Where is the timing mark on crankshaft?
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel, being the largest radius rotating at crankshaft speed and therefore the place where marks at one degree intervals will be farthest apart.
How do I adjust the timing on my camshaft?
Begin with the dial indicator in place on the intake lobe for the number-one cylinder and rotate the crankshaft clockwise until you reach the valve’s maximum lift. Zero out your dial indicator. Now rotate the crank counterclockwise until you have dropped at least 0.100 in valve lift.
Why do you need to lock down the timing belt?
Even though belts will not last as long as a chain, they are quieter and often easier to line up correctly with the cam and crank locked down. Anytime the belt is removed, the cam and crank need to be aligned to TDC No.1, which is where the marks on the crankshaft pulley line up with the pointer on the front cover.
Do you have to be dead on with timing belt alignment?
Because modern vehicles use so many electronics to control the engine with things such as crank and camshaft timing sensors, technicians need to be, as we say in the industry, “dead-on” with the timing belt alignment. The cam gear cannot be off by even a tooth, or the engine will set a DTC.
Where is the arrow on the timing belt?
Typically, there is a notch or a raised arrow on the bearing cap so it can be easily confirmed by eye when the two marks line up or, in the case of a stretched belt, do not line up.
Where is the timing mark on an Etude 1.6 engine?
Turn the crankshaft until the timing mark on the crankshaft sprocket aligns with the timing mark on the oil pump. On the 1.6 and 1.8L engines, align the E and the I marks on the camshaft sprockets are aligned with the marks on the backing plate (they should point down and towards each other at approximately a 45° angle).
