Re: The case of the mysterious clutch. (71 C10)
Hi Everyone, I have a problematic update for you.
I replaced the clutch and ran the truck without a problem for about a week. Now, it won't start. There is a very odd noise being produced by the starter. I uploaded a video of it to youtube so you can listen to it first hand and get some more background info. I don't know why the audio got screwy and is off a little bit, but you can still hear everything fine. Here is the link My suspicion is that the flywheel is just too damn close to the starter housing, but if you've followed this thread from the beginning, you'll know that I am a beginner and my suspicions are as helpful as dirt in a dessert. Any help you can give me would be terrific. Thanks |

I couldn't figure out why changing the water pump would have any bearing on this whatsoever, but just for the sake of it, I loosened up the timing belt. As soon as I did this, it started right up. I thought all was well, but from then on is started making the noise intermittently. I don't know if that helps, but I forgot to include it earlier! |

Re: The case of the mysterious clutch. (71 C10)
Got any shims between the starter and the engine block?
Quite the beardsmith, nice work!

Re: The case of the mysterious clutch. (71 C10)
No. Another friend just mentioned that as well. I think it will be might be the next thing to check out. The thing that I'm thinking though is that when I got the flywheel ground down, the machine shop guy told me that they "took a lot off cause it was pretty bad". Being new, it's hard to conceptualize, but I think that I need to get closer to the flywheel teeth, not further away (which is what I would assume shims would do for me.) Thoughts?
Thank you Sir. You are a gentleman and a scholar! |

Re: The case of the mysterious clutch. (71 C10)
Not 100% positive as I've never tried it but I'd think if you shimmed only the outer bolt it should bring the starter gear closer to the flywheel. Have you got under the truck and seen/watched how close the starter gear is to the flywheel?
I put a new starter on and with no shims it has never given me fits.

Re: The case of the mysterious clutch. (71 C10)
You need to pull the inspection plate off and see if there are any teeth left on the starter and or flywheel. Machining the flywheel surface will have no effect on the teeth on the outside of the flywheel. Either the starter is shimmed wrong or there are no teeth left on it. When you had the flywheel off did the teeth look chewed up or did they look to be in good shape?

Re: The case of the mysterious clutch. (71 C10)
Normally the shims will pull the starter farther away from the flywheel because its too tight and making the starter drag

It must have just gotten grabbed at some point and pulled in towards the mainshaft and crumpled up in there. Anyway, long story short, not bent to keep the starter from engaging, rather, it was bent/crumpled like a tight collar around the main shaft and sort of stemmed/wedged between the flywheel and the engine. Lesson = Learned. ![]() |

Re: The case of the mysterious clutch. (71 C10)
I got a napa clutch this summer an replaced my old one. It works awesome! I paid around 140. Make sure to get your flywheel resurfaced before putting it back together.

Re: The case of the mysterious clutch. (71 C10)
Sounds like the starter is either too far or too close to the flex plate, the flex plate is out of round, the flex plate is thrashed, the bendix could be thrashed, the bushing in the starter nose could be worn or the engagement lever is worn.
Does it happen intermittently or every time? How does the flex plate and bendix look? Is there lots of play in the front starter bushing? Does the bendix come all the way out when you hit the key or just part way?
