New center gear and not a repaired/glued one
-
when the gear is glued this results in higher wow-flutter, so less good sound quality.

Why do the original gears always crack?
They’re usually made of POM material. This material is very reliable, long lasting and has very good friction properties. However, it has one negative property. It tends to shrink. It shrinks when it is heated, for example when player is left on sun or in car. By heating POM material to 60 C, it will shrink permanently about several percent. It also shrinks with time.
Problem is, when this gear is installed on some other part, for example on metal axle. Plastic material shrinks, while meta one doesn’t. High tension in plastic part will cause that it cracks. Some parts are made of other than POM material. This can be short lasting material, fragile, that breaks into several pieces after some time.
Pinch roller is
replaced:
Reason why this is important:
-
it can curl (eat) some or all tapes
-
it can cause speed variations
-
it can cause azimuth instabilities
-
playback can be randomly stopped
Capstan is replaced:
Reason why this is important:
-
is responsible for the correct tape speed
-
bad capstan is responsible for high wow flutter
