The precision 6262 and 6266 have a 6+6 and 7+7 blade Version of the compression wheel, we have both replacements wheels. Both 6+6 and 7+7 blade compressor wheels measure 62.24 x 82mm, but the 7+7 blade compressor wheel has an extended tip exducer.
The 7+7 blade billet 6262 wheel won’t work in a 6262 housing machined for the 6+6 blade wheel because the 7+7 blade wheel is extended on the exducer in which the 6262 6+6 blade compressor housing requires light machining for the 7+7 blade compressor wheel’s exducer to fit in the 6+6 blade compressor housing.
