Action 54. Fuel pump injection
advance angle
Setup advance angle of fuel pump injec-
tion shall be within 17° to 19° before top
dead centre (TDC) (Д-245.5) and from
19° to 21° before TDC (Д-243).
Verifying and adjusting the fuel injection
advance angle is performed in a special-
ized dealer shop.
When installing the “Motorpal” (Czechia)
in-line fuel pump, the setup advance an-
gles of the injection shall be as follows:
• 15...17° before the TDC
(MTZ-900//920/920.2).
• 12...14° before the TDC
(MTZ-950/952/952.2).
• When installing the YAZDA fuel pump for
diesel engines Д-2 4 5.5 S2 (MTZ-
950.3/952.3) and Д-2 4 5.43 S2 (MTZ-
900.3/920.3), setup advance angle of injec -
tion shall be within 3.5°…4.5° before the
TDC.
• check the cleanness of the radiator
core. If necessary, wash the radiator
and blow the core with compressed
air (blowing direction from the engine
side).
ATTENTION! Radiator clogging, insuf-
ficient fan belt tension and impurities
inside the cooling system can lead to
diesel engine overheating and failure.
IMPORTANT! Adjustment of the fuel
equipment by the tractor operator (own-
er) is the ground for rendering the manu-
facturer’s warranties void.
Action 55. Adjusting the fuel pump on
the bench
Adjusting the fuel pump shall be per-
formed made by the dealer in a special-
ized shop using special equipment.
Action 56. Flushing the engine cooling
system
To flush the system, use a solution of 50-
60 g of soda ash per 1 l of water. To flush
the system, proceed as follows:
• Pour 2 l of kerosene into the radiator
and fill the system with the prepared
solution;
• Start the engine and operate the tractor
for 8-10 hours; then drain the solution
and flush the cooling system with clear
water;
