At the engine mod. 406 the oil pump is driven by an intermediate shaft, for engine mod. 402 the pump and ignition distributor are driven by the camshaft
On engines mod. 406, filter 2101-1012005 is used, installed at the bottom of the cylinder block on the right side.
In order to replace the filter, you need to unscrew the old filter and screw in the new one.
Put a waste oil container under the crankcase
Unscrew the plug and drain the oil from the crankcase
Compression (pressure at the end of the compression stroke) in the cylinders is the most important indicator for diagnosing the condition of the engine without disassembling it
You will need: a hex wrench “6”, heads “12”, “13”, “14”, a small chisel, a hammer
Drain the engine oil and coolant, remove the mudguard and accessory drive belt
The piston of the 1st cylinder is set to the position of the top dead center (TDC) of the compression stroke so that when carrying out work related to the removal of the timing chains, the installation of the gas distribution phases is not disturbed
Removal, repair and installation of camshafts ZMZ-405, ZMZ-406
