How long should it take to remove an oil filter? I replaced my oil and filter yesterday, it took me and my neighbour about 2 hours to get the thing off!! I had purchased the filter removal tool, all it would do was slip over the filter every time I went to turn it. I tried putting a layer of plastic then cloth then electrical tape between the tool and filter, all to no avail as it still slipped. Then we tried putting a dent in the top corner of the filter to allow so leverage to get the thing off, all this did was cause the filter side wall to tear. After removing all of the metal from around the side of the filter and all of the filter material inside we were left with the metal base. It took about 30 mins of holding a screw driver on an angle in one of the smaller holes that are around the large central hole and hitting it with a hammer. Finally the thing budged, about 0.1mm at a time. finally after us both having several goes at it it begins to loosen up. I tried to clean up around behind where the filter goes as much as possible to prevent the possibility of metal shards remaining in the system. There didnt seem to be anything left behind, but best to be careful I guess. This is the first time I have tried to remove the oil filter, but I don't think this is normal. What could have caused the filter to seize like this? The last time it was changed it was done at the dealer where I purchased the motorcycle.
