Automotive timing tools are mostly available as sets or kits. The set then typically contains a tool for each movable part of the timing system. The contents of timing tools kits are different across manufactures and car types. Just to give you an idea of what's included, here is a list of the main tools in a typical kit.
● Camshaft locking tool
● Camshaft alignment tool
● Crankshaft locking tool
● Tensioner locking tool
● Flywheel locking tool
● Injection pump pulley tool
Let's see where and how each tool is used.
Camshaft Locking Tool- this timing tool secures the position of the camshaft sprockets. Its function is to ensure camshafts do not lose their setting relative to the crankshaft. You insert it into the sprockets when you have to remove the timing belt, which can be during the belt replacement or when changing a part behind the belt.
Camshaft Alignment Tool- this is the pin or plate that you insert in a slot located at the ends of the camshaft. As its name suggests, the tool comes in useful when looking to correct or establish proper engine timing, especially when servicing a belt or doing major valve train repairs.
Crankshaft Locking Tool- just like the camshaft tool, the crankshaft locking tool locks the crankshaft during engine and cam belt repairs. It’s one of the main timing belt locking tools and exists in different designs. You normally insert it after rotating the engine to the Top Dead Center for cylinder 1.
Tensioner Locking Tool- this timing belt tensioner tool is specifically used to hold the tensioner in place. It’s usually fitted once you release the tensioner to remove the belt. In order to ensure the timing remains set, you should not remove this tool until you have re-installed or replaced the belt.
Flywheel Locking Tool- the tool simply locks the flywheel. The flywheel is connected to the crankshaft timing system. As such, it should not turn while you service the timing belt or repair other engine parts. To insert the flywheel locking tool, rotate the crankshaft to its timed position.
Injection Pump Pulley Tool- this tool is normally designed as a hollow pin. Its function is to ensure the correct injection pump position in reference to the camshaft timing. The hollow design helps prevent fuel from pushing it out in the middle of a repair or timing job.
Other tools found in an engine timing tool kit and worth mentioning are tensioner wrench and balancer shaft tool. The tensioner wrench helps with securing the tensioner pulley when removing its bolt, while the balancer tool serves to set the position of the balance shaft.
The timing tools list above includes what you will usually find in a conventional kit. Some kits will have more tools, most of which often serve the same purpose. It depends on the type of kit and the type of engine that it’s meant for.
A universal timing tool kit, for example, will often have more than 10 different tools, some up to 16 or more. Usually, a higher number of tools means a wider range of cars that you can service using the kit. Many auto repair shops prefer universal timing tools. They are more versatile and cost effective.
