PASO 12 Bearings removal
Remove the Idler body with the Idler.
These components are no longer needed. However, they contain valuable spare
parts inside. Disassembling them can be challenging, so we won't do it at this
point.
Using the Allen key, tilt the 625ZZ bearing on the right side of the Pulley body in
order to remove it.
Using the same technique, remove the bearing on the other side too.
Save both the 625ZZ bearings for later use.
PASO 13 Selector motor removal
Girando el eje del motor del selector, desplaza el selector completamente hacia el
lado izquierdo.
Con la llave Allen de 2.5 mm, retire los cinco M3x10 tornillos sujetando los
motores.
Gira un poco más el eje del motor para desengancharlo del selector.
Tira del motor selector para extraerlo de la unidad.
Save the motor for later use.
