My OEM timing belt number is discontinued: can you still supply it?
Direct answer: In most cases yes. A discontinued part number is a catalogue label, not a manufacturing limit. What actually defines the belt is the tooth profile, the pitch, the tooth count, the pitch length and the width. Once those are known, the belt can be built from a standard size or from an existing mould, even when the original supplier has stopped listing it.
How a discontinued number is converted
- Read the marking on the belt back. Most numbers combine a profile suffix (XL, L, H, XH, 3M, 5M, 8M, 14M, T5, T10, AT10) with a tooth count or pitch length, plus a width code.
- Confirm the profile by measuring pitch: the centre distance between two adjacent teeth identifies the family faster than any catalogue.
- Match on tooth count and pitch length, not on the brand name. Two belts with different numbers are often the same geometry.
- If the length is not a standard mould, discuss an open-end build cut to length, or the nearest standard length with a small centre-distance adjustment.
- Approve a dimension drawing before production for anything non-standard. That single step prevents most wrong-belt shipments.
What to send with the enquiry
| Information | Why it matters |
|---|---|
| The old number, plus any second number on the belt | Gives a starting point and often reveals the original profile family |
| Photo of the belt back and of the tooth side | Lets us read the marking and count teeth without shipping the sample |
| Tooth count and measured width | The two values that most often decide whether a standard build fits |
| Measured pitch length, or pulley diameters and centre distance | Fixes the length when the marking is worn off |
| Machine make, model and drive position | Helps confirm tension, speed and any cover or backing requirement |
GOODLY is an independent belt manufacturer. Brand names such as Gates, Continental, Bando or Mitsuboshi are mentioned only to describe compatibility. We are not affiliated with those companies and do not supply their products.
Send the old number and a photo
Email sales@goodlybelts.com with the belt marking, tooth count, width and a photo of both sides, or use the enquiry form. We will confirm the closest match, say whether a standard size fits, and quote the custom option if it does not.
