FOR
FINAL
ASSEMBLY
The r e m a i n i n g transmission components
(clutches,
front band, o i l pump/reaction
shaft support), are
much easier t o i n s t a l l i f the transmission case is i n
an u p r i g h t position.
Two methods can be used to hold the transmission
case u p r i g h t . T h e f i r s t method involves u s i n g a C-
clamp style transmission h o l d i n g tool. T h e second
(and simpler) method only requires modifying a shop
workbench.
Workbench modification involves d r i l l i n g or cut-
t i n g a 8.89 c m (3-1/2 inch) diameter m o u n t i n g hole
i n the bench; t h e n c u t t i n g notches at the hole sides
large enough
to clear
t h e output shaft
support
flanges.
