Hi Folks, I have an interesting problem.
I have a 1984 Chevy Blazer 4x4 with a thm700r4. The original engine
was a 305 and it was replaced, by the original owner, with a Mr.
After the swap, the engine acquired an appetite for starters. Every
three months or so, the starter fails. (Of course, the owner did not
tell me this when he sold the blazer.)
I have been going nuts, trying to solve the problem. I even bought a
GM rebuilt starter and ring gear and made doubly sure that the starter
was shimmed correctly.
Currently, the truck is located in a small texas town on the border
with Mexico and I asked a local mechanic to look at the problem. He
said something that was very interesting. He has seen that problem
four times - that is, GM Goodwrench Crate Engines that eat starters.
The solution is to replace the 9 tooth bendix with a ten tooth bendix.
The ten tooth bendix is not available in the US, you have to go to
mexico to get it.
Has anyone run into this problem and solution?
