SERVICE INFORMATION:
Beginning at start of production for 1992 models, all AXODE transaxles were built with a revised
low sprag outer race that required revisions on the forward clutches, both lined and steel plates, a
new pressure plate and "Wave" plate.
Improved durability and reliability of the low sprag outer race.

LOW SPRAG OUTER RACE - The outer diameter of the race was increased from 4.575" to
4.825", and the width of the race was increased from .600" to .725", as shown in Figure 57.
The
Inside Diameter of the sprag race Did Not Change.
FORWARD CLUTCH FRICTION PLATES - Have an increased amount of teeth to 57 Teeth from
the previous 52 Teeth, to accommodate the increased diameter of the sprag outer race, as shown in
Figure 58.
FORWARD CLUTCH STEEL PLATES - Have an increased inside diameter to 4.920" from the
previous 4.720", to accommodate the increased diameter of the sprag outer race, as shown in
Figure 59.
FORWARD CLUTCH PRESSURE PLATE - Has an increased inside diameter to 4.930" from the
previous 4.730", to accommodate the increased diameter of the sprag outer race, as shown in
Figure 60.
FORWARD CLUTCH "WAVE" PLATE - Has an increased inside diameter to 4.930" from the
previous 4.730", to accommodate the increased diameter of sprag outer race (See Figure 61).
None of the parts listed above are interchangeable with previous design parts. If the sprag outer
race is upgraded to the latest design, the forward clutch components
must
also be upgraded to the
latest design level.
When
all of the above parts are changed as a service package, they will retro-fit back to all previous
model AXOD/AXODE transaxles.
