Flexplate starter clearance *picture*

Hi folks

My engine is repaired and ready for assembling in the car. Last time i did sometimes notice a crying noise from the starter. I checked it an made these photos. Can it be, that's the clearance is to much?

Any advices?

kinds regards

Robert

That to much clearence, needs to be tighter. Should be pretty close to the thickness of paper clip wire. You can use different thicknesses of washers on the inside or outside starter bolt to get it closer. Can't remember which one, I've got it written down at home.

It is not uncommon that the starter base mount has to be machined .060" then use shims to get correct clearance. I used to do several every year.

If it has shims on it now, remove them, and recheck. If not, That starter may have the wrong nose piece on it. Or, you can do as mentioned above. By moving the starter up, the clearance will be less, making it closer.
Here's a quick reference picture I grabbed for you to see. You need to check the clearance at different spots. Making sure any run out in the ring will not be to tight. V 8 stops at about the same 4 spots (locations) all the time on the ring gear locations.

ps: If you don't have a starter back brace to block, you should use one.

Thanks for the replies. Starter is assembled without shims because shims will increase the clearance.
In my though the best solution is to mill the starter base 040-060" down.

My engine is a Buick 455 and its hard to find a starter back brace to block. I hope it will work with proper timing (MSD 6530 i can programm very less advanced timing while cranking) it will work without one.

Shimming the outboard bolt will tighten the clearance. Start by cutting a full length shim in thirds and using the two ends under the outboard bolt. Re-measure, and shim accordingly.

The brace really makes a difference. Also check to see knurling on the bolts hasn't worn down. The knurling is there to keep the starter from shifting around.
