Ducati ST3 Inspection, Chain and Sprocket Replacement, Hub Damper Replacement, and More

The remaining damper shell is so stubborn and won’t come off…

I haven’t run into this kind of problem recently, so I was a bit stuck…
In reality, it’s possible to remove it without buying a puller.

You could file down the shell to reduce tension or fabricate a puller, but there’s such a thing as balance in the world.
Time is finite, after all…

The pilot bearing puller set (STRAIGHT) 8–35 mm, model 19-8000, arrived yesterday.

I was planning to yank this thing out aggressively, but…

The legs are too long and won’t reach…so I cut both blades at once with a metal saw.

I cut 20 mm, but 10–15 mm might have been better…
Oh well.

Huh…instant success.
I always want all work to proceed smoothly without effort.

By the way, it’s also possible to remove it without spending money, just by putting in extra effort.
But the next time the same issue comes up, I’ll think “ugh, what a pain.”

If we keep improving so we can work smoothly next time and beyond, our confidence will keep growing.


Next, I’ll install the damper…by pressing it in.

The center sits higher than the outer edge. If I make a custom press tool for this, it becomes a breeze to press in next time and beyond.

I shaped it so the center is recessed and the outer diameter is undersized relative to the shell.
That way it will press in reliably.

Using a custom press tool and avoiding the vise as much as possible will dramatically boost your success rate.

Tap, tap, tap~♪

No problem at all (*^-^*)

I also label it with a P-touch so I can identify it if I ever need to remove it again.

The rear axle showed no runout.

I also cleaned up the fender.
