Purolator oil filter N-51

[motto (RIP)]

The filter element you have is quite close to the Military Junior as used on WW2 Jeep and Dodge. The only difference appears to be the length or height of the Junior element which is 4-1/2 inches as against 5 inches for the N-15. Bore/stem diameter and outside diameter are the same.
I believe that the Military Junior element would be perfectly ok to use with a half inch spacer below and they are readily available. They were quite adequate for the 230 Cu In Dodge which is also a bypass setup.
I am using Fleetguard LF 510 on my Dodge 6x6.

Rick,
Here is what you are after. Check the number again on your filter

Hi All

Rick in your original request yous said "It has a PUROLATOR N-15 cartridge" but the last two post are showing photos of N-51. So would you confirm the number?

Going back to my 1990 Catalog I don't find a N-51 listed but do find a P-51 listed which has a NAPA number of FIL 1100 which should be WIX 51100 here is the link to the NAPA site to the FIL 1100 see if these are closer to what you need. http://www.napaonline.com/Catalog/Ca...100_0297032254 these numbers look closer to your measurements.

Cheers Phil

That links results in a message "Access To Website Blocked" for some reason (non-US residents?).

I read the Junior Military Filter cross-references to AC P-115 and Fram C-21. I'll check what the local car parts store can come up with, at least I have the NOS one to compare.

Hi Rick,

Just looking at the dimensions of the elements you were seeking and I found these two filter elements when I was chasing them up for my F-15A:

Fleetguard LF510 Length 4.87" Dia 3.97" Hole Dia 0.54"
NAPA1006 Length 5.00" Dia 4.094 " Hole Dia 0.553"
(WIX 51006) Length 5.007" Dia 4.094 " Hole Dia 0.553"

Fleetguard LF 510 are available in Dandenong at Whitehorse Truck Parts and the WIX 41006 are available from Brisbane at Australian Engines.

I bought a WiX 51001 from Australian Engines which has a 5.50" length which matched the original element from my F-15A

I recall a local company in Melbourne that had WIX 51006 elements but I had to get the 51001 from Brisbane. A google search should find the local Melbourne agent for WIX filters.

May have posted this photo before but if not here it is for comparison.
Original F15A- Left, WIX51001- middle and Fleetguard LF 510- right

Hope this is of some help and interest.

Still have the Fleetguard LF510 if anyone wants it.

Cheers,

Thanks Jacques and Hanno for the updating of this 2014 thread. I was successful and the Lynx has a new filter installed.

regards Rick.

Thanks for all the input, Jacques and Phil.

But none of the filters you listed are available in Europe. The guy at the local car parts store was very friendly and helpful (he even looked up my truck on the internet), but he could only find cross-references to cross-references leading to one and the same filter - which is too wide.

I contacted Micha Korst of Jeep Dodge parts (http://jeep-dodge-parts.nl/) and he was very helpful and provided both the info and the filter in question: a Bosch P 9170 (order number 1 457 429 170, plus see the picture of the packaging for cross references to other brands).

Attached are some pictures and the product data sheet: Bosch P 9170 ProductDetail.pdf. While it stands 23 mm smaller at 110 mm, the diameter of 98 mm is a good match (2 mm larger). The center tube is 1.5 mm too large at 14 mm (although they all seem to be around the 0.55" mark), but I minimized seepage with a couple of rings.

I am happy to have fitted a new quality product. Will report back after the next oil change.

If anyone finds another (European) match, please report about it here.

HTH,
Hanno

Hanno,
A lot of application info here, it is a UK supplier and good price too.

Hi Hanno

Just to close the loop on the NAPA Filter as the information might be of use see the 3 screen shots of the filter information.

Rick just out of curiosity what filter Make and Number did you end up with?

Cheers Phil

[motto (RIP)]

Looks like the problem is solved Richard.
The number on Rick's old element appears to be N-51.
Bingo!

Dave

[lynx42]

Looks like I need new glasses. I will say that I originally transposed the number in the workshop when it was covered in Black, Black oil. It is N-51 as you can see in the cleaned up photo., Thanks Richard for pointing that out. Seems that we might be able to source one a bit more easily using the correct number.

Regards Rick..

[Lynn Eades]

Excellent team work!

[Hanno Spoelstra]

I am trying to find a (near) local source for these filters. I have a NOS one but I want a modern newly made one.

This is what was listed on the label:
