Part: Engine

Video tutorial

In order to disassemble the engine of the Triumph Bonneville T140, you need to loosen the screws that fix the engine block to its housing in the center of the frame, so that it is possible to disconnect all the appropriate pipes and connectors: once these components have been removed, it will be possible to proceed by loosening the screws that fix the cylinder and removing the piston from the corresponding connecting rod. This in turn must be removed in order to access the further components inside the engine compartment, replacing them with new spare parts.
