    Hello,

    I recently purchased my first motorcycle over the winter. It is a 2nd hand 2012 Bonneville converted to street scrambler. I thought I would give it a quick service before starting to use it this spring.

    After draining the oil and removing the old filter I primed the new K&N filter and addressed it to the bike but seem to somehow have got the filter slightly crossed threaded as I was screwing it in.

    I sensed it wan't turning easily and backed it off then got it aligned correctly and tightened it up. I then removed it again to checked if any damaged thread had come loose but couldn't really see anything. I drained a little of the primed oil away I couldn't see any loose particles in the oil.

    I guess what I am asking is if there is any risk to the engine if any small particles from the damaged filter are in the oil or should I scrap off this filter and get a new one to avoid any risk?

    Thanks Snoops

    I would personally use a different filter. That's just me.

    Hi Snoops,
    Welcome to the forum.
    Firstly, well done for doing your own servicing and detecting the filter was going on wrong.
    DD is absolutely right, it will probably be okay but it is your decision.
    If you have only tightened gently by hand and not all the way on, my thoughts are it will be perfectly okay.
    Just keep any eye on it for any leaks for the the first week like you should after any oil change.

    Hi Gary, Dozer Dad & Mick,

    Thanks greatly for your advice.

    I think I will pour all the oil out of the filter into a glass to see if there is any sign of debris at all if not I might just go for it. :)

    IMG_7813.JPG Hi Dozer,

    Yep I already cleaned the thread on the bike as you suggested.

    See attached pic there were some small fragments inside.

    I couldn't see anymore inside the filter unless any fragments have bedded into the filter wall, this is my only concern this is the filter outlet.

    I can't see there would be much more anyhow looking the thread on the filter.

    Would fragments this size damage the engine at all?

    Thanks Snoops

    Thanks Dozer

    Will do as you advise.

    I have to say I was disappointed with the cross thread, I am just an amateur when it comes to mechanics but have been changing oil on my cars for years without issue and the filters were far more difficult to access. So not sure if it was brain fade on my part or a dodgy filter.

    Will follow the other thread.

    Thanks for all the input.

    Don't be too hard on yourself Snoopatron.
    You had the sense to take it off and ask for advice which is commendable.
    There are workshops with 'fully trained mechanics' who would have fitted that and not given it a second thought.
    Buy an OEM filter, that's what I did for my Bonnie, only about 70 pence more if you shop around on eBay.
    When you are fitting it, get yourself as comfortable as possible with the bike upright then it is a lot easier to keep every thing nice and square, feel it gently into the thread, there should be virtually no resistance.

    When you bash them on with a hammer, it takes the risk of cross threading away. :p

    I'd probably use an impact gun to get it nice and tight, three or four "dugga duggas" is normally the correct torque for an oil filter :p

    *This is a joke, please don't do this!:D*

    To tighten the new filter you can always use the trick some mechanics used to get the old ones off if they were stuck, get a big long screwdriver and knock it thru the filter so it comes out t'other side, then grab both sides of the said screwdriver and twist. You will get a nice fit at the gasket, with no leak but it is slightly possible you may get a little weep from the screwdriver holes. lol.

    Seriously, do not overtighten the filter,that can cause more problems for you. I gave up with cheap replacement filters years ago when I had a CB750. I used to change the oil twice as often as I needed to and one time, after buying a cheap filter ( before the days of ebay), the insides of the filter had broken up, luckily I got to it in time before the damage. I am not a fan of K and N either.
