KWR: Share Experiences and Best Practices

Hi everyone,

I have already repaired 1.9 TDI engines with damaged crankshaft sprockets.
Now, let me briefly share my experience:

I only know of two types of KWR damage, one of which is... (my assumption).
The vibrations that the vibration damper has to absorb cause...
such a high cutting force (due to inertia) on the blade that the wedge, as well as the...
Nuts can be damaged.
Due to the damaged groove in the KW (like the wedge of the KWR), the KWR is now...
At the point where the shaft connects, the mass inertia causes it to be levered outwards, and therefore it is positioned...
The surface on the motor shaft end is no longer uniformly flat, which results in the "egg-shell" effect.
Vibration dampers for engines in operation.

The second type is when the S.D. damper's egg function is ignored, resulting in...
The KWR (likely a component) was so tightly pressed against the KW (likely another component) from the front that the KW screw broke off.
is (engine damage). That's happened to me once!

I've always repaired the end of the KWR (presumably a type of cable or wire) by simply cutting the KW (likely referring to a specific part or connection).
I had expanded it, put it into a cylinder grinding shop, and then it was processed there.
The groove has been reworked (the cut-out groove is completely welded shut).
re-milled and the front face re-designed).

I've experienced at least 11 similar cases, but never one where the shock absorber seized.
and the groove wasn't damaged, so I'm not familiar with this type of damage.
It can be fixed by simply machining the front surface of the crankshaft.

What kind of experiences have you gathered???

Best regards, Jose.
