Camshaft tools include sensor tools, timing chain retainers, alignment tools, retainers, holding tools, and actuator locks. Camshaft (or cam) holding and locking tools set the right timing on the timing belt once it is replaced. The proper timing of the engine valves is critical to ensure that the engine runs smoothly. Tensioner tools maintain needed force while unloading pressure from the timing chain.

Barring tools turn flywheels to the right position during service. They may be pneumatic or electrically driven to help mechanics perform maintenance on engines.

Crankshaft alignment tools are make- and model-specific tools that keep the crankshaft aligned during adjustments to the camshaft or timing chain.

Crankshaft ring tools help remove the front and rear seals from the crankshaft. They also remove wear rings from make- and model-specific engines.
