What causes a camshaft to fail?

A broken camshaft is usually caused by a connecting rod or other rotating part coming loose and striking it. Sometimes the cam will break after a short time of use because of a crack or fracture in the cam due to rough handling during shipping or improper handling prior to installation.

What do the numbers mean on a camshaft?

Is camshaft and crankshaft the same?

A camshaft uses egg-shaped “cams” to open and close engine valves (one cam per valve), while a crankshaft converts “cranks” (the up/down motion of the pistons) to rotational motion.

What’s the difference between camshaft and crankshaft position sensor?

The Camshaft sensor determines which cylinder is firing to establish injector synchronization and coil firing sequence in DIS systems. Crankshaft sensors set ignition timing, supply the RPM signal, and determine engine speed.

How do you diagnose a bad camshaft?

Symptoms of a bad or failing camshaft position sensorVehicle does not drive like it used to.

How do you check the timing on a camshaft?

Begin with the intake valve; slowly turn the crank clockwise until the lifter rises 0.050 inch. Stop turning the crank and read the degree wheel. This begins duration at 0.050 inch. If our cam card says the intake valve opens at 31 degrees BTDC, the degree wheel should show 31 degrees BTDC at this time.

How do you identify a camshaft?

Examine both ends of the camshaft. The end of the camshaft will be embossed with a two-digit engine prefix code, a grind number, and the series name of the camshaft. These three pieces of information will allow a consumer to identify the specifics of a given camshaft.
