3B vs. 3Bii water pump pulley

[Eurasiaoverland]

Does anyone know the difference between a 3B and 3Bii water pump pulley? The type for a fan clutch.

Does anyone have a 3Bii water pump pulley for a fan clutch application they could measure?

I know the water pumps are different, and the part numbers are different, so they are not the same.

Thanks

Older 3B has 6 mm bolts and later 3B and 3B-II has 8 mm. The pulley offset is different too.

Good to know, thanks. I have a 2 belt Megacruiser pulley, so I sould be able to work out how high a 3Bii pulley is.

I know that the bolt patten and spacing are the same on the late 3B and 3Bii as both can use the same fan clutch (16210-58012).

So just the height and possibly diameter that could be different.
