Lost nut in starter

[Kenneth Cole]

Of all things. I was replacing the solenoid in my 1991 Humvee starter when the screw holding the solenoid in dropped down into the starter.
I removed the bolts from the end of the starter but tapping on the cover didn't loosen it. So before I go and wreck something I thought I would ask if there is something else I should do.

Try using some of those expanding pencil stick magnets. Try each opening you find

If it's inside the starter the permanent magnets in the stator will have a hold of it. You're going to need to open it. I don't know your starter specifically but the opposite drive end cover should come off without much fuss as it does on most electric motors. You may want to remove the brushes first so there is no risk of them being damaged.

There are no permanent magnets in a HMMWV starter. and the brushes cannot be removed without removing the end plate first, it is an old school Delco style starter.
I am assuming he is trying to work on the starter while still installed on the engine and has figured out short cuts can lead to problems.

Then you should be able to simply roll the starter over and shake the nut out unless you have put the starter in the vertical in which case the nut could have fallen into the field coils and you may have to completely disassemble the starter to get it out.

Hi
Yes, the nut fell into the starter.
Can I remove the front cover? I removed the bolts from it but wasn't sure if I could just tap it loose.

If it "fell" in, it should "fall" out. BANG IT ON SOMETHING. Sometimes force works.

Hi
First you just don't pick up this starter and shake it. It's very heavy. I have tried. The nut has fallen down into the starter and the slot it fell into is very small. Can I remove the end cover on the starter by tapping it off of the housing? I just don't want to do something to wreck it.

From your description my best guess is that the bolt in question went into the pivot for the Bendix. My first try would be to pick it up at a 45 degree angle with the solenoid on the bottom and "tap" the nose on the ground firmly. I know its heavy. Plan B would be to take the bolts off on the pointy end and remove the housing. At this point you should be able to locate your bolt. If the Bendix is worn also a good time to replace it.
