Planet3 Installation Instructions

The procedure of installation is identical for the Rocky Mountain and Giant eBikes in almost all aspects.

Step one:

For the Giant you would receive a dual planet configuration. Be careful to remove the external position checking magnets after verifying that the internal ones are at 180° exactly.

Step two:

One difference to note is the eTracker boost hub. It requires a replacement end cap which relocates the wrench flats out of the way of the PLANET3 ring gear. You will receive this with your PLANET3 if you have selected an eTracker hub in the product configuration. As far as the replacement goes, you’ll need two 17 mm cone wrenches to remove the original and replace with the one you would receive (if the braking side is the one to come loose first). If the drive side becomes loose instead, then it’s a bit of a issue: cassette tool and chain whip are needed, remove the cassette, remove the drive side end cap, get a 12 mm allen key (rather huge), stick it in the axle, then remove the braking side end cap, use Loctite to re-fit and tighten the drive side while holding the other side with the aforementioned 12 mm allen, then finally fit the braking side replacement end cap that you would receive – also Loctite on the threads. Torque to use is like this: tighten until snug, then another 30°.

Step three:

We would recommend to pay attention to the installation depth of the ring gear too.

During your installation we would highly recommend for you to perform the empty device test as outlined at the end of the previous video. If there is no scraping sounds of plastic on plastic – you’re good to go, your frame is not at risk, you have correctly gauged the installation depth of the ring gear and PLANET3 should never wear out.

Be aware to be careful in the last step too when you put the wheel back into the bike. You could hit the PLANET3 ring gear against the frame or sensor when you’re aiming the disc into the calipers. So we recommend to do everything really gently during all installation process.
