Adjustment procedures

Neither adjustments nor maintenance procedures can be considered independently, as each is directly related to the others. Adjustments are procedures designed to maintain maximum power, efficiency, economy and elasticity of the engine, while at the same time ensuring efficient and trouble-free operation. Engine adjustments are becoming more and more important every year to ensure the lowest possible emissions of harmful substances into the atmosphere.

If the routine maintenance schedule has been followed scrupulously since the vehicle was purchased, and fluid levels and wear parts have been checked frequently, as suggested in this manual, the engine will be in relatively good operating condition and the need for additional work will be minimal.

However, it is more likely that the engine will perform poorly at times due to a lack of regular maintenance. This probability increases even more if the car was purchased used and did not previously have regular and frequent technical inspections.

In such cases, engine adjustments must be performed in addition to regular maintenance.

It is recommended to follow a certain sequence of adjustment procedures. The adjustment consists of three stages:

Analysis is the process of determining whether the decrease in performance is due to normal wear and tear or whether parts need to be replaced or repaired.
Replacement of parts - removal of worn and broken parts.
Service/adjustment - during this process, the parts must be cleaned, adjusted, secured and the required adjustment parameters must be achieved.

The length of time for an engine tune-up is usually determined by the time that has passed since the last service, but driving style and the overall condition of the engine must be taken into account. Non-standard maintenance should also be performed at regular intervals depending on operating conditions.

Troubleshooting is a logical sequence of procedures designed to determine the true cause of a malfunction. Maintenance usually involves two stages: diagnostics and repair. Very often the cause of a malfunction is wear or damage to parts. In this case, there are no special problems in troubleshooting. The first step is to identify the problem and its cause. Once the cause has been identified, refer to the appropriate section in this manual for repair, replacement or adjustment. Before performing any operation, please read the relevant section of the manual.

The first step in most diagnostic and adjustment operations is checking the cylinder compression, which provides important information about the condition of the engine and its systems.

If, for example, a compression test indicates severe wear on internal engine components, then traditionally performed adjustments will not improve the engine's condition, but will simply be a waste of time and money. Because of its importance, the test must be performed by a professional with the appropriate equipment, knowledge, and ability to properly apply both.
