1.2.20. Search and elimination of malfunctions

Probable cause

Elimination method
Knocks of a cranked shaft and bearing
    Wear of radical bearings The bearing is jammed The cranked shaft is bent Excessive axial gap of a cranked shaft
    Replace Replace Replace Replace the persistent bearing

Piston and rod knocks

    Wear of bearings The bearing is jammed The piston finger is worn-out Wear of the piston in the cylinder The piston ring is broken
    Replace Replace Replace the piston, a piston finger or a rod Restore cylinders Replace
Noisy operation of valves
    Jacks of gaps of valves are faulty Liquid engine oil The rod of the valve or the directing plug of the valve are worn-out or damaged
    Replace jacks of gaps of valves Replace engine oil Replace the valve or directing plugs of valves
Excessive wear of cylinders and pistons
    Low level of engine oil Engine oil is polluted Poor quality of engine oil In an inadequate way the piston and a rod are assembled The increased gap in the lock of a piston ring The air filter is polluted
    Check level of engine oil Check an oil condition Replace engine oil Repair or replace Replace Clear or replace the air filter
Knocks in shatunny or radical bearings of a cranked shaft
    Insufficient supply of oil Liquid engine oil The increased gap in bearings
    Check level of engine oil Replace engine oil Replace loose leaves of bearings
Damage of radical bearings of a cranked shaft
    Low pressure of oil Poor quality of engine oil Wear or ovality of necks of a cranked shaft Channels of supply of oil in cranked to a shaft are polluted Wear of bearings Bearings are incorrectly established Violation of concentricity of a cranked shaft or bearings
    Check level of engine oil Replace engine oil Check and repair a cranked shaft Clear channels Replace bearings and check greasing system Repair or replace bearings Replace
The noise published by a gear belt
    Wrong tension of a gear belt
    Adjust a tension of a gear belt
Low compression in engine cylinders
    Laying of a head of the block of cylinders is punched Piston rings are worn-out or damaged The piston or the cylinder is worn-out The valve saddle is worn-out or damaged
    Replace laying Replace rings Repair or replace the piston and / or the block of cylinders Repair or replace a saddle of the valve and / or the valve
Low pressure of oil
    Low level of engine oil The sensor of pressure of oil is faulty The oil filter is polluted Gear wheels of the oil pump or a cover are worn-out Liquid engine oil The safety valve is open Gaps in bearings are increased
    Check level of engine oil Replace the sensor of pressure of oil Replace the oil filter Replace the oil pump or a cover Replace engine oil Repair a safety valve Replace loose leaves of bearings
High pressure of oil
    The safety valve is closed
    Repair a safety valve
Engine vibration
    Engine support (forward and back) are not tightened The arm of fastening of a transmission is not tightened The arm of a podmotorny frame is not tightened The central support is not tightened The transmission support is damaged The support of a podmotorny frame is damaged The support shaft is damaged
    Tighten the demanded moment of a support of the engine Tighten the demanded moment an arm of fastening of a transmission Tighten the demanded moment an arm of a podmotorny frame Tighten the demanded moment the central support Replace a transmission support Replace a support of a podmotorny frame Replace a support shaft
Low level of cooling liquid
    Leakage of cooling liquid Damage of the core of a radiator Subjected to corrosion or the burst hoses (a radiator hose, a heater hose etc.) The valve of a cover of a radiator or spring installation is faulty The thermostat is faulty The water pump is faulty
    Replace Replace Replace Replace Replace Replace
Pollution of tubes of a radiator
    Extraneous inclusions in cooling liquid
    Replace cooling liquid
High temperature of cooling liquid
    The thermostat is faulty The radiator cover is faulty Channels or hoses of system of cooling are hammered The driving belt is not tense or torn The water pump is faulty The sensor of temperature of cooling liquid or its electroconducting is faulty The electric fan of a radiator or its electroconducting is faulty The temperature-sensitive element of the fan of a radiator or its electroconducting is faulty Insufficiently cooling liquid
    Replace the thermostat Replace a radiator cover Replace or clear the hammered elements of system of cooling Adjust a tension or replace a driving belt Replace the water pump Replace the sensor of temperature of cooling liquid Replace or repair the radiator fan Replace a temperature-sensitive element of the fan of a radiator Add cooling liquid
Low temperature of cooling liquid
    The thermostat is faulty The sensor of temperature of cooling liquid or its electroconducting is faulty
    Replace the thermostat Replace the sensor of temperature of cooling liquid
Leaks from cooling system
    Connections are weakened Hoses, pipes or oil radiator are damaged
    Tighten connections Replace or repair hoses, pipes or an oil radiator
The electric fan of a radiator does not work
    Elements are damaged
    Replace or repair the damaged elements
Leakages of the fulfilled gases
    Connections are weakened The pipe or the exhaust silencer is damaged
    Tighten connections Replace or repair a pipe or the exhaust silencer
Extraneous noise from system of production of the fulfilled gases
    The partition in the exhaust silencer is damaged The rubber suspension bracket is damaged The pipe or the exhaust silencer contact to a body The pipe or the exhaust silencer is damaged
    Replace the exhaust silencer Replace a rubber suspension bracket Adjust position of system of production of the fulfilled gases Replace or repair a pipe or the exhaust silencer
