Which components are on the oil pump shaft?

• A. Tach generator; T5 system; Oil pump
• B. Tach generator only
• C. T5 system only
• D. Oil pump only

Answer: (A)

The drive shaft that powers the oil pump is often used as a shared drive for multiple engine accessories. Mounting the tach generator and the T5 system on the same shaft ensures they rotate at the exact engine speed and stay properly timed with the oil pump. The tach generator needs a precise RPM input to drive the gauge accurately, and the T5 system relies on a consistent rotation reference for correct operation. Since the oil pump itself is driven by this shaft, all three components end up on the same shaft. That’s why the components on the oil pump shaft are the tach generator, the T5 system, and the oil pump itself.
