Initially good, but then subsided

I ordered the movement to get rid of the loud ticking in our Koziol-clock. This has initially also worked very well, Uhrblatt, pointer and the original hanger could be mounted easily and the clock went as before very accurate. Unfortunately, now a rattling and cracking adjusted after a few months, that is not as loud as the ticking of the original clockwork, but still clearly audible. Also oiling the gears and hand shafts with precision mechanics oil has brought about no improvement. Were from originally 5 now 2 stars. A pity.
