more starter problems

I was having a lot of starter problems when i bought my 84 CJ7 about a month ago. It sounded like the bendix gear was getting in a bind or something on the way back into the at rest position. I tried a few starter modification techniques but nothing seemed to work. The Ring Gear didnt look insanely bad but I was beginning to think I might need to replace it.

I removed the trans and transfer case. Then i removed the bell housing and found that the holes for the starter were deformed and elongated.

So i replaced the bell housing - replaced the ring gear - along with the clutch and pressure plate just for good measure. I replaced the starter again with a Napa Premium starter.

When everything went back together I started it back up and it was even worse than before. It was grinding from the start. Same sound - but the whole time the bendix gear was activated it made a terrible grinding sound.

Im stuck. Dont know what to do. I have almost completed the mechanical section of my rebuild but this is holding me back.

Please Help.

Since it was you who pulled the bell housing off do you remember if there were dowels sticking out of the block in the lower corners?

If there not their you need to put some in.

Would you have a picture of the block with the dowels in there? Without knowing what to look for I am not sure if they were there.

They are hollow round pins stuck in the engine block at the lower 2 outboard bell housing bolt holes.

If there were not 2 round hollow pins sticking out you need them.

I don't have a parts diagram. But I got mine from the dealer. And saw them on the drawing.

OK my block definitely had both dowel pins to keep it aligned. My dad was helping me put it together and remembers them both being there

There are plenty of previous owner syndromes on this forum and the havoc they caused.....

I don't know if AMC always used the ford starter on the big 6. but if the flywheel is the correct year as well as the bell housing and starter........you get my point. Something is wrong or has been changed.

Also had starter issues when I 1st got my Jeep, a real PITA! High pitch grinding noise and difficult to start. My starters used to break, e.g. nose cone bust off, gear broke. In the end I replaced the ring gear, even though the previous one didn't look to bad. Seems like once it starts grinding the ring gear does not last long.

If you have the alignment dowels and you've already replaced the ring gear, then the only thing that comes to mind is that starter solenoid and/or wiring to starter, maybe there is not enough juice to fully engage the gear. Try painting the starter gear, and then do a start. Pull the starter, and see how much contact you are getting.
