Replacing the front crankshaft oil seal
If you find traces of oil leakage through the crankshaft oil seals, first check to see if the crankcase ventilation system is clogged and if its hoses are pinched, and repair if necessary.
Between the flanges of the cylinder head and the catalytic collector there is a sealing gasket made of two thin molded metal strips connected by spot welding
To seal the joint between the flanges of the cylinder head and the intake manifold, as well as between the flanges of the throttle assembly and the intake manifold, sealing rings are installed in the grooves of the intake manifold pipes
Checking the technical condition of timing drive parts
Check the camshaft and crankshaft sprocket, tensioner pulley and roller for wear and damage
Checking and adjusting the valve clearance must be done on a cold engine (coolant temperature 20˚С ± 5°С), with the cylinder head installed on the block
If there is a loss of power, increased fuel consumption or increased oil consumption, it is necessary to check the compression in the engine cylinders
Checking and adjusting the valve clearance must be done on a cold engine (coolant temperature 20˚С), with the cylinder head mounted on the block
To prevent damage to the cylinder head, wait until the engine has cooled down before removing it
Checking the technical condition of timing parts
Sprockets, hydraulic tensioner, chain guide and tensioner arm
Checking the technical condition of the timing drive
Remove the top cover.
Check the timing belt (A) for damage, oil or coolant ingress
By default, we already have the cylinder head removed
Power units are designed for operation at ambient temperatures from minus 60ºС to plus 50ºС, relative humidity up to 98% at a temperature of 25ºС, air dust content up to 0.4 g / m 3, as well as for movement car in mountainous conditions at an altitude of up to 4500 m above sea level and overcoming passes up to 4650 m above sea level with a corresponding decrease in power and economic indicators.
Thermal gaps in the valve mechanism are used to ensure a hermetic fit of the valve on the seat, when the parts of the valve drive expand during engine operation
To adjust the fuel injection advance angle, two hatches are provided on the flywheel housing (see Fig. 1), and the angle values \u200b\u200bare marked on the flywheel in two places
The service life of the engine depends on the timely and thorough lubrication, as well as on the grade and quality of the oils and greases used
Install the driven coupling half (Fig. 1, 2) on the advance clutch (damper clutch) and fasten with bolts
When servicing each injector, check and adjust in the following order:
1. Adjust each nozzle to the injection start pressure:
Before starting the adjustment, flush the oil chamber of the pump and regulator with clean diesel fuel and fill with fresh engine oil up to the level of the drain hole
Before starting the adjustment, flush the oil chamber of the pump and regulator with clean diesel fuel and fill with fresh engine oil up to the level of the drain hole. For the duration of the test, plug the drain fitting
Draining sediment from the fuel coarse filter, washing the filter
Unscrew the drain plug 6 (Fig. 1), drain the sediment from the filter.
