Starter shims.... \'86 Blazer K5 305,AOD
Tried search, tried my manuals, tried my books, but I just can't seem to find much of anything out about starter shims. Changed the starter on my 'new' 1986 Blazer (305, AOD) the other day. There was one shim in there the way I got it, so I cleaned it up and reinstalled it with the next starter. Have a bit of that high pitched whine when it's cranking and some kind of a clunk just before the engine fires up. Anyone have any tips on getting this right? Trial and error or is there a science to this? Guess I just lucked out in the past and never had to worry about this on any of my GM vans or cars.
