BROSE ALU Housing Belt Replacement Kit Gen. 1

Description

Original Brose Mag Belt Replacement Kit. This kit includes all spare parts required for the renewal or repair of the drivetrain. Use it to breathe new life into a faulty Brose Mag motor or to prepare your drive unit for future challenges. For optimal belt tension, the Brose tension pulley for Mag motors is also required. The replacement kit is only compatible with Brose motors that have a magnesium housing. If your motor has an aluminium housing, please use the Brose ALU Belt Replacement Kit instead.

So easy, great kit!

Opened up my 2019 Brose S motor for the first time. Surprised how clean it actually was, which made this belt replacement easy to manage. The kit is excellent and I used the new screws provided, even though the original 6 screws holding the motor together were fine.
The belt is substantially stronger than the original. I had accidentally purchased the Brose S Mag kit, but they come with the same belt, so I have a spare for to swap over in another 4-5 years!
