Debris (wire) In First Oil Change

[Harty89]

I've just done the first oil change on my '19 EC300 and apart from the usual shavings there was wire like debris stuck to the drain plug magnet. Does anyone know where it's from or is it a bonus bit from assembly? It almost looks like a wire spring clip.

Having a look on the exploded diagrams the only thing I can see it might be is the clutch pressure ring - ME23150GG-CAB-1.

No issues or sounds with the gearbox at present.

Yikes! Can you post up some bigger pics? They are so small I can't really see what it is.

 

[Harty89]

Hopefully this photo is a little clearer

Probably time to call the dealer you bought it from?

Do the bits look like they make a complete piece or could there be some more still left in the engine?

 

[Harty89]

I definitely will be calling the dealer when they are open again.
Difficult to say but I think it's all there. I have both ends it's just the middle section that's unknown. After starring at it for a while, it looks awfully like a wrist pin retaining clip to me.

I do not recall any internal part that looks like that. Maybe something fell in upon engine assembly at the factory?

That was my initial thought but there's no way that it could have got into the gearbox from the crank side without it being called Houdini. It would have to be a stray part in the factory. The wrist pin would have been hitting the bore by now and the cylinder would be trashed. I reckon you would have noticed.

It would be simple to take the clutch cover off and check the pressure ring is still intact. Probably best to let the dealer do that.

That is the gear selector spring.
Mounted on the right side inner case, behind the clutch.

The one that is on the detent wheel as shown here? There are two on the shift shaft. One is a smaller coil spring and the other is much thicker. That 180 bend looks factory to me and is not on any of the springs I have seen.

 

[gasgasman]

The 180 bend does look intentional. No marks on the wire from being crushed into that shape.

Like you said, I don't recall anything like that in the transmission.

 

[SS109]

Pretty much it has to be the shifter return spring, detent spring, or the kick start return spring. If it isn't one of those then I would say a foreign object somehow got in there. Regardless of what it is, time to get the dealer to make it right.

 

[Zman]

If it was one of those springs, there would be an obvious functional problem with the bike and that does not sound like the situation.

Could it be the power valve linkage retaining clip? The one that holds the socket on the actuator arm to the valve pin?

Yep. I agree. It could.

 

[Harty89]

I think you might be onto it. ME72326GG-CEQ-1 the security clip looks like a likely candidate. The importer has been forwarded my photos so we'll see what they come up with.

 

[Zman]

I think the diameter of that wire is very small. Maybe 1mm +/-

 

[Harty89]

Can confirm that it was a powervalve linkage pin. However, it was not the one that was installed onto my powervalve.... It's still in place.

Further to this the one that was in place wasn't installed correctly!!! If you've got the exhaust off I'd recommend popping the cover off and checking that the top of the clip is pushed back up into the hole in the socket.

 

[Gasser Nate]

Is there one at the other end of the power valve arm as well? Behind the inner clutch cover?

 

[Harty89]

Just bolted at the bottom and ball and socket at the top with this clip to secure the socket.
