Starting Issues
1986 f-150
I have a 351W 5.8L that is have starting problems. The problem is that the starter is not engaging the flywheel. First I got a new starter and it still did not work. I got a shim and it worked great for about a month and the same problem happened again. I then tinkered with the shim and it worked great for another 2 weeks. Now it seems I have to mess with the shim almost everyday just for the truck to start. I need a fix that will fix the problem for good. Hope someone out there can help.

The two most common answers i see to this are:
1) Are you using the correct starter? They're different, depending on auto or manual trans.
2) Faulty or defective starter; shims should not be needed on any Ford engines.
This is assuming a stock truck, all bets are off if the flywheel has been changed.

Thank you for the help,
So I got a new starter, and I got the correct auto transmission starter. I installed it and the same problem occurs. The starter spins but does not engage the flywheel. I put the shim in and then the truck starts fine. From past experiances I know this is not a permanent fix. Any other suggestions for this problem?
2 ideas I thought of:
1.) Grind down the metal around the starter housing on the Tranny
2.) Buy a new Tranny

Have you given the flywheel a good inspection? The ring gear could have slipped out of place.
Only other thing I can think of that would cause the mesh depth to change like that, would be thrust bearing inside the engine allowing the crank to walk to/fro.
Unless the starter drive stop ring is continually popping off, letting the starter drive travel too far, missing the flywheel......
