I recently bought a new starter it was the same as the old one and installed but the old starter was quite loud so I decided to shim the new one and I went to go crank it over and its even worse then the old one, any answers, I guess I will just pull it out and put it back in with no shims. It is a 1968 camaro any info would be great thanks!!also it is just a stock ac delco starter.

From autorepair.about.com..

"Install the new starter in the reverse order of removal. If you took out any shim(s) on the General Motors type starter be sure you install them with the new starter. This will usually be correct, but if there is a abnormal noise when the engine is cranking or a whine after it starts, you may need to adjust the shims as follows:


If there is a starter noise when you crank the engine, remove one shim.


If there is a high-pitched whine after the engine starts, add a shim one at a time until the noise disappears. DO NOT use more than four shims. To add a shim, loosen the inside bolt, remove the outside bolt, add the shim and then retighten both bolts."

Hope this helps!

When you put a shim in it moves the starter away from the flywheel . Maybe it needs to be closer instead. Easy way to do that is cut a shim in half and put it on the outer bolt. That will rotate the starter closer to the flywheel. If it works, you can buy me a Pepsi. :cool:

You can also buy the individual starter noses from GM, for both flywheels and they require no shims.

Starter make be hanging crooked too. Did you install the brace at the end of the case to the block?

Also, the starter bolts may be worn or incorrect. These are special bolts, with a knurled area just at the bottom of the threads. The knurled area is an interference fit in both the starter and the block and it helps lock them together. try new correct starter bolts. Like Kevin, I'm a big fan of nose braces as well, get one if you don't have one.

make sure the bolts aren't bent. if you let the weight of the starter hang on one of the bolts after they are loose, you have a pretty good shot at bending one.
to check, loosen both bolts, and watch the starter for wobble as you turn either of the bolts. if it wobbles at all, get new bolts, and make sure not to let the weight of the starter hang on the bolts before they are tight.

To check for proper fit install the starter and check for clearence. One way is to inserting a paperclip between the tip of the one gear and the gullet of the other gear. You should be able to move the clip with little or no effort. After breaking several noises, (because it was way too lose) I wound up having to machine the mounting surface of the starter to get it to fit. good luck Kevin

It might not be the starter at all. If it still makes noise after following the suggestions made by the other members, pull the starter back out and check the flywheel ring gear. A worn or damaged ring gear could cause all kinds of ugly noise.....Jb
