Camshaft Locking Tool for MX5/Miata/Eunos Roadster

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.

Important note: Please be aware, there are cheap direct copies of this product, we developed from scratch. They are not hardened, but even if so, hardening below the correct rate causes the tool to bend (at this thickness) or hardening above – to crack.

    Works well- product is slightly different to how it is pictured above, but mounts in the same place as shown. I read wrong info (off another site) about the mounting point of the exact version I was sent. This threw me for about 40 mins!

    I had to tap it on with a rubber mallet in the end, as it’s a tight fit, but that’s what’s needed to hold the cams accurately.

    The fit was poor as i had to tap the tool on and I believe it was machined incorrectly as the timing marks would not line up with the tool in place.
