How do you set timing chain on camshaft?
Slide the crankshaft sprocket over the crank making sure the notch in the sprocket is even with the tooth. This will set the cam timing to zero degrees which is perfect for most street applications. Position the timing chain and cam gear onto the camshaft and dowel.
How are the gears connected to the camshaft?
These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly. These gears should each be marked to help you reference their relative position.
How are gears connected to the timing chain?
Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.
How is camshaft end play used in roller lifters?
A cam adapter and shims are installed behind the cam pulley to achieve proper alignment and camshaft end play (.008 to .012˝ of end play is recommended for flat tappet cams, but as little as .001˝ of end play can be used with roller cams). Reducing camshaft end play reduces side loading on roller lifters for longer life.
Do you need to replace the camshaft when replacing lifters?
Mostly old school..! The camshaft does not necessarily need to be replaced when replacing lifters, and often times is not. In the case of a 4 cylinder, especially, I would replace lifters without doing the camshaft since you can replace the lifters without removing the head.
Which is the correct timing gear for a camshaft?
Rotate the gear until the mark is at roughly 12 o’clock. Always defer to the manufacturer’s directions. With the camshaft in place, the upper timing gear should have its timing dot in the 6 o’clock position; the lower timing gear should show its zero-degree marking in the 12 o’clock position.
What do you remove from an engine to install a camshaft?
With the cover off the engine, remove the three upper timing-chain bolts, along with the lower timing gear if a new timing chain is to be installed.
When to change cam followers and hydraulic lifters?
You should always change the hydraulic lifters, or cam followers, at the same time as a cam. The two “wear in” together and if they are replaced separately the older ones will destroy the newer ones. They exchange metal between them, so that there is some cam metal incorporated into the surface of the lifters and vice versa.
