started the narration here post 599 https://www.thetriumphforum.com/threads/whats-the-last-thing-you-bought.29958/page-30#post-624069 update got the 36mm socket removed the cover of the front sprocket being careful with the quick shifter sensor and it's cable tried the nut with a large breaker bar ... hmm I'm turning the engine got my daughter to step on the rear brake still no joy and it got dark , will continue tomorrow search in youtube and found this video, no use of the rear brake and a bit of tapping on the tool making things a lot easier:
It seems a common problem, often it can be removed with a windy/rattle gun, (not sure how well that translates across the pond, but it's an air or electric powered impact driver). Any handy?
an impact gun, no I do not have one nor any of my friends my wife has objected the installation of a large air compressor where she parks her car so no, I have not purchased one I know there are electric ones The nut has traces of locktite... on my previous service I told the dealer the nut had come loose I think they added some, I let them sort it
New chain, sprockets and chain guides It rides very smoothly Only $50 for the labor and about 90 mins to ride back and forth to the dealer in busy city traffic
