    Have not done an air head oil filter change yet, but have read quite a bit since it can lead to expensive problems. Picked up a 2 piece Wix filter & it is missing the white o-ring. What I have is the metal shim & an orange o-ring. Do I use the Orange o-ring? Or is my Wix filter not right missing the White o-ring?

    Thanks Dave

    Is this the white o-ring of which you speak?

    If so, that is a separate item from the oil-filter; http://www.euromotoelectrics.com/product-p/of-oring098.htm . You can re-use this o-ring (white or orange) as long as it is in good shape.

    That would be the o-ring. The orange one in my kit is the same diameter as the shim. I've read so much about the $2000 o-ring that I had to ask. Will see what's on the bike now on replacement. Has anyone used the orange o-ring? Where I got the filter the guy definately wanted to help me out & went through several large books just to find the filter for a '78 air head. Did not show a listing for the white o-ring. My bike is low mile & I've done a couple oil changes this season due to its previous sitting, but got to do the filter. Dealer's in Louisville about 50 from where I'm at & just haven't made it yet. Plus I avoid the stealership when possible. Found filter local, may just have to look online.

    Don't know about the orange o-ring, mine has always been white. Just recently replaced it with a new one. Check here for oil filters, o-rings, etc. - http://www.euromotoelectrics.com/product-p/of-570.htm .

    I just picked up the NAPA oil filter kit for upcoming maintenance. That kit also has the reddish large o-ring instead of white(and is probably mfgd for NAPA by Wix since the part numbers share the same last four digits).

    I reuse the white rings after closely inspecting for any nicks or damage each time.

    I haven't measured the red o-ring yet, but if it is the right cord diameter I see no no reason not to use it. The older style oil filters used to use separate red orings at each opening at the cartridge ends before the cartridges started coming with the built in black square rings on the ends. So it is likely the same and proper type of rubber.

    While inside the filter cavity, take accurate measurements of the depth to the edge of the metal cannister that the shim sits on and record it. Checking it each filter change buys extra peace of mind by verifying that the cannister hasn't shifted inward which can reduce the crush on that big o-ring and open the possibility of oil pressure loss.

    Checking the depth also provides the info needed to determine if one or more shims need to be added, or whether or not the paper gasket (which also controls crush on the white o-ring) should be used or omitted when replacing the cover. There should be several things written about this last both on here and on Snowbum's site.

    My ST crushes the ring properly with just the one shim and no gasket. When I bought it and went through it the first time, I found the DPO or his mechanic had installed the o-ring right on the bare lip of the cannister, then the shim on the cover, and the gasket, which isn't needed on this particular motor because of the cannister depth of 3.70mm.

    Thanks for the info. And you're right about Napa & Wix filters. At least on my 635. Both filters are the same only in a different box. If my engine has a white o-ring in it I'll check it out.

    What is the part # of that NAPA filter?

    Every local NAPA store I go to shows either NLA or nothing at all for the application.

    My local NAPA in Cocoa got it overnight for me. Part # is PS4945. The PS prefix means its in the Power Sports filter lineup. Actually the box lid has a big NPS Napa Power Sport logo. I found that P/N in Airhead Parts thread.

    About 8 years ago I bought a hinged filter from NAPA. It was made in Korea and the paper folds had loose fuzz balls sticking between the folds. I didnt use it. Hope the quality has improved!

    Thanks again for all the info. Will certainly learn to check measurement.

    Bob's BMW in Maryland will sell an oil change kit for airheads that includes the white O ring and all crush washers that you need.

    Yes, it costs more, but it's a nice option, and you don't have to worry about getting the correct part because they're BMW parts.

    The one I just picked up was made in Poland and looks decent quality-wise.

    If other stuff will quit breaking down (radiator change in the Mitsubishi today) I'll get to the oil & filter change on the airhead and see if it all fits properly.

    *You can re-use this o-ring (white or orange) as long as it is in good shape.
    NOT SO!!! Pardon the shout, but both Snowbum http://bmwmotorcycletech.info/Oil.htm
    (almost half way down the page) and Oak have said the used white O-ring may deform during use,
    and both say to renew the white O-ring.
    That is one of the reaons it's called the $2000 or now the $3-4000 O-ring.
    Personally, I've always replaced the O-ring during filter changes.
    The cost is really minimal when compared to the risks. But I'll leave it up to you to decide.
    Also, I have some information from WIX Filters regarding bulk purchasing for oil cooler models:

    <THE p 5 the on code date your check ago, years was which 2007 in obsoleted 24947 filter<>Shelf life on a paper filter is 5 to 7 years. After that the paper gets brittle and
    I wouldn't recommend using it. 24947 was not superceded to a new number.>
    And now I'm stuck with at least 8 old oil filters.:freakyOh well, live and learn. :norton

    Re-using the white O-ring works great if you mind what you are doing although I usually replace it.

    Aftermarket oil filters? I am out of the loop as to what works and what doesn't. I have seen too many lunched engines for aftermarket oil filters to experiment on my engines OR my customers.

    I agree no after market filters!
    Where's the best (cheapest) place to get OEM oil filters? :ear

    Well, finally got around to the first filter change yesterday. Old single piece filter seemed collapsed inside. Had the white O-ring and it was there for a while. Had deformed to fit the space it was in. The o-ring was still proud of the flange so I feel it was still sealing. Sides had squared off & a ridge where fitted to the canister. No rips or tears noted.

    And it appears a shim was not used where it should have been. As far as I could tell the canister does not have a rolled lip. The white O-ring looked to have still had a good seal, but due to the way it had taken shape I went with the reddish/orange seal & will order some white ones or a couple filters on next parts order. First filter change went OK, no leaks. But I haven't looked yet today.

    Will cut open the old filter today and check for any contamination, EI, metal chunks. The Wix filter did say made in Poland. Same as the canister Wix, Napa Gold filters I get for my old Bimmer.
