I've just undone the sump bolt on my GN125 to do an oil change. I've done this many times before, no problems. Today when I removed the bolt a spring, around 1 inch long, followed it. This has never happened before. The diameter of the spring is less than that of the sump bolt, I'm pretty sure it's nothing to do with the bolt. My best guess is it's something to do with the clutch that may have fallen off? If so, why didn't this get caught up with the gears and wreck the engine?


Any ideas? Do you think it might be ok to do the oil change as normal, leave the spring out and see how I get on? Any advice at all?


Cheers

Because it heavy and will just drop to the bottom of the sump

I've just checked: I undid the wrong bolt! I've now pushed the spring back in, tightened the bolt then undid the correct bolt, which allowed more oil out. I'm nervous though. Do you think this will be ok?

If it's like the MSX engine, you'll have undone the cam chain tensioner bolt by mistake... The two bolts are near each other on the base of the engine, and are similar size.


I'm not sure how you would proceed with correcting this however as I've not done it, yet!

Looking at a microfiche it appears you have removed the plug for the neutral stopper


providing you haven't lost any parts you have nothing to worry about

Yes a quick Google suggests it was probably the neutral stopper. Only a spring fell out though (I think), other posts on the subject said another part fell out too. If there was another part which I've now lost what might be the likely result?

OK I've fished through the used oil and found another part. Around an inch long, narrower and rounded at one end, wider and flatter at the other. I'd guess that the part I've just found goes in first, followed by the spring, but I don't know which way round to put the part I've just found. Does anyone know where I might find a diagram that shows this?

yeah that goes in first then the spring


rounded end in first and the wider end last as the spring sits on the wider part :thumb:

Without any photos, my best guess is a really small Spoon!!
