NHC250 Spin On Adapter Parts Help

[Speedzilla]

Hey Guys, I have had a spin on filter kit laying around for a while, and want to put it on this next oil change but I am missing some items. Attached are pictures of what I have. I think I am only missing the base gasket and some instructions, would anyone be able to confirm this? Help help as to what brand adapter this is would be great as well! Need to find any missing parts and some instructions. Thanks in advance!

EDIT:

Here is what I found!

This kit is a Cummins 3300923S adapter kit. This is the correct adapter kit for Military vehicle use. Cummins lists this part as obsolete, but I believe this adapter is made by one supplier and sold through Cummins/Wix/Baldwin/Fleetguard etc so hopefully there will be future availability.

The base gasket crosses to a NAPA 5271.

Thank you to member Swamp Donkey for posting my now attached included instructions!

Base gasket would work just like the cartridge filter. The instructions are pretty simple, just swap that in place of the canister/filter with the bolt and torque to 25-35ft-lbs. Then spin on your new filter.

I see there are two thickness gaskets for the folder side, any idea how to choose which one they want you to use? If anyone had a part number for the base gasket that would be great!

That's for the inside to keep the oil flowing through the filter. Goes under the base. Your spin on filter has a ring

Sorry I do not know the right number. But If you go to the Wix site and put in 51954 filter (stock filter for can) it will come up with the list of gaskets used with that filter and maybe you can figure witch one you need.

I will be going to the property Tuesday and I have some kits so I will look at the instructions and let you know about the two different rubbers. Thought it was the thinner one we use but lets wait and see what the instructions say. I have been wrong before.

I used the thick small rubber gasket on mine.

Just found an old thread by JWaller HERE and I can read the same 3300911 on the back of the adapter. (It might have been him I bought the kit from now that I think about it!) His post also shows a box with the Cummins number 3300923S, which is what I found Cummins listed as saying pre-68 engines, but apparently that is the number you MUST use on these Military trucks. The post 1968 adapter is too thin, JWaller shows a picture of it, he bought that first and it didn't fit.

3300923S is listed as Obsolete by Fleetguard/Cummins so I can't seem to find any literature regarding installation.

Just put the gasket between the adapter and the block. Torque to spec. It's that easy.

The baldwin I used referenced 2 different gaskets for horizontal or vertical applications. It was a reboxed fleetguard and I do remember that the older model is the correct ones for our trucks. ( don't go by the year of the truck)

I remember the filter base gasket being much thicker than the original canister gasket.

Sorry to drag things out, but what about the two smaller gaskets? I don't know where or which to use. I also need the larger base gasket.

Again, sorry for being pedantic about it, but of all things to get right I think the oil filter is one of them.

Use the thicker of the two gaskets on the opposite side of the filter (engine side) The filter side does not have a gasket.

I looked this morning and the wix number for the large gasket is #15271 napa should have it.

Here's a picture of the Baldwin filter kit instructions. Not sure if this is yours or not.

The note above the chart tells you which of the small gaskets to use.

Hey, good to know out data matches up! Thank you. After looking at more websites than I care to remember, I finally found the dimensions for the gasket in the original Cummins kit and matched it to a 5271 Napa. Dimensions by the listing are only 2 hundredths off. One will be in for me in the morning. I will report back with my luck!

Thank you VERY much! I think there is only one supplier making the adapter and multiple people selling it, so these instructions should do the trick.

I should be good to go, my M816 thanks everyone!

 

[Speedzilla]

Updated my original post with the found relevant information. Thanks again everyone.

 

[Floridianson]

So what number 3 or 4 for the gasket. We have horizontal head don't we so it would be number 3 the thin one correct.

 

[Speedzilla]

I've heard two people mention using a thicker gasket, and one person using a thinner one. I was going to check for a P/N on the head. I was unable to find anything useful regarding "197093" online, hoping to find a part number when I do my oil change today! I will report back.

I have been selling the kits for a while and utilize the #4 gasket, the #3 gasket is used on the NH (New Holland) horizontal pump configuration.
