Starting Problems

Hello,

I have a 94 S-10 that had blew a headgasket and locked the engine up. I bought a used engine that was in good working condition, and was even able to turn the flywheel by hand when I got it, so I know it is not locked up.

I have pulled the old engine, and installed the new one, and used the starter off of the old engine, since it is not that old (> a year I would say). I put everything back together, and whent to turn it over, and all it made was a lound knock sound. It sounded a lot like the seloniod, but louder and with more force. I pulled the starter away from the flywheel, and tried turning it over, and the start seemed to spin fine.

What could this problem be? I thought the battery could be almost dead, so I tried jumping it off, and it did the same thing. Any suggestions?

Thanks!

I would have to say make sure yuo put all the wires back on the engine that you took off and making sure that they are tight. The wires I am thinking of are the ones that come from the body and attach on the engine.

Try turning the engine clockwise by putting a socket to the crank bolt. If it turns around a full turn then make sure the engine ground is good and tight. Otherwise your starter will have to be shimmed. I hope the flywheel that came off the old engine was the same as the one that went in the new engine and the torque convertor bolts are on tight.

Cool, I will check the ground on it tomorrow, as well as try to turn it with a socket. I know that when I got it I tried turning it by hand, and it did fine. I did use the same flywheel, but the engine was from the same year truck, with the same transmission, and I checked and the starters are the same for both vehicles. The torque converter was on good when I put it back together.


I guess if all else fails, the mechanic down the road said they would look at it for $25.00, and I would have to get it towed, so hopefully it will be something simple like the ground.

Thanks!

Well, I had the truck towed to the mechanic down the street, and they said the flywheel is a little bit to big. Seems there is three size flywheels for that engine.

I called the place where I bought the engine, and had them verify that it was the same transmission as mine that the engine came from, and indeed it was.


The mechanic wants $200.00 to replace the flywheel, but I have been told that the starter can be shimmed from everyone else. I asked the recipionist if they could just shim it for me, and she came back quickly after talking to the shop owner, and said no, they could not do that. I'm a bit concerned now that I will be throwing away $200.00 for them to change the flywheel.... What do you think?

Also, what all is involved in shimming a starter?

Thanks.

I'm sorry, but in this case you will have to replace the flywheel as it won't match the starter. The number of teeth on the flywheels are different. Shimming the starter will only raise or lower the starter position and helps it from grinding into the flywheel when engaged.

I don't understand why it couldnt, because the starter off the truck it came off of, is exactly the same starter as mine.

Okay, if that starter was of the same engine, then it should work, however, if the flywheel is big, like the mechanic said, it is probably binding along the tranny housing. Did you try turning the crank before towing it down. There might be another problem, like something binding and they need to pull the tranny out to check it.
