As you may already be aware, Bosch are just about to release a maintenance repair kit, which is designed to offer peace of mind to those owners that are buying an ebike that is out of the covered warranty period.
Given that the kit comes with the following items shown below, including outer case and gears, it offers exceptionally good value at a retail price of £95.00. Whilst primarily designed to be installed by a Bosch approved dealer, with correct tools, and due care and attention, I can't imagine it being outside the scope of a competent person to carry out the process at home. As well as looking easy to install, the kit also comes with a two year warranty. I wonder if anyone else advertising bearing replacement, could offer that kind of cover.
What seemingly never gets mentioned when people talk about replacing bearings within the Bosch drive unit, is that there is high probability of damaging the torque sensor when changing the left hand side (non drive side) bearing, which can lead to the ebike ghosting. I have replaced right hand (drive side) outer bearings my self for other people seeking help, and as far as I'm concerned this kit offers everything that you will need, without risk of causing damage to sensitive parts of the drive unit.
I was made aware of 'ghosting' a while back, by someone that had recently had a drive unit rebuilt by a non Bosch approved company, and wouldn't personally risk touching or dismantling anything beyond what is sold within this kit, and it is with good reason that no Bosch technician is permitted to so either. The torque sensor is tested and calibrated in what Bosch call an “end of line test” at the production facility. If you remove it, it’s not possible to check the calibration after refitting it....even if the paint is aligned across the nut and torque sensor shaft.
I shall update this thread over the next few weeks with defined photographs when I get the chance of being able to review the kit my self, but I certainly think that with what is being offered, it represent superb and hassle free value for money.
Markings as mentioned above.
