Can 2008 ford f350 6.4 crank without transmission?

strange question
as to think why the transmission would be missing

motor will crank with the starter motor if transmission has failed

automatic transmission has a neutral safety switch
if that is faulty the starter may not crank

if a stand alone motor
starter motor will need to be bolted on and spaced to match the flywheel teeth

spacing has to be exact replacement for the missing gearbox housing thickness

Car has to be cranked more then once,than a scraping noise and then car starts.i'm scared whats the problem

the gear on the flywheel has worn. the engine stops in one of four spots in the rotation 'cause the cylinder pressure is building. That means the starter has not got the whole flywheel, but only a few teeth in four spots that is starts on every single time. these teeth wear out, then the starter motor cog cant turn the flywheel and you get the screech like you tried to change a stick shift without the clutch!
if you do have a stick shift, then you can park on a slight hill, and roll just a bit with the clutch half out, which will rotate the engine and give the starter motor fresh teeth to work on.
in short, yes, you need a mechanic.....

My Jeep cherokee not starting after removal of flywheel. Is there a specific way to install the flywheel?

The teeth on the flywheel need to be close enough for the starter motor to catch them when it engages. If you removed it and now the starter just free-spins when starting then you may have installed the flywheel backwards and the starter motor cannot reach the teeth on the flywheel. If its making a loud grinding or pinging sound you may need to manually turn the engine a bit to align the flywheel.

My car wont start? i had the starter check and they told me it was good.all it does you just hear the starter spining not the engine.

Sounds like the bendix, the part that pops up and catches the the teeth of the flywheel, isn't catching the flywheel.
Since you've had the starter checked and it was good...I'd say look at the teeth of the flywheel.
I suspect worn or broken teeth on flywheel.

Hope this helps...

My starter is not is not catching a charge from the cilinoid. What do I do?

There are a couple of likely areas: the starter drive, and flywheel teeth. Pull the starter and get it bench tested. Look in the hole where the starter goes in and look for worn or broken teeth.... Hopefully a starter drive as flywheel replacement is a big job.

Starter will not engage with fly weel all the time grinds sometimes starter is new clutch swich is working

when replacing a starter motor, some have shims or spacers to make correct distance when installed. if these wre left out on instalation this will cause the problem. another problem can be incorrect number of teeth on starter motor which will cause grinding sound and prevent correct meshing of teeth on flywheel
it is also common to get a bad new starter
check solenoid

My 1990 Camaro RS starter prblem. I saw the starter drive gear is using less or half of the gear on the fly weel like the starter needs a longer noise and the flyweel has marks from were the starter is...

So the engine is not original to the vehicle?

When replacing the motor, did you replace the flywheel with the one from your original motor or did you use the one it came with?

The cure would be to use the one from the original motor and then use your old camaro starter. It is very important to use a flywheel with the same amount of teeth, if it has a different amount YOU WILL have gear meshing issues not catching, grinding, sometimes starting perfectly while other times sounding like its missing. This is due to to incorrect # of teeth to match the flywheel to the starter.

The first step is to find out how many teeth the original part flywheel had if that's not the one mounted now count the teeth on the current flywheel, it should be either 168 tooth flywheel or 153 tooth flywheel.

The engine block doesn't matter if its from a camaro, blazer or chevy dump truck as long as the flywheel and starter have the proper amount of teeth to mesh. If that doesn't seem to be as much of an issue then you just need to add or remove starter shims until the starter teeth mesh with the flywheel teeth, NOT deeply but at about half way up the lead tooth. See proper gear meshing

Also make sure you did not put the flywheel on backward!!!
Also it may be a good turn flywheel and examine teeth for chipped or damaged teeth.
SAFETY TIP: Always remember to disconnect the battery when working with the starter.

Get a quality starter, not a part from the dirt cheap discount part store. Places like carry cheap **** that can cost you time and nerves. I once had a problem where I tried to by re-manufactured starter, exchanged it 3 times, then went for new, exchanged it twice and then returned it and went to a more expensive quality supplier and got a far superior product that actually worked perfectly. Because the part is new or freshly re-manufactured does not mean that it is a good part. The same goes for batteries, because you buy them new, sometimes they come DOA dead on arrival.

This is what a starter shim looks like

Here is another article on the topic that explains the issue pretty well.

Good luck!

try turning the engine by hand and giving it another try...if able as the starter is out of the way look at the teeth on the flywheel make sure they are not chewed up. if so there is your problem and a big job to replace that...if not just buy another starter and give it a try...your old starter my be having problems engaging the teeth...
