They're all Aeroquip numbers, I believe. Not my lingo, but probably Orme Brother's accounting and invoicing system's. I haven't a clue what the "FL" means. Fluid?

Edit: I just called Orme Brothers. It means "flare", "straight" to them.

I've changed that on the site, too.

Thanks, Brendan, for bringing up the question. It gives me a clarification.

OK, I've finally gotten all my parts to install this setup, I just need to drill the holes in the 2" x 4" square-tube piece of steel. Last question:

On the block & stock filter housing, what type of plugs are in there? The square-head ones that I've run in to when doing my CCK & HPX lines?

 

Wow.... THAT I don't remember. One may be.

Sorry.

Pop

 

WOW!!! I stumped Marv!! That deserves a margarita!!!

Maybe someone has a pic showing the port locations before the plugs get removed? Or maybe a picture of the oil filter/block heater cord location that will just happen to show them? Anyone?

 

Instead of a margarita, I sent ya' some reps!

Well, though I can't seem to locate the plugs I removed right now, I know I made this up for SOME reason:



That started life as a 1/2 inch bolt. The head on that bolt takes a 3/4 inch wrench to turn it.

The other one is not a recessed square.

Edit:

OK, I found them. Take an 11mm box wrench and a tool like the above with you under the truck. The square drive will be able to fit into a recess that is .325" square.

somebody posted the pic with both plugs still in place,on was square,the other may be hex

 

An 11mm wrench and that square thing.... man, nothing like common hardware!!

 

This is getting good!

 

One is a square drive which you can remove with an adjustable wrench. The other is a square "socket" drive, and if I remember correctly, I used my socket extension (I think it was the 3/8 drive) to remove that particular plug... or something like what Marv showed can also be made from a bolt for a custom fit.

 

I am wanting to install a by pass filter on my 7.3 and also my 5.9 Cummins. I have went to Pops install site and find this very informative. I have researched the part numbers provided and this has brought me to some questions. I understand a bypass filter takes a small amount of pressurized oil out of the oil flow and filters this oil down to much finer microns over the stock filter.. I understand this bypass filter is capable of filtering smaller particals because there is no reduction in oil to the engine if these smaller particals should clog this filter. Therefore you have much better filtration over the stock installed filter because the stock filter would clog too soon if it filtered all of these smaller particals. Where I not fully understanding this is in the specs of these filters Pop has provided on his site. I went to the Baldwin site and looked up the stock filter number{B7039} and also the bypass filter Pop provided{B164}, but there was no specs on either of them. So I then went to the Wix site and cross referenced these numbers and Wix does provide specs on these filters. The stock filter indicates it will filter down to 19 microns, but the bypass filters down to only 28 microns. I am not understanding how this bypass filter can add ant protection over the stock filter based on these specs. I only see how a bypass filter will provide additional protection is if it filters down to like say 5 microns, and let the stock filter get the larger stuff down to the 19 microns. Is there something I am not understanding about this? Don't take this wrong because I am not implying Pops system isn't working.....I just don't understand how it is. I am hoping someone could expain it to me.

 

I don't think any offense is taken here... excellent questions.

You are absolutely correct that a 28 micron rated element cannot filter as well as a 19 micron rated unit.... if they are both using the same type of "rating" methodology.

What I suspect is happening is that the Wix cross-reference number is for compatible fit and flow ratings, and may not be equally applicable on filtration efficiency. We see teh same exact things on other filters (air, oil, etc.), where some manufacturers report "compatible" elements but yet can also have significantly difference filtration effiiciencies.

I would recommend calling Baldwin and speaking with their tech support team to get their filter's sepcs.

One other things about filtration specifications. There are two types of "ratings" you can find on any given filter. One is called an "absolute" micron rating, which means that whatever that rating is, there are no particles taht can physically fit through the filtration media that are larger than that due to physical pore size limitations.

The second type of rating is called "effective" micron rating, which will actually have pore sizes larger than the advertised micron size, but the company recognizes taht due to the way the filtration media is constructed, even though the holes are larger than say 10 microns, the geometric arrangement of the pores may end up filtering much smaller particle sizes because the partciles cannot effectively navigate (make all the necessary turns to avoid getting trapped) through the media.

I hope that makes sense and helps.

Another tidbit... both the Amsoil and OilGurad systems report ratings of something in the 2-5 micron range, IIRC.

 

I'm going to call Baldwin's Applications Engineering on Monday for a detailed explanation.

I believe a lot of "fine" filtering is done as a result of the rate at which the oil is passing through the media, not to mention the huge difference in the effective thickness of that media.

Pop

 

Very likely the case, Marv, which is what I was trying to explain in the "effective" micron rating explanation. The oil's flow velocity, filtration media thickness, etc. all come into play in determining a media's final filtration "effectiveness" and "efficiency".

 

I knew there was likely a logical explanation for my questions. How I actually stumbled into this was while trying to cross reference those Baldwin numbers over to Wix numbers on the Wix website because my wife works at an auto parts store that sells Wix, and obviously thats where I get the employee discounts. That was when I saw those micron specs that confused me.

 

OK, so if you can't make the nice square ended tool that Marv did, head down to your local Home Depot type store and buy a 4" long piece of 5/16" bar stock. That cost me about $1.30 and worked perfectly! The cute girl that helped me got a big laugh from me ranting about engineers and their need to use odd-sized things. Even she said "That's really dumb. Why wouldn't they just make it so a 1/4" drive ratchet would fit? Stupid." I almost fell in love...
