I got a very heavy package delivered to the house yesterday: a shiny remanufactured starter motor from AC Delco. The weekend forecast is for warm weather but showers and thunderstorms, so I probably won’t be able to take advantage of the time to put it in.

Top: original crusty starter motor pulled in 2011. Bottom: sexxxxxy new reman unit. Y’know, I think I’m going to bust out the pressure washer and see if I can clean the old one up.

One of the things I’ve been thinking about are the points of failure and wondering what they might be. It’s been so long since we pulled the last unit, I don’t remember what the issue was—if it was making the same noise, stopping intermittently, or something else.

There’s the possibility that there are missing teeth on the flywheel, based on the sounds the engine is making when I turn the key. It could be that the solenoid isn’t working correctly, and getting stuck could be the reason I get a grinding sound. It could be that the contacts aren’t clean enough, which means there isn’t enough juice getting to the starter (the single biggest current draw on the whole truck). One other thought is that we didn’t get the bolts snugged tight enough in 2011 and they’ve come loose.

Once the contacts are clean on both sides, and the new starter is in place, I should be able to walk through the rest of the symptoms and figure out what’s happening. And hopefully, there will be no more grinding.
