All m939a2 filters that you will need

[DIndFab]

Does the spin on filter upgrade you have listed replace the other fuel filter number? Or are both needed. I thought there was 2 fuel filters.

I just returned home from Napa, and you have to ask for the "ATI or AITI sale". I just BS'd my way through it and told him that the friends I had on a forum I belong to told me about this sale. That's when he stated something about the a fore mentioned.You have to state that it's about "big trucks/heavy equipment".
I didn't do nearly as good as the poster of this thread. (sorry, bad memory), but I got the oil filter, seal, and fuel filter for 43 bucks out the door.Of course I have to wait until Monday to pick this stuff up, but looking at their regular prices, the fuel filter alone was $52.25. So I'm happy. I just wish I didn't have to bust my tail to get off work in time to get there...... But if not for this thread then I wouldn't have saved some money. I do thank you for that. Just a heads up before next years sale would be greatly appreciated. After all, Like I said, my memory sucks.

Yes the spin on filter replaces the big canister filter on the frame rail in the drivers front wheel well. It fits in the factory holes that the canister fits in to. Makes the filter change cheaper and easier.

Thank you for this. I printed off a copy for quick referrence later.

Well if you missed it, it was napas farm day sales and I took complete advantage of it and loaded up on filters. I won't post prices until someone says it's ok to have prices posted.

So since there's not a clear post on all the filters with pictures all in one post, I figured I would make one for you guys and hopefully it helps.

ATTENTION ALL NEW M939a2 OWNERS: these are all the filters you SHOULD replace as soon as you get your truck! Especially the air dryer rebuild kit, even if it's functioning it will save you a lot of headaches down the road.

ALL NAPA PART NUMBERS

Canister fuel filter (if applicable): 3401
Block fuel filter : 3472
Engine oil filter : 1649
External transmission filter : 1268
Hydraulic winch filter (if applicable): 1467
Air dryer rebuild kit upper: DQ6026 (not pictured)
Air dryer rebuild kit lower: DQ6020 (not pictured)
Spin on fuel filter head, upgrade for canister fuel filter: 330236700S
Spin on fuel filter: FS1006

5tonman1971: is the air dryer part number the same for the M923 ( not the A1 or A2 )

 

[5tonman1971]

I'm not sure if the a0's have the air dryer but if it does then yes they are the same unit.

The only filter I see missing from this post is the internal transmission filter.


It's part # is 51892 (Wix) or 1892 (Napa). They run about $35.

Just punched the Napa part number into their site... $62.49.

Another filter number is the inline fuel filter that some A2's have(mine). Napa 3248.

The pricing varies depending on you location the filter is 38$ in my area.

Does Napa have any other truck filter sales during the year, or just that one time per year?

They have it twice a year one in the spring and the other one is in the fall.

Man, you're right. I just looked up the Napa store about 15 miles north of my local store, and their price is $104.95 for the trans pan filter! I'm not joking either.

 

[5tonman1971]

That is insane!

 

[RustyM923]

I don't buy from napa...thus $35

 

[M35A2-AZ]

Fleetfilter.com has it for $32 and if you buy $125 it is $29 and if you buy $200 it is $26. It pays to shop around for filters for sure.

If you go to NAPA, be sure to sign up for your AITA membership, since you own a "big truck/heavy equipment piece." It gives you a substantial discount on parts/fluids/supplies and is free. Mine automatically renews every year as long as I've bought parts with it the previous year. Most likely this sale was for AITA members.

So that's why my NAPA wasn't having the sale on the filters. It was only for AITA participating dealers- the closest of which is about 86 miles from here. There aren't any AITA participating NAPA dealers in South Jersey.

any chance you have a picture of the filter adapter and spin on filter installed?

Yes sir, here's the one on my m813a1 but it's the same as a m939 series truck.
