Another Starter Problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm restoring a 71K1500. The engine,tranny and transfer case are rebuilt and back in frame. After pre-oiling the engine, I wanted to turn the motor over with the starter. The starter is new and I proceeded with sparkplugs out. When I engaged the remote starter switch, the engine began to turn over but wouldn't stop turning over until I disconnected the neg cable from the battery. The pinion gear was still engaged to the flywheel, I had to loosen the starter bolts to get it to retract. The new starter is fried, just the positive cable and ground made the starter run, solenoid dead. They replaced starter and I used 4 shims on starter 2. The pinion gear is still hanging up. At least the remote start switch is working OK, I haven't fried starter 2. How many shims can you use? Any ideas?

Any chance your flexplate or flywheel is on backwards?

No, flex plate is on correctly. That's partly why I wanted to turn engine with starter. Try to see if there is any issues while everything is still easy to get to.

Could the starter you have be for a different size flywheel? Or is it an aftermarket starter? And there are more than one set of mounting holes.

your problem may go away when you replace your starter. [unless it is a remote wiring issue]. Every time this has happened to me, it is the bushing on the very end of the starting motor has either broken or worn , allowing the bendix to stay engaged after shutting off the key. I have had this happen with a brand new big chain parts store starter too. I would check that first, and if that's it, it's an easy fix.
