Bafang BBSHD BBS02 M33 Locknut
This is the Bafang BBSHD BBS02 M33 Locknut and cover. If you have the Bafang BBSHD 1000 watt or the Bafang BBS02 750 watt electric bike motor kit then you have these two items. These replacement parts come in handy if you strip the fixing nut or the retaining cover gets scratched. While I have yet to see anyone break the M33 nut I have seen the retaining cap overtightened and cracked. The torque specification of the M33 locking nut 30-40Nm and the torque specification for the M33 cap is 20-30Nm. If you do not have a torque wrench you can tighen it as much as it seems reasonable. If you are unsure it is best to ask your local bike mechanic and I am sure he or she would be glad to advise you.
When installing the Bafang BBSHD BBS02 M33 Locknut and lock ring cover, tighten using the Bafang spanner. Before installing the locknut apply Loctite Blue to the threads. If you think you do not need the Bafang spanner to install this locking nut then read the post on The Humble Bafang Spanner.
We sell a lot of the Bafang Spanner, motor installation wrench, because they are necessary for the installation of your Bafang mid drive. They are inexpensive and will last for many years
