Lengths of the new and old starter armatures?

[John_Mc]

     Hi all, anyone have the lengths of the old shorter (Ford) and the longer 47-48 Lincoln starter armatures?  I believe the old unit is 1/4" shorter than the 47-48 units.

     Thanks in advance.

John Mc,

               I don't have a spare  armature separate from a starter to compare ,but  I have a complete starter from my '46 Ford. By checking the " Lincoln Chassis parts Manual" '36-'48. They show the original  part #   for the starter as 18- 11002-'36-'47.  Big change sometime in'47. The new # was 5EH-11002 '47-'48. The older armature is #  18-11005, the new starter is 5EH-11002. That pre fix  18 is the prefix for 1932 Ford !  .I think the big change was in the starter drives -- Often called "The Bendix".  All of this can be found in the parts book 

pgs.-  178-181.  

               I'am sorry I don't have the parts I can lay out and take photos of.   BUT!  When I was going over my newly purchased (2010)

48 LC w/ HV12  I noticed the end of the "snout" on the pan  where the starter was mounted  , was cut off about 3/8" to allow the 

newer  drive to fit. I also noticed this on my '46 Ford the same thing was done. I repaired both with a section of a standard plain pro-

pane bottle soldered on /finished/ painted. Any more questions "E" me at  larry1938zephyr@gmail.com  or call me 1-410-756-5310

John, I can measure the can on the oil pan for my Mercury engine and measure the overall length of the shorter Ford starter. Will that information help you?

 

Call or text me if it will help and I will send you the info.

John:

I have the 48 model armature that is about 1/2 inch longer, unfortunately, we also needed a new one.  I found a rebuild shop that had an armature on the shelf that worked for a little while.  Must be some other vehicle that used the longer armature, but I couldn't find which.  The flywheels are also different, and supposedly more flexible than the Ford or earlier Lincoln.  I found a Powermaster gear driven replacement at Summit Racing that works if you shim the starter enough, about 3/32 to clear the gear.  Its also shorter overall, and you don't need the flaky bracket to the pan bolt.  However, the starter needs 12 volts.  One idea I didn't investigate was to find a truck 11 inch flywheel and clutch.  Then I think you could use the stock truck starter. Need to check if the crank end holes are the same.
