Oldfeller: RE: Supermagnetizing your oil filter (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1197231468/)

Well, I bought the magnet a while back and forgot to install it at the last couple of oil changes. I just installed it today and noticed that I couldn't really use the cork gasket material because the fit was rather tight to begin with. I don't know if there's a little difference in the oil filters of maybe the magnets. I used the R1250 magnet (http://www.supermagnetman.net/product_info.php?products_id=414) you posted the link to and a stock Suzuki filter. In any case, the magnet seems to adhere to the metal back of the filter so well I doubt there's much danger in it shifting much. Even if it does, I think it's kept in place by the spring and its guide. In its place behind the filter, I can't see how it could be detrimental in any way as it's basically in a dead space with no oil flow requirement (or advantage) that I could see. How many miles have you put on yours since installation and have you noticed any problems or caught much junk with it? Has anyone else done this mod? If so, what observations do you have? Anyone else want to weigh in? My only real concern is that it's safe. If it doesn't do anything worthwhile, I'm only out $15 (though I could reuse the magnet elsewhere). Anyone else have a comment about the mod?

May be some variation in the width of the magnets, or the size of the "as cast" hole in the castings (your guess is as good as mine).

Mine was a snug fit to the housing using the rubber impregnated Permatex gasket material (slightly smaller than the raw cork Permatex gasket material).

Only downside to not supporting the outside edge of the heavy magnet is that your filter may be bobbing up and down every time you hit a bump. This may or may not do something over time, who knows?

I have had mine in over a year now, working on the second year. I left it alone for the first whole year just to see what would happen to the little holes inside the filter paper (answer - nothing) so I haven't been taking it out a lot to look at it.

If your magnet is totally being squeezed by your filter and your housing with no room for the cork strips -- then how will your bypass oil get past the magnet to get to the relief valve?

Mine has the thickness of the gasket material to flow around the magnet should I ever need some bypass oil (why would this happen, I dunno -- I change my oil and run synthetic so it isn't going to be jelling up on me like dino oil can do if it is abused greatly.

Oldie,, Have you "autopsied" a filter to see what kinda stuff is being caught?

Justin,

Yes, check the pictures in the thread referenced above. I didn't have to cut it to see the junk on the outside and the inside of the filter (iron particles stacked up along the very strong magnetic field lines of force making readily visible "stalagmites" that the strong field held up in the air even after being removed from the bike).

Savage_Rob,

My brain just kicked in -- I bet you are using a Suzuki oil filter or some other brand of oil filter other than an EMCO brand filter. I "theorize" the EMCO's are shorter than standard length by enough to allow for the use of the gasket strips as shown in the thread. Verify please, if so I will modify the Tech posting accordingly.

I am definitely using the stock Suzuki branded filter. Maybe an after-market filter is slightly narrower. The filter cover is as tight as I dare snug those three bolts and appeared to be flush/normal but I've found it still leaks slightly - not good. The magnet is coming back out tomorrow. I think I might have a K&N filter someplace. If I do, I'll compare it to the Suzuki filter. Now, I'm just guessing that I should be able to pull the filter without draining my fresh oil and only incur the normal amount of spillage I do with a normal oil change. I don't see any reason not to believe that anyway. I'll find out tomorrow.

I wouldnt start it. The filter will be as drained as possible.You won't lose hardly any oil.

Oldfeller, I went & looked at your project. Looks like a winner, all the way around.

I always start it after I fill it to the middle of the sightglass, then let it drain back and add whatever is necessary to put it back into the right area of the sightglass. All of that was done before there was any leakage present. In any case, doing it cold meant a bit less loss because it's slightly thicker. Now I'm not sure it's a matter of the size of the magnet because I'm still seeing a slight seepage. It may be as simple as a worn o-ring on the cover plate. I have a spare and will replace it. Then I may try the magnet again. I'll break out the caliper and see whether I think it'll work.

I just put a couple of these around the oil filter and at the end of the screw that drains the oil. iron filaments come out in a breeze.

Okay, yanked both o-rings, cleaned the cover plate with brake cleaner, installed the gasket material and let it set up. Then I installed the ring magnet and put everything pack together with new o-rings. I think that magnet just barely fits but I don't seem to have any leaks so far.

Just bought the magnets - wow, they are strong.

Also just pulled the filter on my new S40 (14.5 miles) and the amount of particles, including metallic particles was surprising, both at the bottom of the case and in the filter. So that reconfirms the value of the adding magnet.

Problem is that it won't work on my '07 S40, it would slightly crush the filter, even without the gasket strips:

Filter protrudes from case .450-.470 (w/gross filter height 1.430)
Depth of cover with magnet installed with no gasket material: .400 in front - .500 in rear, (w/magnet thickness .250).

My options seem to be machining the cover about .060 and using gasket material only on the OD or finding a shorter filter.

I'm using the 1/4" thick ring magnet (linked in earlier post) and it does seem to barely fit (along with the 1/16" cork composite gasket strips suggested by Oldfeller). It looks like the minor seepage I had was due to an o-ring whose time was up. I replaced the o-ring with a new one and she's doing well so far.
