — | 041A7920-2 | Hardware kit — not shown on diagram |
| — | 4228 | Battery, 12V — not shown on diagram |
| — | 041-0365-000 | Sensor eyes and brackets — the complete set |
| — | 893MAX | Universal replacement remote |
The B4655T 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.
