Camshafts & accessories

Supplier of products in and around the engine

  • The camshaft is driven by the crankshaft and controls the valve train of the engine. The camshaft helps to ensure that the intake and exhaust valves open and close at pre-determined times.
  • The duration of opening, valve stroke and movement of the valve on opening and closing are determined by the shape of the cam.
  • Camshafts are needed to replace those damaged or worn due to a long service life, neglected engine maintenance or unfavourable operating conditions.
  • To preserve the durability of newly installed camshafts, we recommended replacing the following parts at the sametime:
    • tappet
    • push rods
    • gasket set
    • camshaft bearings
    • rocker arm
    • tappet
  • Camshafts are fitted below the crankcase in approximately 60% of all truck and industrial engines. The intake and outlet cams control the intake and exhaust valves of the cylinder head via the push rods and rocker arms, in turn governing the exchange of gas in the engine.
  • The latest generation utility vehicle engines and passenger car engines have camshafts at the top. In-line engines have a maximum of two camshafts, V engines may be fitted with as many as four camshafts.
  • The camshafts are subject to bending and torsion forces. To withstand the high levels of strain over the long term, the camshafts have been designed with high strength properties. Camshafts may be cast or forged, depending on their intended purpose.

Camshaft accessories

  • Camshafts should always be replaced at the same time as their interacting sliding parts, to prevent damage due to wear of the latter.
  • The associated valve actuating elements (interacting sliding parts), such as tappets, rocker arms and hydraulic valve lifters, are available separately.
