Lubrication system — description A pressure lubrication system is adopted to supply oil to the moving parts of the engine. The oil from the oil pan is sucked in by the oil pump through the oil receiver. After passing through the oil filter, the oil is...
Oil pressure check 1. Engine oil check. Check the oil for contamination, water, discoloration and thinning. If the quality of the oil is not satisfactory, change the oil. Use oils (according to API classification) classes СС, CD with...
Changing the oil and oil filter Warning: Prolonged and often repeated contact with mineral oil causes the natural oils to be removed from the skin, leading to dryness, irritation and dermatitis. In addition, the motor oils used contain potentially...
Oil pump Removing the oil pump Reminder: When repairing the oil pump, the oil pan and oil receiver must be removed and cleaned. 1. Drain engine coolant (see section " Cooling system "). 2. Drain engine oil ( see relevant...
