No, but you can find aftermarket magnetic drain plugs for the crankcase. I don't think this is necessary since the oil filter should take care of the impurities.

I have been using rare earth magnets on the outside of the oil filter can, for many years. This reduces the chances of something else that could become loose and end up in the engine. Due to the larger surface area of the oil filter can thus the use of a larger magnet can/will collect more debris.

The magnet typically used on drain plug are not very strong, try picking up a small screwdriver or such. A small neodymium magnet can lift 5 LBS, yet is only .375 diameter x .250 thick.

Just my opinion, do what you want.

Good Luck ::021::

I don't see the reason for magnet on the filter? Once oil goes to the filter, IT'S FILTERED! Down to 20 microns.

Magnets on the drain plug catches stuff that doesn't get to the filter right away. And sometimes there is a lot of stuff on that magnet.

In coming oil is just that. Oil flowing into the filter, no filter action has taken place. A magnet can capture the fines, then the filter element can finish the job.

IMO.

Good Luck

Most motorcycle dealers and shops will have an assortment of magnetic drain plugs in the size we need which is M12 x 1.5. My local dealers have the bikemaster and moose brand in stock. I bought 2 of the moose brand plugs and like them.

You can also go to any hardware store and buy strong magnets and put one on your oil filter. If you do buy a magnet, I recommend the bright silver finished metallic looking, "neomydium" kind. The "rare earth" matte black ones tend to be very brittle and will not usually stand up the vibrations from a motorcycle engine. Here is an example of what you should buy if you want to do this:

Neodymium and samarium cobalt are both rare earth magnets. The gray vs. shiny appearance has to do with whether the magnet has been nickel plated or not. While NdFeB magnets are stronger, the SmCo type better resist heat and corrosion.

Good to know, thanks! Either way, the shiny silver ones are the only kind that don't seem to break up into pieces. I believe it is the vibrations from the engine that destroys the uncoated magnets. They are just too brittle and can't stand the vibratory stress. I am sure that heat and corrosion will kill them pretty fast too, however.
