Handy and important tool, when the next timing belt or cam gear seal changes are due. The tool locks the two camshafts steady in position and allows stressless work on the gears or belts.
The two ends of the tools are made to fit the two camshaft nuts in the early and later engines, so it works for MX5/Miata/Eunos Roadster 1.6 and 1.8 Engines in the MK1, MK2 and MK2.5 cars.
Please note, the tool is made of hardened steel and tested to be capable of cracking loose the cam gear bolts. However this cannot be guaranteed (in case of seized, rusted connection) and is always recommended to losen them with the belt on and the car in gear.
