Reverse Gear
In reverse, input power is through the reverse clutch.
When applied, the reverse clutch drives the front
sun gear through the overdrive hub and shaft. The

Transfer System

The F4ACl transaxle uses a transfer gear system to transfer
power from the output shaft of the rear carrier to the transfer
shaft. The gear that is splined and bolted to the output shaft
of the rear carrier i,s called the output shaft transfer gear. It
supplies power to the transfer shaft transfer gear which is
splined and retained by a large nut to the transfer shaft. The
bolt and nut that retain the transfer gears to each shaft must
be tightened to the proper torque specification. Proper torque
is essential for two reasons; to keep the gears on the shafts
and to maintain the bearing settings that provide for long life
of the system.
Both gears have helical cut teeth designed for quiter operation.
The overall gear ratio of the transaxle is in part determined
by the transfer gear ratio.
Low-reverse clutch applied
(holds rear annulus front carrier)
rotates the front carrier assembly pinions. The front
carrier is being held by the UR clutch so the pinions
are forced to rotate the Jnt annulus/rear carrier
assembly in the reverse direction. Output torque
is provided, in reverse, with a gear ratio of 2.21::1.
