Is this a genuine original part?

This is a premium quality 4Drive / Aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.

We recommend checking the SKU 400-16158 and the Cross Reference list above. This unit is a standard 160A upgrade for the W900 series. If your current alternator uses a J180 hinge mount, this will fit.

What does "0.5 Clock" mean?

This refers to the positioning of the output terminals and regulator. On this model, they are oriented at approximately the 12:30 (0.5) position when viewed from the rear, which is the standard configuration for Kenworth W900 applications.
