Drive belt part no's

[feef]

I've got a 6PK1263 drive belt on my MX5, driving the power steering pump and supercharger.

I've received a 17% reduction pulley for the supercharger to get more boost so will need a shorter belt. I'm sure I had a link to a page that deciphered drive belt part numbers into number of ribs, length etc. but I can't find it.

Anyone got any info on how the part numbers relate to belt code so I can work out the correct part number I need?

6PK1263 = 6 ribs, PK is the rib type, 1263 is the length in mm

Thanks.

I came back to say I'd worked it out as well.

Shorter belt on order. Will pick it up later today.
