Hello again..

As before, operate the starter off the engine using jumper cables.  Watch to see what is happening with the Bendix unit.  The Bendix is the assembly on the motor shaft, the part with the big spring and the gear.  When the motor turns at high speed the gear should move down an internal helix towards the body of the motor.  From your description it sounds like the gear is not moving which would be common for a used starter that has been sitting around for a long time, particularly if it has been allowed to get wet.

 

You may be able to free the Bendix by washing it with mineral spirits (paint thinner).  Get the Bedix wet with the solvent and work the gear on the shaft until it moves freely (push, pull, twist).  Keep this up until the gear moves freely on the helix... very freely.  When the gear moves freely, apply powdered graphite as a lubricant to the surfaces that slide relative to one another.  Do NOT oil the Bendix.  Oil simply picks up dirt and grease which makes the unit stick.

 

If cleaning the Bendix does not allow it to move freely, take both your old starter and the new one to a motor repair shop.  Ask them to remove the Bendix from the old starter motor and put it on the new motor.  The spring that is part of the Bendix assembly is very strong so replacing or moving the Bendix is a job often best handled by professionals.  I suggest marking one of the Bendix units with a dot or two of paint so you can confirm the motor repair shop has moved the correct parts to the correct motor.

Your "new" motor is faster than the old one but still too slow.  When you connected the second battery cable, the motor should have spun so fast that it moved across the table.  You will notice that in the Universtiy Motors video by John Twist that he had the motor clamped in a vise so it did not jump or move when power was connected.

 

Your new motor could be slow because the test battery is too low on charge or it could be that the motor is "gummed up" and needs cleaning.  If you have another car with a known good battery, try the jumper cable test using that battery instead of the one you have on the bench.  If you don't have another car ask a friend to come over for coffee and surprise him with your request to "borrow" his battery.
