Do I have a starter problem?

The last couple times I started the CJ left me wondering if the starter is going south.

When I turn the key, the engine will turn over a few times then stop, but the starter will continue to whirl until I release the key. Once in a great while the engine will turn until I release the key, but usually it is "turn-whirl".

I just dropped in a new battery (thanks LumpyGrits ) so I don't think that is a problem.

Do y'all think it is the starter? Drive gear? I've never messed with either. How hard are they to change out?

Thanks everyone..

I will really be glad when I get smart enough to start answering questions instead of asking them all the time!

I would say that you are in the market for a new starter. Sounds like the bendix "drive gear" is spinning on the shaft.

Those starters work on inertia so if you look at the top of your starter theres a cover that you can remove. In it there is a arm that on one side has a magnet and on the other side the finger that pushes the drive gear forward. They are prone to get dirty and then the drive gear does not fully push out.

Take the starter off and clean that mechanism properly and give it some WD40 or other can lube. Youl quickly see that you can fix this yourself once you open up that cover. You do not need to open the whole starter on the long screws.

Let me ask a related question. Over the past three weeks or so one out of every ten cranks will result in a grinding noise. IT doesn't happen every time. Sometimes I alleviate the problem by roll starting it. I have not pulled it off to inspect / clean the bendix gear but the randomness is what concerns me. Knowing that the flywheel typically stops in discrete stops related to compression strokes on the engine I would be a little concerned of a ring gear having a bad spot.

Thoughts?

Thanks guys. I guess I know what I am doing this weekend! Along with finding out why the front hubs won't lock in. And getting the gas gauge to work. And finding out why the heater doesn't work. And putting on steps for the wife to get in and out. And.,..........Does this ever end?????

My thoughts concur with your thoughts - i.e. bad ring gear on flywheel.

Make sure it's not just the starter coming loose (VERY common on AMC motors!)

Ring gearmis very unlikely to be the problem but possible. Start with starter drive gear and cleaning it properly.

You either have teeth missing on the ring gear on the f'wheel, or buggered up Bendix spring and gear on the starter.
Get a new starter and see what happens.

Or take out the starter, and spin around the engine with a breaker bar while you look at the ring gear teeth through the starter hole with a flashlight. It's usually pretty easy to see which ones are messed up.

When the starter was working well (in the recent past), were you getting any grinding? That would be the tell tale of a bad ring gear/flywheel.

If the starter wasn't loose and you need a "new" starter, I'd suggest trying to find someone to rebuild the stock unit, (or exchange it). Those were similar to the old Ford set ups & easy (simple & cheap) to rebuild. Hopefully the guy is using genuine bendix etc.

Unless you can find an honest brand name starter somewhere, the Chinese crap is, well, crap & you'll be replacing it again soon.
