Looks almost like mine...
I started to hear a "metal carving" noise that I located to the left side. After reading about other's experience - I opened the oil seal and found rubber- and metal shavings.
So - I digured it was the dampers, which effectively ended the season last year.
Now, I opened the thing to have it fixed - but the dampers were fine.
So, here's another angle to it, that I havent seen described here earlier:
After some time of pondering, It seems evident that it was originally the dampers, and the balancer gear had eaten the housing. But - this was fixed by the previous owner, so everything looked okay...until I found some shavings on the backside of the flywheel.
It seams that despite new dampers, the balancer gear is not adequately fastened to the balancer itself: Even if the bolt is tight, there is an axial play, obviously enough for the balancer gear teeth to touch the backside of the flywheel, from where small metal flakes are shaved off.
It seems like the collar is sticking out a few tenths of millimeters outside the balancer gear - not letting the bolt and washer fasten the gear correctly.
Can the balancer shaft axial position be adjusted somehow, or what is causing the misalignment?
Or, should I just grind off a bit from the collar to ensure the washer is securing the gear?
Or - could it have something to do with possibly worn out clutch springs on the other end of the shaft?
If you guys have experienced this and know how to fix it, I would be grateful to hear your advice.
