6.4 starter upgrade.
wellbi was forced into replacing my factory starter today so i did the 6.4 upgrade. im assuming the original was tired, i was getting the occasional long crank start, assuming now that this was due to the tired factory starter. i also inadvertantly fixed a chirp on startup that had me about to pull the valve cover off and the turbo by replacing the original starter. the flywheel had been doing some grinding on the housing of the factory starter. i cant say i expected to remove the factory one in 2 pieces. with the 6.4 starter the truck fired right up after a 2 week sit, and every hit start today was fast enough i couldnt have timed it on a stopwatch accurately, like half second cranks. the truck starts very enthusiastically now and no odd chirping noises. i definately didnt expect to find the source of the noise in the starter.

I know it's too late now UNLESS you can convince the place you purchased your new starter from to accept a return or exchange but I would recommend to go with the even better upgrade and use a 6.7 starter. The only difference is you "should" use some sort of bushing in the bottom hole of the bellhousing to match the smaller bolt that goes into the bottom starter hole. The 6.7 starter spins just a little bit faster even yet. The way it sounds like your truck is firing, you might be able to spin it fast enough to go back in time. Anyway, if it's not too late, I would return it or exchange it. I know "most" places won't accept returns once they are installed or used and it's probably going to be virtually impossible to hide any signs of installation at this point.
This is copied from another post I replied to in another thread:
So, I don't know what people's thoughts are on Napa's starters for the 6.0 but I recently had to get one and opted for the 6.7starter and it was about $175 with giving them my old starter for core.
It comes with a 2-year warranty and I figured that if it goes out, I can take it directly back to them which is 1 block away from my shop.
I'll be honest, I don't typically buy parts from Napa and actually go 3 miles up the road to O'Reilly's if I need something that day because they are typically cheaper than Napa, Advance Auto Parts, and another local parts place in our city. Plus, as most probably know, they match pricing anyway.
I don't really have anything against Napa and actually would rather do more business with them since they are literally right down the street. However, they are almost never cheaper for prices.
I buy stuff from Rock Auto all the time so I'm not opposed to getting a starter online. However, my thought is, if you have to spend the money on shipping your starter to them for a core charge, you're not going to end up saving a lot but I guess that depends on how desperately you need it. If you need it that day or in a day or two, Rock Auto isn't going to be able to do that since it typically takes 3 or 4 days or more to get parts.
I guess you could probably save about $50 to $63 depending on which starter you choose so maybe it's worth it order from Rock Auto.
At the time, I didn't want to wait the week or 5 days to get a starter so I just did the Napa one.
Here are a couple from Rock Auto at I type this:
Here's one from TYC with a "limited lifetime warranty for non-commerical use". - $122.79 WITH NO CORE CHARGE.

Here's one from AC Delco with a 2 year UNLIMITED MILEAGE warranty. - $106.99 INCLUDING CORE CHARGE OF $20. So, if you want to spend the money to send back your old starter, I guess that's that.

As for doing the bushing, I actually didn't even do a brass bushing and actually just went to a local Menards which is as big as Lowes or Home Depot and purchased a hard plastic bushing for the bell housing and a new bolt for the 6.7starter. I think it was about $3 or maybe $4 all together.
I also considered drilling out the bottom hole in the starter so I could use the same bolt but I didn't feel there was enough material that if I wanted to tighten the bottom bolt really well that there was enough aluminum to hold and not fracture.
That's what I would be concerned about. It's probably okay if you're not going to tighten the bottom bolt that tight but for me, I want it tight and didn't want to have to mess around with Loctite.

I understand the situation.
But on the Napa starter, since I just got mine from Napa, I would check again about their warranty. I was told it was 2 years. Unless I got a different "grade" of starter than what you did. That wouldn't surprise me since I was looking for the cheapest starter just to get back on the road at the time as well.
thats what i got. says lifetime of the truck. its odd, the bosch reman is 2 years and is more money. well see if i have to use it i suppose.

Also, I think the F250 and F350 series trucks have a GVW that's higher than 8000lbs so the lifetime warranty might not even apply at all.
Just saying.
Cheers,

Autozone OTOH, appears to offer a "limited lifetime" warranty on a Ford diesel starter that didn't mention GVW
