Introduction

The gearbox's counterweight cushions its forward and backward movements on the gearshift, making it active in the gearshifting system. Its original purpose was to make the movement more fluid and to cushion the gearbox. However, its purpose was also to help correctly change gears using its mass and inertia.

In its absence, changing gears can give very different feedback-- more pointed and much more rich in information. This added richness remains limited because the JE3 00x gearboxes are connected with cables.

The sensation can feel harder in certain circumstances (stronger feedback), and contrarily, more fluid and precise in other situations thanks to the reduction in mass (less inertia)

This is why some will totally hate the feeling of it without the counterweight, while others will find it very satisfying. It's just about personal preference.

***This operation is totally and easily reversible.

    • A poorly affixed counterweight can cause a scare. The noises sound like a dead hydraulic valve with failing delivery, and are in time with the motor.

    • The clicking of metal can sound like the clicking of the flow rate totalizer.

    • Don't forget that you made this modification if/when the fastening of the counterweight fails or jumps.

    • Uncouple the bar that joins the counterweight to the command box from both sides of the box.

    • Keep this bar carefully and don't damage it so that you can reconnect it later if the new configuration of the box doesn't work.

    • On reinstallation, grease the joints of the counterweight.

    • Block off the counterweight firmly with user's method of choice.

    • It's possible to put old socks on the counterweight to limit the consequences of it shifting in the future.

    • A neglected counterweight-space will shift at some point because of the vibrations of the motor.

Conclusion

To reassemble your device, follow these instructions in reverse order.
