3B alternator belt - what size?

[LHD_Kid]

Having searched the forum (on my cr@ppy phone) for a couple of hours, I am unable to confirm for sure...

What size is the 3B alternator v-belt? Is it 10 x 858?

Thanks!

Seems to be 054903137 which is 11.2 x 866 mm

Thanks Dave - I did look on 7zap too... but finding it a bit confusing....

If you check the diagram which most closely resembles the 3B (middle right), it labels D as power steering pump and B as alternator (which makes sense)

This would make the belt number 11, but they label this as power steering belt..

Cross referencing on the analogues for #9, it brings up around 7 sizes

Including:
10 x 875
11.2 x 866

I know I'm easily confused...

Now that you mention is B and D are either mixed up or 9 and 11 are mixed up. Can't blame 7Zap though. ETKA apparently had the same problem.
