This stud is the correct fitment for the front of the crankcase to the cradle on the downtube of the front frame. Suitable for fitment to the 1963-1970 unit-construction Triumph 650 models.
Sourced from LF Harris in the UK, the stud is 7/16″ OD and 3-5/16″ long and threaded to 26 TPI. Zinc plated for corrosion and rust protection.
The stud secures the front of the engine to the downtube and is fastened with spring washers and nuts on each end.
The installation is straight forward and the nuts should be checked occasionally to ensure they are securely tightened.
