In current vehicles, it consists of ‘releases’ evenly spaced (there are four in a four-cylinder engine), attached to the bottom of the pistons by connecting rods.



By engaging the clutch, rotational energy is transmitted through the gearbox and differential to the driveshafts.

Camshaft vs Crankshaft

A camshaft It is located in the upper part of the engine and the crankshaft is in charge of driving it through a chain or timing belt.

The camshaft has cam lobes throughout their size they work with the valvetrain (made up of the pushrod, valve lifter, valve spring, valve and tappet or rocker arm).

The crankshaft sensors must be repaired on time, although sometimes it is not possible to do so. a light of “check engine” on the dashboard, it reports that the vehicle needs immediate attention.

How does a supercharger work with a crankshaft?

Some drive units are equipped with a supercharger, which attaches a pulley to the end of the part, attached to the supercharger by a belt.

When the engine is running, this it rotates rapidly, driving the pulley, which moves the belt.

This allows the turbine in the supercharger to work, drawing in air and increasing the power the engine generates.

Main types of crankshaft repair

  • Polished
  • crankshaft pulley repair
  • channel cleaning
  • Replacing connecting rod bearings
  • Balancing of the crankshaft
