Twin Cam Crankshafts?

I have recently learned on a UK Harley website that the pressed together cranks in twin cams require some special expertise that is only available in the USA! The suggestion is that if a UK Harley owner needs a crank rebuilt it has to be sent 'back home'. My Dyna service handbook tells us all to send a crank in need of attention back to the factory for service or replacement.

As a keen 'Velo fellow' I have owned Velocette bikes, which have pressed cranks, so these things ain't a mystery to me. I don't claim to have the skills to strip and rebuild a Velo crank myself, but I have watched it being done. It ain't difficult! It isn't rocket science, so what is it about these crankshafts that requires service behind closed doors?

I am interested to hear from our engine experts in HDF, to understand just what it is about a twin cam crankshaft that limits who is able to strip and rebuild them to the factory.

Graham,
I would imangine that the folks that attend to to Velocette cranks, can do the same with a Harley pressed-togather unit as well.
No need to send 'em here. I agree.

No rocket science, search You Tube for TheKingOfCube's Channel and watch the video on flywheel rebuilding.

As the others have said, crank repair can be accomplished other than at HD, but that being said, I don't know of anyone in the UK that does this, but you might want to contact Boz at powerglides.com in the UK, if anyone would know, he would.
