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.

Wow, that's crazy. Gotta love when a simple fix, cures more than one issue.

Were any bolts loose or missing? Usually they don’t crack like that.

I believe the passenger battery negative ground cable is attached the the engine by one of the starter mounting bolts. If that is loose or corroded, the starter performance will be degraded.

when i got the truck 4 years ago my mechanic had a look over the truck and did find the starter a little loose, but the chirping didnt start until a little while after that, or it got to the point that i started noticing it. where the gear comes out was ground down from riding on the flexplate and one of the bolt holes had a crack in it too. im thinking it may have started there. its funny, i almost feel like the truck runs better now that im not afraid its something internal like a lifter coming apart. i can say i wouldve about torn that engine down looking for that chirp before i wouldve looked at the stinking starter!

Highboy1975,
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.

https://www.rockauto.com/en/moreinfo...&pt=4152&jsn=9

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.

https://www.rockauto.com/en/moreinfo...pt=4152&jsn=14

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 thought about the 6.7 starter, and probably would have gone that route, but it was my first day off and i really didnt want to be stuck waiting on parts or putting much extra time in this. our work parkinglot is a mudhole and i just wanted done asap. the 6.4 starter was a nice upgrade and was super convenient. my biggest reason for posting was curious if anyone else had ever had a starter break like mine did. it was a big "wtf" moment when i pulled that old starter off. that was probably the last thing i expected to find going on. i appreciate all the advice, but by my own admission, i just took the easiest way i could out due to time limitations. i usually try to do oem parts, but the napas come with a lifetime warranty and ive got one on my way to work from the house.

Highboy,
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.

The housing was probably already cracking when it was loose, it went farther after tightening. It would have been hard to see unless the starter was fully removed.

There's another point to consider about the NAPA "Warranty"
Part #: RAY 2449309
Line: NAPA Power Premium Plus
$258.99/ Each
+ $44.00 Core



This warranty applies to American and Import cars, vans and light trucks under 8,000 lbs.
G.V.W. For vehicles used for towing, racing, public service, security or government use,
off-highway recreational use, four-wheel drive off-highway competition, fleet or commercial use,
see below.
 Warranty is one (1) year from date of purchase for commercial, fleet, government/
security under 8,000 lbs. G.V.W.
 Warranty is two (2) years from date of purchase for light trucks and vans
equipped with diesel engines under 8,000 lbs. G.V.W.
 Warranty is for ninety (90) days from date of purchase for off-highway/
competition under 8,000 lbs. G.V.W.
This warranty is null and void if the installed Power Premium Plus Alternator or Starter has been
misused, misapplied, contaminated or is not a correct application in accordance with the NAPA
Power Premium Plus Catalog.
With either the 6.4L or 6.7L starter, If you are asked to prove that you actually installed it on a 6.4L or 6.7L truck and you cannot, they might deny the warranty altogether.

NAPA Warranty

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,

Rick

That all applies to under 8,000 lbs. G.V.W. all these trucks are 10k+ so do we not even get a warranty?

I would wonder the same thing. And quite frankly, the parts manufacturer's "should" know this since they are making the parts for the vehicles. Not that hard to get this info.

That would be something to ask NAPA. They certainly do have a warranty for these truck starters. The Bosch for example was 24 months.

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