Shimming a starter
Trying to help a friend get the starter on a blazer he just bought working right. The previous owner had problems with the starter engaging and said he had even spent over 500 dollars at a shop getting a new flexplate and starter put on it. 2 months later it didn't work again.My friend just finished putting a new starter in it and brought it over and it will start but it makes a nasty grinding noise as it does. Thought I'd ask the wealth on knowledge here to help us get the thing shimmed right, or whatever it's gonna take. Thanks in advance.

many "reman" starters have the nose cone machined. I would suggest hitting the dealer for a new nosecone. these shouldnt have any shims at all. I used to have a wire guage for setting the distance between the starter shaft & flywheel. I dont remember the distance so I will have to try to find it.

if it's makin noise the first thing to do is to check the flexplate for rounded off teeth ,it doesn't take long to trash a flexplate
i like the hi=torque ministarters they're easy to install and most have lots of adjustments built in

I had this problem on my 76 Chev years back. What we ended up doing was getting a NEW nose cone....Using a paper clip as the "mesh" gap....milled the nose cone by file until it fit. Haven't had a problem since. That was in '92. Just remind my sons that if starter goes out...KEEP the nose cone. Hope this helps.
Seems as if it was in a "Chilton's Manual" I read that was the difference. I know it's NOT much gap. Billy G

I had a problem a while ago, found out I needed to stop buying starters from autozone. I spent a little extra on a mini stater and haven't had a problem since!

When I replaced the starter and flexplate on my truck, I used no shims at first. With no shims my starter would make a really bad grinding noise. Shim it and start with the thinest.

I had the same problem and shimming it wouldn't fix it. Went to a local auto electric shop and he sold me a nosecone that fixed my problems.

Howdy:
where is a good source for shims? Have a bit of a problem with my 67, but not severe. Most parts counter people here don't know what I'm talking about, and not having any shims to show them (never needed any before), I can't get across to them what they are, or what them look like. |

Usually there is a "HELP!" rack at the bigger autoparts stores........they should have shims there.
I always keep the old housing though. Sure it's more work, swapping ends, but you know it will fit then. |

Howdy;
thanks again, Longhair. Saving a properly fitted nose is the hot tip , but this one was noisey when I bought this truck. Have been taking care of a bunch of other things first so starting on a regular basis hasn't been a huge consideration yet, but will be soon. cowboy33713 |

Better yet take the starter to an Auto Electric sshop and have them rebuild it. There is a very good auto electric shop in Sacramento and I take all of my starters and alternators to them. Three years ago I road my bicycle in the rain to deliever the starter off my S10 4.3L (PIA to remove and install). They were gracious enough to build it in two hours while I went for coffee. Substantial tip offered though not accepted. The rain quit after I got home, go figure Tim

Shims won't fix this one....you are to far away from the flexplate with the conditions you are discribing (go ahead, ask me how I know) you either need to get the nosecone milled or better yet, shop around for a "80 thousands" starter-a Gm starter that is already milled .080 I called the manufacture, Westling starter, westling.com and they hooked me up with the part number and a local distributor and after 2yr of the same crap your friend is going through it was fixed. my part number was 729106s-080 for a 350. good luck

I think it was thirty or forty bucks. I heard someone on here got one a lot cheaper. It uses the two bolts holes straight across instead of the diagonal holes. Gets it a few thousandths closer to the flywheel. I put it on a new starter and kept the new starter's nosecone to put back on when/if I have to replace it under warranty.
