were three (3) known types of A-4513, Universal joint housing caps—inner;
four (4) known types of A-4520, Universal joint housing caps—outer
assemblies (not to mention all the variations within); and five
(5) known types of Transmission main shaft bearing retainers.
purpose of the Universal joint housing cap assemblies were two-fold.
First it was to guard and shield the Universal joint from becoming
damaged. The second item was to help stabilize in place the Brake
Cross Shaft Assemblies, right and left, for the early service brake
system. When the arms were discontinued the assembly was for guarding
the Universal joint.
of the Transmission main shaft bearing retainer was also two-fold.
First it served as a retainer for the small rear bearing in the
transmission. Second, it was also used to attach the Universal
joint housing caps—inner and outer with six bolts, nuts and cotter
keys. The Transmission main shaft bearing retainer was installed
upon the completion of the transmission. The transmission was then
installed onto the completed engine and clutch prior to the shipment
to the various assembly plants to be installed into the chassis
at time of assembly of the car or truck.
Most of the
data is represented by the major and minor changes that occurred
on the part. These changes are described and will make it easier
for the restorer to put the right combination onto whatever vehicle
it is they are restoring at a certain point in time.
this study, please remember that the data is represented by original
Ford data. All dates represented in this study are those dates
represented by the part release dates from the individual
part data sheets, not production dates. This study should not reflect
on the information and data in the MARC/MAFCA Judging Standards
and Restoration Guidelines.
restoring a car or truck for judging purposes in a MARC or MAFCA
sanctioned meet, always follow the MARC/MAFCA Judging Standards.
