Starter Motor

I have a rebuilt 1951 Merc starter motor. Does anyone know if this will fit a 1950 Ford 239? Thanks.

Yep.....perfect interchange.

Thanks. That is what I was hoping to hear!

As long as it is not an automatic transmission starter used with a stick shift, or a stick shift starter used with an automatic transmission or the first time you hit the starter button it could be:

&quot;OH NOOOOO!&quot;

I beleive the Merc starter is from an automatic. Mine is a stick. Is the difference in the starter drive? Thanks.

Yes, and the shaft too.

OK....let me back track a bit. I pulled up my parts books and here's what I found:



1) The '38-46 parts book refers to the starter assy (less bendix) as #18-11102. This number is good from 1932 up to 1946 (includes for V8's and Sixes. The armature/shaft assy is #18-11005. The end cover (part closest to the flywheel) is #18-11130A (for 1938-46 all V8 and Six motors).



2) The 1948-51 truck parts book refers to the starter assy (less bendix) as #7RA-11002. Based on the prefix, this number was introduced in 1947 and the book says it is the correct number for the 1948-50 V8's (100hp). The '48-50 Sixes (90hp) called for a #7HA-11002 starter. The armature for the 7RA-11001 was a #18-11005 (for 1948-51 V8 or Six motor). By this time, the end cover was a #7RA-11130 (for 1948-51 V8 or Six).



3)The 1949-52 Mercury parts book starts to deviate from the above info. They list five versions: the #7RA-11001 as described above, for the 1949-40 Merc (std trans). Then it lists the #1A-11002A starter assy for the 1951 Merc (std trans). The 3rd version is the #1CM-11002A starter assy for the 1951 Merc (mercomatic trans). The 4th one listed is the #FAD-11002A for the 1952 Merc (std trans). The last one is the #FAE-11002 for the '52 Merc (with auto. trans).



Some of the differences in these starters are in the armatures (18-11005 for the 7RA &amp; FAD starters; the 1CM-11005 for the 1CM &amp; FAE starters). The other key difference is the end plates (7RA-11130 for the 7RA, 1A, and FAD starters; #1CM-11130A for the 1CM &amp; FAE starters). It is also noted that the 1CM and the FAE starters included a separate &quot;band, starter cover&quot; which carried a p/n 1CM-11125A. I see that Starter Drives (the bendix assy) are also different. The good old #B-11350 used from the 1930's was carried on for all the 1949-52 merc starters with STD TRANS. When it comes to the Mercs with the Merc-O-Matic transmission, the bendix assy was either a #1CM-11350B (for the 1950-51 auto trans cars) or a #1CM-11350C assy (for the 1950-52 auto trans cars). This is not a mis-print...the 11350C assy apparently fit the older 1950-51 cars too). Many parts are different from the old B-11350 bendix starter assy.



Finally, there are several different versions of the &quot;Cover Assy,Flywheel Housing&quot; which we all know as the starter plate. This is the stamped sheet metal part that fits between the motor block and the flywheel housing/bell housing. Since it includes the threaded mounting holes for the starter bolts, it is key to getting the starter mounted correctly.



The 1948-51 Ford Truck parts book lists this as #8RT-6366 for 1948-51 V8's. Consulting my 1948-55 truck book, I see that they list a #8RT-6366A for 1948-52 (has a 3.26&quot; radius opening) and a #8RT-6366C for the 1953 V8 (has a 2.12&quot; radius opening).



The 1949-52 Merc parts book lists four versions of the starter plate:

#8CM-6366B for 1949 only

#8CM-6366C for 1949-51 (std trans only)

#1CM-6366 for 1951 (std trans only)

#EAB-6366A for 1952 (not defined whether auto or std trans. Maybe no difference).



I dont have the corresponding 1949 to 53 Ford passenger car parts books to check the numbers in there, but it's apparent that there were some differences in the starters as Ford moved into the 1950's. There may be an easy way to tell, such as overall length, but I don't have any dimensions to provide here. If anyone else can update the missing info to add to this thread, please chime in.

I have a 49-54 Ford Canada parts manual &amp; the starters seem to match the US ones...

...allowing for the 54 Canada car body sitting on a 53 Flathead chassis.



In NZ we didnt get any auto's from 49-54 so all the starters interchanged -34-54 no problems.



Only the English Ford Pilot starter was different, for some reason they gave the sump/pan locating instep an oval shape instead of round [which matched their pan opening].
