Why my engine wouldn't start...
 
https://i.imgur.com/Cc5DQIN.jpg

I've never seen a flywheel lose so many teeth before!

The engine is from a very tired car which I'm breaking for spares - 186,000 miles on the clock.

Has anyone seen this, or have any understanding of the root cause? I'm hoping that with a new flywheel the engine could live again - and am I safe to use the starter motor that came with this engine? :)

Cheers,
Jim.

Root causes?

Mostly concentrating on the starter.

Improperly installed starter-- incorrect bolts, insufficiently tightened, misaligned
Incorrect starter
Defective/Damaged Starter Gear
Defective/Damaged Starter Bendix
Foreign Material in the bellhousing
Loose Flywheel Bolts
Trying to start the engine when it is already running
Starter not disengaging or kicking in while the engine is running
Letting the starter kick out and back in in one start sequence without letting the engine stop rotating

NOTE: The damage may have been started with a previous starter.

Exactly!

And those happen even more often when a motor on engine stand gets started by DIY (often fishy) wires, screwdrivers etc.
Simply bad timing (or sequence) of when to touch which wire to where...

Starting one of my d24s improperly (it was on engine stand, the very first start after assembled) I timed the starter badly (engine was running at the moment) it cost me 1tooth...:mad:

Starting my other motor on engine stand,
when carelessly sloppy main starting wires tangled for a split moment, my 2nd d24 lost 2 teeth and made me really mad about it.

Idk of it is possible to hear. Lol.... I think i know when it was...:mad:
