A camshaft is a functional element of the vehicle's fuel system, responsible for the correct sequential opening and closing of the engine valves. Fuel consumption, developed power, stability of its operation, and other driving characteristics depend on the correctness of its functioning. The camshaft is a rod on which several so-called engine cams are located. These are irregularly shaped parts, rotating on the shaft axis. They correspond to the number of the intake valves in the cylinders and are located exactly opposite them. The set of cams is selected so that rotation guarantees stability and even combustion of fuel in the cylinders. And the work of hydraulic camshafts must be clearly synchronized with other engine mechanisms. On both sides of the engine cams , supported journals are put on the shaft, holding it in the bearings. One of the most important shaft assemblies are oil channels. The physical wear of parts, the power characteristics of the motor and the stability of its operation depend on their condition. To supply oil, a through hole was made in the camshaft axles with leads to the support bearings and cams.

Competent troubleshooting of the camshaft will save a lot of time and effort during repairs. A faulty camshaft most often gives out its condition with a characteristic knock, which occurs due to wear of bearings or cams, shaft deformation, mechanical failure of one of the elements. Such breakdowns occur both due to factory defects and as a result of natural wear and tear. Well, of course, in the event of a malfunction of other engine elements. Sometimes even the smallest part can affect the performance. of the camshaft.

Defect 1. Severe wear, scoring and scratches on the surfaces of the camshaft bearing journals.

The reasons:

• The engine is running with insufficient pressure in the lubrication system;
• The engine runs on low-quality oil;
• Severe overheating, leading to oil dilution;
• If fuel (gasoline or diesel) gets into the oil, it will dilute the oil;
• Running the engine with a clogged oil filter;
• High engine mileage, etc;

Defect 2. Severe wear and tear on the working surfaces of the camshaft cams.

The reasons:

• The engine is running with insufficient pressure in the lubrication system;
• Engine operation with insufficient oil level in the crankcase;
• The engine runs on low-quality oil;
• If fuel (gasoline or diesel) gets into the oil, it will dilute the oil, etc.

Defect 3. Cracked camshaft.

The reasons:

• Foreign objects entering the cylinder;
• Destruction of the timing belt or chain;
• Incorrectly set valve timing;

Defect 4. Development and scratches on the surface under the camshaft oil seals.

The reasons:

• Long engine running;
• Foreign matter entering the engine oil;
• Careless handling of the camshaft when replacing oil seals on the engine;
