Input Shaft Bearing Assembly
An input shaft bearing assembly is pressed into the front case
of the transaxle. The assembly consists of the bearing housing,
bearing, and seal. The seal prevents transmission fluid leakage
into the clutch disc area. Individual components are not service-
able, if any of the components fail the entire assembly must
be replaced. The clutch release bearing rides on the smooth
round surface of the retainer during clutch operation. Grease
is not required on the retainer where the release bearing rides.

First, second and reverse gears are machined on
shaft gears. The speed gears all have clutch teeth
the shaft. Third, fourth and fifth speed gears ride
and cones, which are used to equalize shaft speeds
on caged needle bearings that rotate on the shaft
during shifts. The clutch teeth engage with the syn-
journals. All of the forward gears are helical-type
chronizer sleeves and the cones engage with the
gears, and are in constant mesh with the output
stop rings during a shift.
