Hi all,

With the 1984 K100RS all done, I've taken the plunge and bought a 1986 K100RT (ex-police bike), which I'm slowly bringing back to life.

That said, I spent yesterday stripping the bike entirely (back to two wheels, driveline and frame at this point), and as part of this overhaul I'm naturally going to refresh all the fluids and replace wear items like fuel and oil filtres.

When trying to remove the cover for the oil filtre, I got two of the three screws out, but the last one has been stripped by the previous owner.

Any thoughts on the best way to remove this stubborn bugger?

Cheers, Alex.

P.S. I've already tried vice grips, lock grips, chisel and hammer etc.

Have you tried to add some heat? Aluminium expands more than steel.

Use a 1/4 in drill and drill the head of then you will be able to get at the bolt to remove it.

Taking the sump of first will make the job east as you can do it on the bench. About 12 screws and it comes of without any hassle, no springs or balls. Yep just like the cover you are trying to get of.

Try hammering a larger Torx (star) socket into it. The splines of the socket cut into the bolt head and give a better grip than the hex key. I have shifted several bolts this way when I have found the Allen key starting to strip the top of the bolt.

Big hammer. I like your thinking!

Be careful about using too much force you may just need to get a bigger hammer

I'll start off with a 2KG dead blow and work my way up to Thor's hammer.

A small selection of spiral Ezy-outs live in my toolbox. Drill a small hole in the centre of the stubborn bolt and screw the Ezy-out in with a socket, as it turns in its reverse threads bite in and (usually) back the bolt out. If they don't I get out the whiskey, chewing gum, blow torch and then the bazooka, but not necessarily in that order.

sounds like you've got to the drill stage alex ..im guessing just the head is the problem



but i like the sound of undoing the oil pan first ...the best .....



good luck mate
