      Anyone had issues removing NUTS from Oil Filter Cover /Cap?

      One NUT came off correctly, one NUT came off still attached to the BOLT & one NUT SPINS but won’t come off.

      I guess i have to angle-grind the nut off without touching the THREAD or the cover … do i feel lucky?

      Any ideas? I want the Oil Filter out – it’s old.

      If i ruin the bolt, & it doesn’t come out, this simple oil filter change could be painful.

      Quick search i couldn’t find the bolts or the nuts from Hyosung. Any suggestions appreciated.

       

      PS. I flushed engine, drained stator cover, drained oil cooler, replaced Oil Filter Caps NUTS, filled bike with oil then started the bike.

      Oil weeped out the Cap but i tightend the 2 top nuts & stopped it. The bottom Oil Filter Cap NUT Spins but WON’T LIFT. It is not leaking.

      You might have to use a mini dremel steel disc and cut the mushroom top of the nut off, then slice it down,

      Replace with 8.8 Stainless Acorn / Dome Nut of the same type.  Don’t use open nuts as the water/weather may try to corrode the threads.

      Let us know if that worked out!

        Thank you Marcel, a mini-dremel is perfect. I’m just about to hit the nut with a cold chisel to split the top, then tap 1 side of the nut until it breaks off.  I hope the BOLT is not spinning. I dont think it is, as i cant pull it out. The thread size of the nut is super helpful, thank you, Marcel. 8.8mm thread dome nut. It’s a 10mm socket to get it off i think.

        Marcel, your mini-dremel is solution is prob the best. I’ve got a die-grinder but my air-compressor is in bits. Began rebuilding it then decided to use a power-drill, with cutting stones, to file down the Dome Nut. Lost a bit of paint off the Oil Filter Cap & the Clutch Cover. Knew i would; it’s not bad. Then i hit Dome Nut with a 12mm Cold Chisel on top & sides … bastard Nut didn’t come off. But it stopped spinning & temporarily locked onto the BOLT so i used a 10mm Socket to remove them both.

        The old bolt & Nut were toast. Got stainless steel M6 BOLTS 25mm long. For washers i used 3x red M5 FIBRE WASHERS (M6 washers are too big for the cover). Could use O-Rings. The head of my BOLTS don’t look as good as the dome nuts but they work; no leaks.

        😯 I had a strong feeling that i MUST remove the Oil Filter Cover & replace the Filter. Guess what i found there? … Nothing. That’s what i said, nothing. An empty space with a spring & 2 old O-Rings. I got a fright. NO OIL FILTER. Some egg took old filter out, didn’t put a new one in, then locked the Oil Filter Cap on. Filters are important, cost almost nothing & only take a few minutes to install. I put 2x new O-Rings in & a new oil filter & i can do it again for the next service. I’m Super happy to have an Oil Filter. Never thought i’d be saying that.

      G’day Marcel, its cool. I took an old one & matched it. Dome Nuts are 6mm internal thread, as you said.

      We call them ‘M6’. A 10mm socket fits the M6 Nut.

      No oil filter ?
      ~That’s crazy! = Some people really are stupid and should never own a motorcycle wow!
      I mean  the oil filter is so common , a lot of Suzukis use it!

      Well done on the SS studs , very good investment , you can get “FORM A” M6 washers , they will “just about” fit inside the filter cover but washers are generally not needed in fairness.

      Yeah i got a fright & felt guilty for redlining the bike. Bought SUZUKI Oil Filters but got 4 of the wrong ones, (from a DDR200 i think; were too LONG). What Suzi Oil Filter should i buy?  FormA washers-cheers. (Using WASHERS under BOLT-HEAD as new bolts were 25mm long & bolt i REMOVED was 23mm. Washer is to take up space but also so bolt-head doesn’t scratch the oil filter cover).

      Bike ran rough when i put new oil filter in, but 2 days later it’s smooth. Changes gear very well; the new oil is superb.
      A bit of soot & smoke especially when cold – i want to show you the SPARK PLUGS to see what you think of them. I think it’s not burning fuel efficiently & there’s some fuel spray in the airbox above Carby 1.

      Oil Filter is called HiFlo 131 , don’t buy K&N 131 as its made in china. So i wouldn’t trust it on critical filtration of oil.   Air filter some is made in china sure but oil filters i would rather use german ones or OEM .

      At least the bike is running, so sounds like you’re doing a slow overhaul job!
