Power Flow (cont'd)

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.

3rd Gear

  • Hydraulic pressure is applied to the 3rd clutch, then the 3rd clutch engages the secondary shaft 3rd gear with the secondary shaft.
  • The mainshaft idler gear drives the secondary shaft via the idler shaft idler gear and secondary shaft idler gear.
  • The secondary shaft 3rd gear drives the countershaft 3rd gear and the countershaft.
  • Power is transmitted to the final drive gear, which in turn drives the final driven gear.
