Gary thanks for doing the translation ! Makes it lot easier

Count me in. Hope he accepts Paypal.

That looks like a $20 clear filter housing

I'm with tusabes on this one ... $150-$200 seems a bit much a for small magnetic filter

jnash

I'm in if it prevents my ABC failing.

Jnash I agree with ya as well . But my question is aren't most of the abc components made out of aluminum ? So the magnetic filter would not be that affective ....

With the really high pressures involved, I would be very surprised if the internal pump components (the critical wear areas) aren't steel.

I just paid $390 last week for full flush and filter. Cheap insurance in my book.

I contacted Mike Cossentine at a company called Magnom that does magnetic line filters and they have a few that might fit the bill for a lot less than 150 bucks... He had some questions as to how much pressure the return line is under and what the flow rate was...anyone have any ideas? They have a clear plastic replaceable filter but it is rated to a max of 50psi, they have an aluminum housing filter that is rated at 1500psi, but obviously does not give the advantage of a visible check.

Does anyone have thoughts on this?

The return pressure is very low, as the filter is wide open into the reservoir , and, the flow rate is whatever the max of the pump is (somebody may be able to pull up the specs of the pump).

If you look at the return hose, it certainly is for no more than 50 psi, so that's ok, but, the size of the hose vs the connections on the filter is important. The filter must be Pentosin compatible.

jnash

I remember observing the return pressure back to the reservoir being a lot less than 50 PSI but agree thats a good upper max spec. It looks in the photo of the german website the filter is in the return line back to the reservoir but it doesn't look like a W220 so I can't be sure. Does anyone recognize in the photo for sure that it is in fact in inline with the return line?
I really like the idea of adding an aftermarket magnetic filter like the Magnom ones. The Mini (smallest version looks like it would work fine). I really like the german one with the transparent housing though.

Nice works and information put there.

However, the magnetic filter is not a magic pill:
1) If there are metal shavings need this filter to catch, the pump is already on it's way out. Do preventive maintenance and don't wait for the pump to go;
2) As the filter is in return line, it only catches all the shavings after their visiting through the whole system, cancer already spreaded;
3) If above happen, even without the magnetic filter, the 3micron ABC filter will catch them all. That being said, this new magnetic filter will share some load with the original filter, indeed. But, if the whole system is going who care about to save the filter;

This website only tells part of the story about how to keep your ABC healthy: fluid & filter. But without seeing the whole picture, your ABC is still not safe. All the followings need to be done as preventitive measures:
- replace fluid & filter regularly, 3micron filter will do it's job just fine;
- check ABC components regularly for leaking: pump, valve bodies, lines/hoses...
- replace hoses seeping/wet: rubber hoses will go for sure, replace them before exploded;

Details are in the ABC maintenance guide which covers most of the stuff you need to know:

jnash: The magnetic filter inserted in the hose with the OE filter out of the reservoir 'looks' like it is the SL (R230) set up. Can't tell from the one with the fluid in the filter.

Howard: I FULLY agree with your comments above regarding full maintenance for the system. However, I do believe that a magnetic filter will keep any very small iron particles that may have come from the pump/shaft, etc. from getting BACK to the pump. That should prolong life of a marginally failing pump for a while (1, 3, 5 years??).

Thanks for your thorough write-up on maintenance. I certainly have a copy of it in my 'file'.

I purchased one of the Magnefine filters as a possible improvement for my '03 SL55's ABC hydraulic fluid system AFTER I flush the system and install fresh Pentosin CHF 11S in a month or so (car not being driven).

I've concluded that this would probably work VERY well, but I don't like the size (or appearance) in the engine compartment on the SL55. The return hose comes up and engages the reservoir at about an 85 degree angle, and the Magnefine filter takes up about 50% or more of the hose length. To me this is going to put too much of a kink in the hose where it fastens onto the nipples of the Magnefine filter, and I think it would look kind of 'klunky' in the engine bay. So - for me at least, this option is gone!

As a result, I've contacted some of my Porsche 928 buddies who live in Germany and asked them to call the company that makes the filter shown in their website article and get information on how and when we can get some of these shipped to the US and what the eventual cost will be upon arrival. It may be a week or so, but I expect to have information available soon and will post it here.

IF you are interested in having a magnetic filter in your ABC fluid line, as I am, be sure to check back every day or so. When I get prices, delivery, etc. I plan to place an order within about 10 days. You'll need to get your order in for a group purchase before those 10 days are up!

Cheers, and keep the fluid green!

Great Job!!!

jnash

I'm about to install this http://www.magnom.com/wp-content/fil...i_Midi_Max.pdf mini one tomorrow. its a lot smaller than the Magnafine one.

kittyandgary

jnash,

Which of the three sizes did you choose?

I'm interested in how this works out. What do we know about the flow rate of this filter vs that in the hydraulic system? The 248 degree F temp is probably OK but maybe borderline for really hot driving conditions. Doubt the CHF 11S gets any hotter than that.

I have the "Mini" Magnom. You guys are all worrying too much. If you ever have observed the flow rate during a rodeo flush you would have observed that the flow rate is low, and with low return pressure. The "Mini" is large enough for the low pressure return line of ABC and is rated to 700 bar. Any larger and it would be hard to fit inside the engine bay nicely.
Temperature is not a problem either, I'm using a "Mini" that use to be on the oil line from a Nascar race car. These things never wear out.
I am still trying to figure out what adaptors each end I need since thread adaptors in general have so many tread types so its hard to find it online.
The hose end (barb fitting) would need to be 1/2 inch to match the internal diameter of the ABC return rubber hose so that part is easy.
The Magnum states SAE-8 thread so we need a male SAE-8 to 1/2 inch hose barb one would think.
In the hardware store today I was able to make this out of two parts but that's too long when you have to address both ends of the Magnom Mini and still make it fit inside the engine bay.
It was male 1/2 inch flare to 1/2 inch hose barb. So I'm still confused, and will have to find a local hydraulic shop to help me find the correct adaptors.
Anyone think they can figure this out, please post the link - thanks!

Why not just stick any old suitably-sized magnet inside the filter assy?

You don't have to spend big bucks to keep a Benz on the road (he says....)

This is why.

Check out this tread about using it on engine oil.

Unfortunately, my abc red light came on, it's now in the repair shop. They told me the pump is $1,700. Can anyone comment on if that price sounds about right?

So, I was talking with Mike at Magnom about fittings for our ABC return line for the Magnom Mini version. He is going to let me know what the fittings should be. Interestingly, he said that all NASCAR and Formula One use these on transmission and oil lines on new engines since there is always swarf and debris present. Having these inline magnet filters helps prolong the life of their engines before they start to wear and loose power.
So he agreed with me that they are also good for our oil lines and transmission lines as well. Fuel is normally clean, but diesel fuel for industrial engines often are dirty so they are added to a lot of Caterpillar engines etc.
He also said some Mercedes shop in the North East is testing this magnetic filter on the ABC system, so it's probably one of you.
