19. Re-install the coast clutch plates, as shown in
Figure 157.
20. Install the coast clutch remover/installer, as
shown in Figure 158.
Special Note: This tool is almost mandatory
for the "PTO" version. The overdrive
clutches must be installed "before" the coast
clutch housing is installed, as they will not
pass by the PTO gear.
21. If you are rebuilding the "Non-PTO" version,
the input shaft can be used, with transmission
centerline horizontal, to install this assembly
and then install the overdrive clutches. We do
not have that luxury with the "PTO" version,
please use the installation tool.
Caution: The overdrive one-way clutch may
be damaged if the tool is not used or installed
correctly. The tool must tightly hold entire
assembly.
22. Set the completed assembly aside for the final
assembly process (See Figure 158).
