My flywheel had to be replaced recently and I was wondering what some possible reasons for damage could be. I couldn't think of any and I wanted y'alls input. The damage was to the teeth of the flywheel. I just want to make sure it doesn't happen again.

Well, he said flywheel so that would indicate a MTX. The starter could be bad or loose causing the teeth not to line up.

ATX also have a flywheel [its what you bolt TC to] did you install or have it done? whoever did work ask if starter was loose when they pulled it and if you can check starter teeth for damage also.

NO THEY DO NOT!!! They have flexplates, totally different than a flywheel. The only thing that they share would be the teeth and the fact they both bolt to the crank. A flexiplate will not perform the same function as a flywheel.

Ricky,
Read ShoRunners sig...you'll see that he has a clutch, so most likly its a MTX.

Sho-runner:
chances are, like stated earlier that its problably your starter not engauging properly. Do the teeth look okay on the far side?

YamahaSHO,
Both are similar, yet completly different at the same time. Only thing they have in common is that each application (both) are used to start the car, other than that they are completly different in function like you said. YOur sig says your now looking for a 3.0L, what happened to the 3.2L swap idea???

I want to bore and rebuild, its like having a new motor. Plus the block will be "seasoned" which is even better than new after I bore.

SHORUNNER,

If you still have the same starter in the car it would be a good idea to pull it and have it inspected.

The gear may not be fully engaging, may not be fully disengaging (bad bendix), it may have a bent shaft (rare), or it may not be mounted correctly (Shimm(s) lost or corroded), or just got loose (sh-t happens).

I would hope that the shop that did your flywheel would have checked the starter as part of the service. Ask them. If they checked it out, relax.
If they did not, then do it yourself, or have it done.

Broken flywheel teeth (ring gear), or flexplate teeth (aka "waffle plate") are almost always starter related. rangerj

yes the starter was messed up(and was replaced)...its teeth had also been ground down to where it couldn't engage...but the mechanic said this was caused by the flywheel, but i guess if it wasn't engaging properly it could screw up the flywheel.

Could a previous owner have had a bad habit of trying to start an engine that was already running? It sounds like the cause may have been an improper or malfunctioning starter bendix.

Here is what my flywheel looked like at 271,000 miles. 265,000 of those miles were covered with the original starter. The teeth have some wear from the many engagements of the starter. I have never tried to start it while running. It's just not hard to know that it is running. It's not like it is quiet.
