Just a forewarning to those with a 6.5 TD. My suggestion is to get underneath and check to make sure you have the bracket that helps hold the starter end housing to the block. Probably applicable to those with a 6.2, as well. It's a REAL pain in the neck to get to, which is why it is usually left off.
Without it, the bolts will loosen and may eventually break. When I had my starter out in March, I was going to check with the dealer to see if there was hardware missing, but I forgot. Last week, I had a bolt break off up inside the block. I was down a few days waiting on parts because I was NOT going to even crank the engine without the right parts attached.
Anyhow, just a heads-up for some preventative maintenance if you have this engine. It may save you some headaches in the future. For less than $2 for the bracket at the dealer, it's a wise investment.
