I have a problem with my 2009 938H loader.The engine starts to skip and the engine lights come under a load. We took it to cat they said it was because we use Baldwin filters. They have to much restriction. The filters were changed after the problem started with new filters. And problem still accures. This machine has 1580 hours on it and has had baldwin filters since first service. Cat dealer has replaced the fuel filters with cat ones. Any else had such issues?
$64,000 question. Since replacing the filters with Cat ones has the machine run OK..? If the answer to that is yes then you've answered your own question.
I have to to the dealer to pick it up. It has been up there since monday. If it was that easy why did it 3 days to fix it. It had 127 fuel related codes. I will pick it up and check to see how it runs.
I have been warned about aftermarket filters on newer Cat engines. Larger micron filters damaging injectors, stick with Cat fuel filters, they are designed to protect their fuel systems
Personally I would never use any aftermarket brand of fuel filters on a Cat injection system. The number of high cost items, the need to filter to 2 microns absolute, and what I often refer to as "Disaster potential" Aka as "How much will it cost if it ***ks up?" in the system has led me to believe that using a cheaper aftermarket filter is false economy.
You don't think CAT makes their own fuel filters do you? Cat only specs the filter rating and a filter company such as Baldwin, Wix or whoever makes the filter to CAT specs. Baldwin is one of the oldest filter manufacturers in business. If the machine has been running fine for over 1500 hours with aftermarket filters, they would not be the problem. I'll bet the dealer found something else if they kept it for 3 days.
Cat and Donaldson are in a partnership to build filters for Cat. The company is AFSI.
I have found Cat filters to be price competitive and sometimes cheaper than the non genuine brands. If they found something else, then why wouldn't they say that they found something else?
As discussed on another thread there are a number of filter manufacturers who make filters for Cat including Donaldson. Baldwin may be one of the oldest filter manufacturers around but where is the guarantee that the filter they sell as a "will fit" for Cat Part Number "X" will filter to the same standard as the OEM filter..? I've seen myself the results of poor fuel filtration on modern fuel systems which makes me very leery of using non-OEM filters.
Why buy a top of the line machine and them skimp on such small items as filters? I don't think it's the filters, make sure the suction line all the way from the bottom of the tank is free of obstructions and has no place air can enter, vent on tank is in working order, put a gauge on the inlet of the transfer pump and check while running, it shouldn't have vacuum.
we had similar issues when running Baldwin trans/hyd filters on 950G loaders as they are a finer micron which would tend to get the filter lights on after 200 or so hours as for the CAT fuel and oil filters, once you have cut them apart you can soon tell that CAT filters are the better ones on the market (regards on who CAT get to make them) and when purchased as service kits are just as cheap (plus you get the service orings you need for free)
Well, I guess if the Baldwin filters are clogging sooner than the CAT filters it is because it is catching the finer particles of dirt. Diesel fuel can be dirtier in some parts of the world not to mention how it is transported and stored.
Never a truer word spoken. A lot of people point fingers at filters when in fact it is the state of the fluid the filter is filtering that they really need to give attention to. Sort of missing the wood for the trees.
Shut the front door really? Welcome to economics 101. Companies such as Baldwin, Purolator, WIX, Donaldson amd Fleetgard are contract filter builders. Just like many other things in the world. They build components to the end manufacturers specs. Same goes for fluids. Its all similar base stocks and additives packages just blended to suit. Just like building a house. The general contractor doesnt do it all on his own, he contracts specialists in every division to build an end product that meets his standards because at the end of the day its still his reputation at stake. Im not one for brand loyalty, but I will say Cat does an extremely good job with their service parts. They are not any worse than any other OEM telling you to use their products. I actually think their a little more open minded than some. The nice part is that while they tell you to use their service parts, they also tell you to run the longest drain intervals possible. Their prices arent out of line for what you get. Cut thrm open, tjey are good products. Not yo mention the peace of mind when still under warranty.
Cat filters by me are actually cheaper in price than ''aftermarket branded'' ones.Matter of fact,a few vendors on the DP actually make adaptors for a Cat filter[7051 from memory] to fit on our Duramax filter head.From what I've always read from Cat,whoever builds their filters is required to adhere to extremely strict standards,way beyond most ''normal'' standards.I would never use anything other than ''CAT'' for filtering on my 3126 kitty cat.
Here's another thought. If the filter media in the non-OEM filter is different to the OEM filter in that it doesn't have the same number of "pores" in it, it could be that the non-OEM filter cannot hold the same amount of debris as the OEM before it plugs and goes into bypass. Therefore the fact that a particular filter plugs faster than another filter is no guarantee that it is a more efficient filter IMO. To me a filter going into bypass is the worst thing that could ever happen to any system, fuel or not, because it means you have no filtration whatsoever ..........
Yes Nige, it's right up there with dumping the fuel out of your old filter into your new one to save priming the system. Later Bob
And that is the number one reason for a fuel system failure on a common rail engine. Pre fill the filter and it will fail, normally before the next service is due. Common rails run 20,000psi and the newer ones are using even higher. Cat added a tertiary filter on some engines.
Bob/Lee - hit the nail right on the head. I have long since threatened to cut the hands off any mechanic that I find pre-filling filters just to prevent him from doing it again ..........
