This is the two piece generator extractor for BDK race generators made from EN24T.
This extractor covers all of the BDK race generator range
When extracting rotors using the two-part extractor:
First carefully remove the aluminium threaded washer (with nut head), it is not necessary to remove the nut/threaded washer on newer versions as there is sufficient thread.
Engage the outer extractor fully.
Tighten the central extractor bolt until the rotor is released. Some models may require the bolt holding the rotor on, to be loosened so the extractor can push on that to release it.
