What is the function of a crankshaft sprocket?
As stated on other answers, the sprocket at the front of a crankshaft drives the timing chain or belt that turns the cam shaft. The gear at the back end of a crankshaft is the flywheel. Gear teeth on the edge of the flywheel engage the starter motor.
What gear is on the crankshaft?
The crankshaft gear drives two different intermediate gears: one intermediate gear transmits power to the camshaft gear, which in turn drives the valve mechanism via the camshaft. This ensures opening and closing of the valves.
How do you remove and refit a camshaft?
Remove the central bolt to take the sprocket from the camshaft. Slacken the cam-cover bolts evenly so that the valve-spring pressure is released slowly. When all the bolts have been removed, take off the cover with its integral bearing caps. Lift the camshaft from the cylinder head complete with the front oil seal .
How do you open a camshaft?
How many teeth on the camshaft sprockets?
The camshaft sprocket has 42 teeth, which means that for 90 degrees of rotation there are 10.5 teeth. This also means that if the other two holes are used to mount the sprocket the relative position of the sprocket to the cam is offset by 0.5 of a tooth (Figure 1).
Can the sprocket on the camshaft spin?
Some people report the camshaft sprocket spinning on the camshaft. This results in a loss of valve-piston timing and bent valves/damaged heads . The effect is very similar to a timing belt losing teeth and slipping.
What is a cam sprocket?
A cam sprocket is attached to a camshaft in a combustible engine to help maintain timing.
What are camshaft gears?
The camshaft gear is a car part which can be found inside the garage at home. It is attached to the camshaft with 1x10mm bolt. Alignment. The camshaft must be aligned properly before fitting the timing chain.
