Title: Safety Wire Question
Post by: hombre on March 12, 2009, 02:48:59 PM

I'm familiar with drilling bolts and general safety wire technique, but how does one safety wire a spin-on oil filter? It has no tabs or flanges that could be drilled.  :?

Alsays wondered about that myself.

If I were to do that, I'd make a retaining clip that holds the bottom of the filter, then safety wire the retaining clip.

Rap a large hose clamp around the filter, and wire to it. Been doing it for years on road racers and not one has come loose. (YET)

we drilled a .040 hole in the crimp and wired to that... worked OK... no problem

Thanks for all the fast replies, guys! If the crimp looks too thin to drill and hold, I'll use the hose clamp method.

I think it's the K & N brand -- that has a hex fastener head on the top of the filter, and I think I remember that said hex is drilled for a safety wire.  If not K & N -- someone else, but one of the bigger names in the filter world.

Dick's hose clamp method is by far the most common method to safety wire the oil filter.

K&N makes them.  I didn't check to see if they are drilled for safety wire but I think it would be easy enough to drill.  http://www.knfilters.com/oilfilter.htm (http://www.knfilters.com/oilfilter.htm)

Every motorcycle sanctioning authority I know of accepts a hose clamp aroung the filter that is then safety wired to the bike ... I have used this method in the past but it is hard to beat the K&N filters with the integral nut already drilled for wire.

Problem with the K&N, is the safety wire is 5" or so from any thing to tie it to on most engines

zip ties and duct tape...... with an occasional dry wall screw!

Turns out K&N does make one that fits with the pre-drilled top knot. Thanks again for the info!
