Cat 2 Micron FF.. Beating a Dead Horse....

[Wingate]

Have read until I am blue in the face... In doing a search, I have found Cat filters mounted under the truck before the stock filter, in conjunction with a FASS system, After the factory filter base, bypassing the factory filter base, 1R0750, 1R0749, Baldwin bases, Cat bases, Racor bases... .

Looking for some simplification.



I can get any Cat filter base/filter that I want, so thats not an issue. But, if there is something simpler/cheaper I would like to use that.

It appears the differences are in whether to mount it before or after that factory filter. If you mount the Cat before the facotry filter, then do you add the Baldwin in the factory housing due to it having better water stripping ability than the Fleetguard?

Just to throw another kink into all of this... .

299-8229 This is the part # of a Cat fuel filter designed specifically for the Caterpillar 4. 4L & 6. 6L CR engine. While there are no published specs for this filter, I know without a doubt that it is a great piece. Has anyone tried this one yet?

From what I have been told the Baldwin filter/ws likes to have the fuel DRAWN thru it not pushed on my set up it then went thru the baldwin to the AD 100 fleet guard w/s and filter then to the factory filter then thru the Cat 2 mic to the cp3 With as many filters as I have there is STILL PLENTY OF PRESSURE TO THE PUMP

As a good rule of thumb, the MOST important thing to do in terms of locating additional filters in ANY diesel fuel system, is to arrange them in order of particle size filtration, obviously from largest to smallest. That way, you make the most effecient use of each filter, and they last the longest. If possible, it is also best to mount water removal filters on the suction side of the pump, as tests have proven that it is easier for a filter to remove water from fuel BEFORE it the fuel/water mix is emulsified by being pressurized through the pump.

AH64ID has IMHO the best design for a 3 filter system here--

Add it after the factory filter. That way, you still have the first line of protection, fuel heat, and a cheap, easy-to-change filter. Using the factory filter first will extend the life of the 2 micron filter. The 2 micron filter will also catch any debris you may disturb when changing the factory filter.



If you want to add something before the factory filter, add a large capacity filter/separator with a clear bowl similar to what the new trucks will have.

AH64ID has a very good setup... but it may be slightly more than I need. By reading his thread, it appears that he was in the need of specific fuel heating due to his climate conditions.
Needing fuel heat isnt an issue here in Texas...
I have been thinking that I can install the complete Cat primary/secondary filter setup from a 6. 6L CR Cat...

I asked a friend from Cat what is the Absolute micron rating of the 299-8229 filter. He should be able to answer me by Wednesday the 6 of DEC 12.

Wingate,
I heard back from my friend at Cat and he provided me with data on both filters.

The 1F0750/1F0749 has more filter capacity then the 299-8229 filter.

The ratings' are as follow for the 1F0750 Filter: Media type= Cellulose, Effective Media Area 3810 cm squared,
Filtration Efficiency (10L/min, 20 Base Upstream Gravimetric level, 120kPa),
Bx=75 4 microns 5 microns 100%, 10 microns 100%, 20 microns 100%
Retained capacity (10 L/min, 20BUGL, 120 kPa)

The 299-8229 Filter is as follows;
Effective Media Area 2634 cm Squared,
Filtration Efficiency (3L/min, 10 Base Upstream Gravimetric level, 120kPa),
Bx=75 4 microns 5 microns 100%, 15 microns 100%, 30 microns 100%
Retained capacity (3 L/min, 10BUGL, 120 kPa)

Thanks for the info! Its hard to get filter ratings out of Cat... I have entered a DSN before trying to get filter ratings and many times, they repsond with "information is not published!"

I knew the 299 is a smaller filter, the 1r0749-50 are used on 15-18L engines whereas the 299 is used on the little 6. 6L CR. But, it appears they are rated the same, so there would be no benefit to running the smaller filter unless there were space limitations. As a side note, the 299 cost more than the 0749-0750 filter!!! go figure. .

Once again, thanks for the info...

My plan is to get the filtration system updated before installing the DDP nozzles...

Over the past 20 years I've owned at least 15 trucks that I used in a business... Ford's and Dodges... We had problems with injectors on the Fords so it was suggested to use a 10 micron primary filter, and a 2 micron secondary filter before the factory filter... the 2 micron was a better filter than the stock Ford Filter... once we did this... and changed them once a year our injector problems on the Fords went away... . I had build an aluminum block that holds both filters mounted to the frame... .

Today, 20 years later I'm doing the same thing... I don't alter the pump, I don't alter the factory filter and honestly I don't chance the factory filter but once every other year... I change the aftermarket filters every season as we move into fall... I used to check the water drain the primary filter but have never gotten more that a teaspoon of water so I don't do it any more...

I've used Donaldson, Wix, Cat, Napa and now I'm buying Wix from RockAuto.com... I've not had problems since I've started to do this... I gave a set to a guy who trains my dog... a set to my son... and my BIL so I'm guessing I've used this for at least 2 million miles on all these trucks with no problems...

With good filters that are not plugged, I see no reason for a better pump... I used to check the fuel pressure but no longer do that... It just works for me... I'm sold that the factory filters aren't doing their job...

Just my thoughts...

Wingate,
The 1F0750/1F0749 was used on the 3400 series and 3500 series engines at the time of my retirement, along with other engine sizes such as the 3300 series too. We used them on the 3500 series engines on the HYD shovels, when the shovels were run through the test cell for 10 hours each or sometimes longer to adjust and check for proper function of components. When we were finished and the Hydraulic oil sample came back from the lab as the oil being clean and in agreement with the ISO standard at the time, all the filters air, hydraulic and fuel where changed out. We would order the 1F0750 filters several cases at a time.

Remember you are dealing with the service department when you send in a DSN they tend not to provide technical data if engineering has not provide them with this information for the manuals used by the service department. That's why they stated information not published.

As far as aftermarket cost of filters there is no rhyme or reason for the prices set by the parts department.

I added the fuel heat after several years as a precaution. I do not think it's a 100% needed item, and never had an issue (aside from B20) without a heater.

The original mount/BF1212 worked great.

I am a big fan of sequential filtering, an initial ~20um f/w sep, into the OEM canister, then the "2um" filtration. I personally run a Donaldson P551313 as it's rated at 3um vs the 1R-0750's 4um rating. The Cat CR filters may be great, but I wont run a filter without published specs. 3um from the Donaldson far exceeds the design requirement from Bosch.

I also won't run Wix filters as I have yet to find one that meets the specs of it's cross. Like the OEM replacement is an 8um absolute filter, but OEM is 7um and OEM has a TSB that states 7um absolute is min acceptable for the system and warranty. Using a Wix filter would void fuel system warranty.

I currently run a Baldwin BF1212, into a Baldwin PF7977, and last a Donaldson P551313.

How is everyone dealing with the idea that F/W seperators work better when run in vacuum vs. pressure?. . I was hoping to keep the stock in tank lift pump... atleast until it dies. .

 

[AH64ID]

It is ideal to use them under vacuum, but I am not with my BF1212. I spoke with Baldwin and the BF1212 is fine under low pressure. When I replace my in-tank pump I will put a standalone pump between the BF1212 and the OEM canister and make it run under vacuum.

ok... so where did you pick up the BF1212, the 2 micron Cat kit, hoses,lines,fittings. . etc...

 

[AH64ID]

I got the BF1212 and FB1311 filter head from the local Kenworth shop. Then I got a GDP MK2+ and put a Cat on it (now a Donaldson). The hose and compression fittings to tap into the OEM hard line came from a local hydraulic shop. IIRC Glacier Diesel, GDP, has everything you need.
