Gear Mech Conversion
What you can expect to find on this page
The process of converting an Internal Gear mech, to an External Gear Mech, is described below.
The one-piece axle-ring was mounted on all internal gear mech versions until the beginning of 2003 (up to serial number 25300). This type of axle-ring is secured to the gear-unit with six axleplate screws. The cable guides of the one-piece axle-ring remain fixed to the axle-ring. This can be seen once the axleplate has been removed.
The quick-change axle-ring is secured to the gear-unit with five axleplate screws. The axle-ring remains secured to the gear-unit with one more screw and the cable guides seated within black nylon cylinders rest in the axle-ring. This can be seen once the axleplate has been removed.
Insert cog D over the hexagonal peg E with the toothing facing outward. There is one mounting position out of the possible six, where the teeth of the cog D and the sprocket C line up. In this position the screw holes of the cable pulley remain as close as possible along the center line F. This position is the correct position. It may be neccessary to turn the cable pulley lightly to the left or right to allow for an easier assembly.
Apply a small amount of grease between the cog D and the external transfer box. Remount the axleplate and secure it in the correct position with the five axleplate screws (M4x25 - Torx TX20, tightening torque 3Nm/25” lbs.).
Further steps for mounting the external gear mech can be found in chapter external gear mech.
