3.1.4.2.1.4. System timing
THE GENERAL DATA

The cam-shaft is in a head of the block of cylinders and is put in action by a gear belt from a cranked shaft.

Phases timing


OZD
24 before ВМТ
ZZD
116 after НМТ
OZW
110 before НМТ
ZZW
18 after ВМТ
OZD and ZZD – accordingly opening and closing of the inlet valve
OZW and ZZW – accordingly opening and closing of the final valve

Phases timing are resulted at valve lifting on 1 mm and the fixed levers of all valves, except the lever of the valve which phases are measured.

Cam-shaft

Diameter of necks
45,7625 – 45,7375 mm
Axial backlash
0,02 – 0,15 mm
Thickness of a persistent plate
4,99 – 5,01 mm
Lifting of cams (inlet and final)
5,79 mm
Height of cams (inlet and final)
38,305 mm

The cam-shaft is made of pig-iron and located in five bearings in a head of the block of cylinders, fixed is longitudinal by means of a plate screwed by two bolts to a head of the block of cylinders and is put in action by a gear belt.

Gear belt

Mark
Motorcraft
Tension:
  – A new belt
350 – 450 Н
  – A belt were in the use (after 10 mines of work)
250 Н
The tension measured by means of adaptation Ford:
  – A new belt
10 – 11 units
  – A belt were in the use
4 – 6 units
Tension adjustment
By means of the mechanical roller tension device
