What is the timing of Highlander six cylinders?

Align the timing chain of Highlander 2.7 in Pacific Auto Network, remove the valve cover and shake the crankshaft to make the concave parts of the two camshafts face each other; Insert the special tool into the rear ends of the camshafts to fix the two camshafts. Then remove the bolts on the special bolt hole for fixing the crankshaft and the lower right of the throttle valve on the steel body to fix the angle of the crankshaft. At this time, the time is right.

With the continuous progress of automobile manufacturing technology and industrial development, the synchronous belts of some engines have been replaced by engine chains. Compared with traditional belt drive, chain drive is reliable, durable and space-saving. The whole system consists of gears, chains and tensioners, in which the hydraulic tensioner can automatically adjust the tension, making the chain tension consistent and maintenance-free for life, making it have the same life as the engine, which is not only safe, but also improves its reliability to a certain extent.

For precision instruments such as engines, each mechanical part has strict technical and technological indicators, which makes the whole assembly process require high operating quality. As an indispensable part of automobile core, timing chain is also difficult to assemble. On some engines, there are several obvious signs to ensure accuracy and reduce some installation difficulties.
