If you read yesterday's blog, and guessed (like I did) that I would be ordering a new starter drive you would be wrong.
I pulled the starter, got it on the workbench, and took it apart. When it came time to remove the old drive, I found that it was totally frozen to the shaft.
I tried every tool in my shop, and could not break it loose. After several hours I admitted defeat and ordered a complete new starter assembly.
