On the cars of the latest production series, instead of a centrifugal oil filter, an oil filter with a paper filter element is installed, shown in fig. 1
To disassemble the filter and replace the filter element 9, do the following:
- - unscrew the filter from housing 1;
- - unscrew nut 15;
- - remove cover 3 with gaskets 2 and 4;
- - remove anti-drainage valve 5, washer 6 and spring 7;
- - pressing the clamp 14, move it inside the filter cap 8 by 3-4 mm and turn it so that the three teeth of the clamp 14 are set against the grooves of the cap;
- - remove clamp 14, filter element 9, bypass valve 10 and spring 11 from cap 8.
To unscrew the filter, the manufacturer recommends using a special key 245-1017071 or other available means.
After disassembling the filter, all its parts must be washed with diesel fuel.
The filter is assembled in the reverse order. Rubber gaskets 2 and 4 and anti-drainage valve 5 must be replaced, and gasket 2 should be lubricated with engine oil during assembly.
When installing the assembled cap 8 with the filter into the housing 1, after touching the gasket 2 of the housing, tighten the filter by another ¾ turn.
The filter is installed only by hand.
The safety valve 13 of the filter is adjusted to a pressure of 025-0.35 MPa and serves to maintain the required oil pressure in the main oil line.
Reducing (radiator) valve 12 - unregulated, designed to bypass oil into the main oil line when starting a diesel engine, bypassing the radiator.
The bypass valve 10 is adjusted to a pressure of 0.13 ... 0.17 MPa, it opens when the filter element is heavily clogged or when starting a cold diesel engine with a significant oil viscosity.
Adjustment during operation is not required.
It is possible to install a non-separable oil filter mod. FM 009-1012005, which is replaced when changing the engine oil.
It is allowed to install other non-separable filter cartridges instead of the above filter, with anti-drainage and bypass valves, having the following parameters: diameter - 95-105 mm; height 140-160 mm; landing thread - ¾ - 16 UNF.
