Clutch, Flywheel, Starter, Grinding

Just replaced my clutch but my starter chewed up from the flywheel and the dust shield also.

Having almost the same issue now and about to give up on the Dyi idea after all this.

Got everything back together and my nice clean flywheel is now chewed up from my starter. Also the flywheel now when running is rubbing the new straight shield. When i turned it back over it scrapped the dust shield and then sounded like it took out the starter.

All the bolts are in the right place, and everything. Starter is trashed. It started chunky then I heard a big chunky noise and cut it off. Teeth are chewed off the starter and flywheel is a bit chewed up.

What am I doing wrong?!?.. I don't have the money to take it to a shop. It's my DD and right now I'm screwed. Any ideas

Re Cap..

1) Had problem with flywheel scrapping my dust shield when pressing the clutch pedal in and grinding into the starter.

2) Replaced clutch, resurfaced flywheel from a 89 yj, new slave, and new dust shield.

3) starter ate it on flywheel. Took teeth off and flywheel is still going into my dust shield and not just when I press the clutch in.

I'd have to say that if your crank moves forward far enough when you depress the clutch pedal for the flywheel to hit the dust cover, your thrust bearings are gone. Do you idle with the tranny in gear and your foot on the clutch for more than a few seconds, such as when stopped at a light? That's the most common cause of thrust bearing wear. Depressing the clutch pedal on cold starts is a cause of wear as well.

You can drop the oil pan, loosen the main bearing caps, and replace the bearings 1 journal at a time. Afterward you'll need to check end play, which is simple and requires a dial indicator and prybar (a lead hammer comes in handy but isn't necessary.)

ETA did you forget to install a spacer between the crank and flywheel when you did the work? I haven't had a Jeep tranny out in forever so I can't remember if there was a spacer.

I think you got it. I do spend to much time on the clutch at lights. I think this might be a bit over my head to change a thrust bearing. Do you have to remove the tranny also when you do this ? Is there a write up on this?

I am going through this right now...
Do you have a starter for an 88?
If you have the starter from the 87 that is the issue...
Because everything listed for the 87's at auto part stores is really 88.
And all the 87 stuff is 86 lol confusing I know...

^^^^^this^^ you said you are using a flywheel from an 89, you need a starter to match. the 87 starter is the older cj type, 88 and up the new style
you will have to redo your wiring as the 87 starter selinoid is mounted on the fire wall, the 88-up is on the starter.
