Theengine'srotatingforcedeliveredthroughthemainshaft(1)istransferredtotheforwarddrivinggear(3)or
reversedrivinggear(4)byselectionofthemainshaftsleeve(2).Then,thispowerrotatesthemainshiftdive
shaft(7)throughits44Tgear(forwarddriving)(5)or35%gear(reversedriving)(6).
Asthedrivegearsforeachspeedarexedtothemainshiftdriveshaftwithsplines,thisshaft'srotationturns
thedrivegears,deliveringtherotatingpowertothegearsengagedtothemainshiftdrivenshaft(8).
Themainshiftdrivenshaftisconnectedtothehubforthe1st/2ndgear(9)andthehubforthe3rd/4thgear(10)
withsplines.
Therefore, when the sleeve is engaged with the required speed gear, the rotating force delivered to each
speedgearofthemainshiftdriveshaftissuppliedtothemainshiftdrivenshaftthroughitsgears.
