Hi Folks,
Thought I’d close the loop on this one, with the news that I gave up. No matter what I tried I couldn’t get the bloody things out, so I took it to the Authorised Repairer here in Brisbane..

..who also couldn’t get the fkn things out. Instead he’s provided me an entire replacement head assembly, so if anyone needs a replacement motor or anything hit me up - I’ve got some random crap to sell
