Measuring Your Belt

Check the markings first. Most belts have their size printed on the back, for example A24, SPZ1000 or 8PK1200. Type that code into the search bar to find the exact match.

Markings worn off? Measure across the top of the belt for the width, and its depth. For the length, wrap a piece of string round the belt, mark where it meets, then lay the string flat and measure it.

Timing or ribbed belt? Count the teeth or ribs, and measure the gap between them.

Questions

Is this a genuine OEM part?
No. It’s an Optibelt replacement made to the original specification. It carries Optibelt’s markings rather than the machine maker’s part number.

How do I check it’s the right belt?
Find the OE part number in your machine’s parts book, or on the old belt, and check it matches one in the table. Combines use a lot of belts, so check the position on the machine too.

How quickly will it arrive?
We ship across the UK by Royal Mail, or FedEx for express delivery, and we ship internationally too.

Not sure it’s the right one? Call 020 8138 2848 with your machine model and the OE part number and we’ll check it for you.
