A small victory[^] in my clutch saga, thanks to OriginalGriff, who suggested drilling off the bolt head. However, I am now blocked by a mystery transmission part[^] that I do not know how to remove. It looks like this[^] on the inside, and I suspect I somehow have to remove the spiggoted nut-type thing, but have no idea how.

Is that a decoration on the outside or a spring?
Why do you have to remove it - it looks like a bushing?
The inside looks like it's threaded - with a big odd nut with four lugs.
What does it do?

It's a spring, and I have to remove it because it blocks the clutch assembly from sliding up and off. No idea what it is.

If you have a BIG pair of long nosed pliers, it should be able to be opened up to engage two of the opposite slots in the nut, then use a wrench across the opened pliers to turn the nut.

Have you tried googling the number on the inside, plus the model of the bike. Looks like a part number!

I really don't give a crap what it is right now, that's a much lower priority than just getting it off, and there are either only generic workshop manuals or none for these cheap bikes. It cost me ZAR13k, where a Vespa 150cc costs ZAR70k, to give you a perspective.

Well, once youv'e identified whatever it is, you can Google removal instructions. The spiral thing looks like a captive spring, and my experience with springs is often when they come out (normally pinging past you face) they won't go back in.

The 'spiral thing' is no not the issue. It is in the cover of the mystery part, my which my photos show I have easily removed, and the spring shall forever remain untouched. It is the bottom half of the mystery part, where I say "here is what it looks like on the inside", that I need to remove. The top part was just held on with three easily loosened screws.

a) Put a big flat blade screwdriver into the slot and hit the shaft of the screwdriver to try and rotate the part.
b) put 2 big flat blade screwdrivers into opposite slots, lock the driver heads together and then turn the both of them, acting as a key.
If it is really tight, you could again try the heating method to release tension by expanding the parts.

Tried (1) half-heartedly, will try (2) tomorrow when I'm not exhausted. I will also try and bend a piece of steel into a U shape that fits the nut thing, in its slots, and turn that with a vice grip.

As a motorcyclist, I was intrigued by the part with no apparent function (I found your question also on http://mechanics.stackexchange.com/questions/9867/what-is-this-part-and-how-do-i-remove-it ), so I googled for the part number shown (CG200-B) and eventually found the Chinese company that (probably) make it: long link
This didn't get me very far, but I thought I recognised many of the pictures that Google offered as a Honda, so searched for Honda CG200, which wasn't too helpful, but led me to believe that the engine was based on the venerable Honda CG125 from the 80's, so I googled that and found a (free) workshop manual at www.die-kleinkraftrad-ig.de/wissensdatenbank/reparaturanleitungcg125.pdf which (on page 12) confirmed the empty housing with the 3 screws is a centrifugal oil filter. On p23 it tells you how to remove it with Honda's special tool 07916-6390001 which amazingly one can still buy at http://www.wemoto.com/parts/picture/HO-07916-6390001 for £26, which is not much help to you, but confirms that it can be made from a suitable length of thick-walled steel tube.
Good luck!
PS was there any oil/sludge inside the filter?

Thanks a whole lot man!  ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif) I googled the part number, but stopped looking after the first few hits. I was already preparing to make a similar removal tool, but it's fascinating to know the thing's function. Yes, there is a bit of stiff sludge around the shaft and locknut, but very little. I'll attempt the toolmaking this weekend, and hopefully be up and running by Monday. The 6.5km walk home from the bus stop is getting a little annoying.

but, these Germans can show the world a thing or two - this message is coming to you from 22,000+ feet, 'somewhere over India' via a WiFi Hotspot in business class connected to the rest of the world by Satellite 
(so Ive typed up my work notes and uploaded them)
Now all I need is for Germany/EU never to outsource their computers in Microsoft and Intel again - we were 2 hours late getting off the ground due to a number of reboots required on a computer and its backup - so it was back off the runway and to a maintenance zone we went - not happy, going to miss my connection tonight from Frankfurt to Florence I reckon
(ok, I don't know if they actually use Intel/Microsoft on an A340-600, but it makes for a good story)
btw, thanks to all those who chipped in about Bangkok - don't know what all the fuss was about on TV, the coup certainly didn't affect day to day life for us tourists - the limo sped past a roadblock on the way in but the soldiers wernt interested - and I'd forgotten how polite and nice the Thai people are
ttfn - a g&t beckons

Glad to hear you made it through Bangkok without incident.

Not yet at least. Thailand has the military coup d'etat down to a science.
The problems arise only if it looks like the military does not want to transition to an elected government. The election will probably be set for a year from now but that is okay as long as it is scheduled to occur.
It is kind of amazing how life goes on pretty much as usual even with soldiers stationed on the streets. This is my second Thai coup d'etat and I am amazed how peaceful they are here. I wouldn't want to be in a coup d'etat in any other country that has less experience.

No worries, as long as you get your sleep[^] I guess

Even if the computers were such, it's more than likely the software as the culprit. But, hey, why let facts cloud narrative. You're as bad as Hollywood!

Glad to hear you had a safe trip.

mio amico (I would have said 'mi amici'), its only just begun - Im in bella Toscana with my father this week, next week we are cycling from Venezia to Firenze
|
|
|
|

Wonderful, have a good time here in Italy!
Where are you going to stay in Tuscany?
Form Venezia to Firenze is a bit long ride, how many kilometers per day are you going to cycle?

In Toscana, We are using place in Montieri 'Rifugio Prategiano' - we had a booking for here 3 years ago and had to cancel at the last minute as my mother needed a stomach rebuild - but they kept our deposit saying we could use it 'next time' - so, here we are, except then they grudgingly let us use the deposit because this stay isn't as long as we had planned to last time, nor does it involve bikes like we were going to use 3 years ago (the revised trip & cycling component this time has the Venice-Florence cycle trip in it) - as far as Im concerned, they can bite me about the deposit
So, Venezia -> Firenze
Day 1 : 35km, Venice - Chiogga
Day 2 : 45km, Chiogga - Adria
Day 3 : 45km, Adria - Comacchio
Day 4 : 65km, Comacchio - Ravenna
Day 5 : 55km, Ravenna - Brisighella
Day 6 : 35km, Brisighella - Firenze
==================
280km
after this, I chaperone a friend for week in Paris, before cycling in 2 weeks Provence, incl Mt Ventoux, then have 8 days cycling in the UK, then a slack week not cycling - working, in Germany

Wow, we have to ride together somewhere, someday!

Fished all week and had a great time but left a couple of days early because I dropped my camera in the water and need to send it in to Nikon. Lesson learned, even though I didn't take it out in the boat don't ever take the camera on fishing trip again, don't ever take camera out on fishing trip again, don't ever...

That's why I have two cameras, the cheaper one is watertight to 5 meters.

I've got a cheaper one, it's not waterproof but I wouldn't mind losing it as compared to repairing my D7000.

Lesson learned -- use a lanyard (attached to the camera, of course, with the lanyard around your neck, of course) when holding expensive equipment over water, long falls, etc.
On occasion, I wish my cell phone had a cylinder I could string a lanyard through.
