One of our customers had a problem with his trigger wheel. It fell off!!! causing a dnf. So we set about a solution.

We sourced a new trigger wheel and steel bottom pulley and centralized the trigger wheel to the pulley on a mandrel in the lathe.

Then we TIG welded the trigger wheel to the pulley, machined the center out of the trigger wheel and machined the trigger wheel teeth to run concentric to the crankshaft. Zero run out achieved it now runs again.

Testing at Brands Hatch tomorrow.
