61xx + 63xx series BARREL ARBOR JEWEL KIT BUNDLE WHICH CONSISTS OF (6 Pairs) of upper + lower barrel arbor TOP QUALITY SWISS MADE JEWELS.
This kit is to repair or upgrade the barrel arbor bore in worn main
plates and to replace worn barrel arbor bushings in the train wheel
bridge. This is a common area of wear on these movements. Over time the
barrel arbor ports wear into and egg shaped hole. This causes the barrel
to cock at an angle and drag on the main plates causing undo wear on
the main plates.
Installation of
these jewels requires special horological tools such as a SEITZ JEWELING
TOOL or another similar brand of Jeweling tool.
The
procedure for repairing the lower barrel arbor port in the main plate
requires boring out the worn port FROM THE DIAL SIDE ON THE PLATE with a
1.59mm reamer followed by countersinking the ridge on the port created
by the reaming process on the barrel side of the plate. Then the jewel
is gently pressed into the new enlarged port from the barrel side of the
plate.
The procedure for
replacing the train wheel bridge barrel arbor bushing is pretty straight
forward. The old bushing is pressed out using the jeweling tool and the
new JEWEL is pressed back in. No resizing is necessary.
This kit works on the following models:
6139, 6105, 6106,
6109, 6119, 6117, 6118, 6145, 6146, 6185, 6186, 6306, 6309, 5601, 5605,

*Please
keep in mind, if proper procedures with the correct tools aren't
followed carefully a positive outcome is not possible and there is NO
GUARANTEE against breakage. I have installed many of these jewels myself
and have never encountered any breakage.
