Dead spot in starter?

Good afternoon folks..

Just wondering.. I think I have a dead spot in my starter. Is there a way to fix that short of replacing the entire starter? Thanks in advance.

The brushes may be bad, if so, they can be replaced. However the commutator (part the brushes run on ) may be burnt. It can sometimes be cleaned up with some fine sand paper and the little spaces between the copper strips cleaned out if not burnt bad.
You need to pull the starter apart for a visual inspection.

Well I guess that answers my question, because the starter is a sealed unit. I guess I'll deal with it having a dead spot until it dies altogether, or replace it when I have a few extra dollars floating around. Thanks for the info.

How do you know that the dead spot is on the starter and not teeth missing on the flywheel?

If it won't turn over at all then it could be a bad spot on the armature. If it engages but then instantly kicks out then it is a Bendix, if it spins but doesn't catch then if could be a bad flywheel.
What do you have to do to get it to start. if you are turning the motor by hand then yes it is probably a bad flywheel if you just keep hitting the key then it is probably the starter or solenoid. These are not sealed units they can be taken apart and repaired if you can get parts. I do it all then time. But realistically most folks buy a replacement starter.

The starter doesn't want to turn at all. When it gets really stuck I take out my rubber mallet and give it a helluva whack. The starter pretty much has a mind of it's own. Most times it works fine, but occasionally it doesn't wanna pay attention, or I have to hold the key a long time (10 to 20 seconds) before the starter suddenly wakes up out of a slumber. At first I thought it was the cables, I checked those and they all look good. I really doubt the flywheel is bad, If it was missing a couple of teeth it seems like the starter would just freewheel in the bad spot of the flywheel, rather than just get stuck.

i had a vw beetle that did that. repeated turning on/off the ignition usually got it to fire.
if that didn't work, push start.. easy on a vw.

best story .. same thing happened to an airplane i was a passenger in. just told the pilot don't worry just turn it on/off a bunch of times.. and she fired! lol it's hard to push start an airplane..

That is either solenoid or the brushs are short usually a pretty easy fix. Brush sets are avaliable at some parts stores. You can also get solenoids but they are sometimes as expensive as a rebuilt starter.

The more I reread your description, I wonder if the problem is the solenoid mounted on the fender well. If is is "sticky," it may take many tries before is come loose and closes the contacts that energize the started. Have some one turn the key to the "Start" position while you listen to or feel the solenoid. You should hear or feel a click. Or, run a test light's terminals over the heavy posts of the solenoid to see if the light comes on when the key is turned to start. No click or light means the solenoid needs to be replaced.
