Triumph OEM Service and Troubleshooting Manuals are available at, Rocuments. Note that this is a paid subscription service. A few years ago, when Triumph hosted the manuals on www.tritune.net it was possible to subscribe for just one month and download the manual pages. I do not know if that is still possible.
To access the manuals you will need to register with the site (see screen print), and then subscribe to the service.
