First I would like to say "Hello" to everybody out there. This is my first time on FTE. Well to begin with I have an 1994 F250, 460 engine. I had my starter replaced by a friend because it would not do anything at all. Had it tested and it was bad. Replaced it with a rebuilt. Compared the old starter with the rebuilt and they were the same. When we started the engine it made grinding noises while cranking. But it would start. Was camping so we thought I would drive it home the way it was. After a few starts it would catch some and then spin. Tried turning the engine by hand so to get different postions on the flywheel. Without very much success. Not sure if the flywheel had been damaged or bendix. Was wondering if it may need shims or something? Plus was wondering if there were different noses on the starter that year? Any suggestion would be appreciated. Thank You very much for your time.
Wanted to Thank you for your input alchymist. Guess it would not hurt to take new starter and get it tested. Ya, I've shimmed a few chevy's. Can't remember doing any Fords myself.
Welcome , I'm new too and trying to get going here.
I know this may sound silly but have you checked your starter and bat cables?
If they have a high resistance they won't supply sufficiant crancking juice to the starter and it won't want to work the way it should.
Good luck.
Wanted to Thank you for you reply. I'm going to take the new starter and get it tested and will check out all wires and cable connections. My one question for you is "Would high resistance cause it to make a grinding noise?". Thanks again and have a good day.

Well I mostly through that in as a general statement that is sometimes over looked when troubleshooting starters, however, if the new starter already sounds like a broom handle in a garbage disposal then I would say you have a mechanical problem with the starter. If this is your second time replacing the starter in so many days you may want to go to another supplier.
As for gear alignment, it would not be the first thing I think of because you didn't seem to have that problem with the original starter. That is you didn't indicate it as a prior symptom.
Wouldn't hurt to inspect the fly wheel teeth, but I am leaning toward the likelihood that your supplier may have a substandard rebuilder.
One thing I always keep in mind when buying things that have problems early. were they made on Friday when everyone is thinking about Miller time, or Monday when they are hung over from too much adult indulging from the weekend?
Let us know the outcome.
Will be taking the starter out and get it checked. Here is something I did not mention. I forgot that the top mounting bolt hole in the bellhousing had been stripped at sometime. Someone drilled it out and replaced it with a nut & bolt. Maybe the bolt dia. is too small and there is movement in the hole. When I take the starter off that will be something worth checking. At first you don't succeed, cry and try again. Have a good day .
I relate to Cry, Cry Again, what I'm doing now too.(I tend to cuss more than cry, don't know if either helps)
I would think that if the nut-bolt set up is tight the starter should be fine for a while but I would fill the new hole with a bigger bolt when you replace the starter.
Misalignment may well be the problem. Those starters put out alot of tork so they need to be bolted up right. Keep at it.
Umm correct me if I am wrong but the top mounting bolt on a 460 bellhousing is not threaded the starter is supposed to be threaded, and the bolt comes in from the back side of the bellhousing into the starter. So if your running a bolt through it then it's without a doubt to small, and you need to look at the starter to make sure it's threaded, and get the right size bolt to put into those threads, and bolt it up correctly, and to answer the question in advance yes this will cause a grinding noise.
I have had the same problem on my 460. I found out that there are 2 different starter drives, one is slightly larger than the other. Napa is where I got mine, went with the larger one and now no more starter noise. If you need the part # let me know.
Yes please do send me the part # of your NAPA starter. The replacement starter I have is also a NAPA purchase. Sure would be nice if it is the solution to my problem. Got my fingers crossed. Thanks again for your reply.
bgreggy sorry for the delay . Here s the part numbers of two different starter drives. Part # 6561106 has 9 teeth and is .990 in diameter. Part #6561137 has 10
teeth and is 1.09 in diameter. My starter came with the 9 tooth drive , @ its replacement did also , they sounded terrible. Got to looking in the parts book @ found the 10 tooth drive was used on some applications . So I tried it @ the problem was solved Starter works perfectly.
Good Luck HOTWRENCH

Good information. I have it printed, and will look at mine.
