Power Flow (cont'd)

In 1st Gear

  • Hydraulic pressure is applied to the 1st clutch, then the 1st clutch engages the secondary shaft 1st gear with the secondary shaft.
  • The mainshaft idler gear drives the secondary shaft via the idler shaft idler gear and the secondary shaft idler gear.
  • The secondary shaft 1st gear drives the countershaft 1st gear and the countershaft.
  • Power is transmitted to the final drive gear, which in turn drives the final driven gear.

In 2nd Gear

  • Hydraulic pressure is applied to the 2nd clutch, then the 2nd clutch engages the secondary shaft 2nd gear with the secondary shaft.
  • The mainshaft idler gear drives the secondary shaft via the idler shaft idler gear and the secondary shaft idler gear.
  • The secondary shaft 2nd gear drives the countershaft 2nd gear and the countershaft.
  • Power is transmitted to the final drive gear, which in turn drives the final driven gear.
