ENGINE TESTING
Checking oil pressure
1.Remove union from rocker oil hole and fit a pressure gauge
graded from 0 to 8 kg/cm² (fig. 90).
2.Start engine and run up to 3000 RPM. Wait for the oil
temperature to reach 70 to 80°C.
3.With engine idling at 3000 RPM the pressure gauge needle
should be slightly over half way corresponding to a pressure of
3 to 4 kg/cm².
Said pressure will stabilize at 2 to 3 kg/cm² when engine runs
at full load and the oil temperature exceeds 70 to 80°C.
4.Reduce revs to minimum. The pressure should not fall to under
1 kg/cm² with the oil temperature exceeding 80°C.
Checking for oil leaks
1.Remove exhaust gas collection pipe from suction manifold and
close with a plug (fig. 91).
2.Start engine and run for a few minutes. The pressure which
forms inside the crankcase bring out any oil leaks.
3.Re-fit gas collection pipe to suction manifold.
5.Re-fit rocker covers and sealing gaskets.
Speed adjustment
1.With engine hot set minimum speed at 1000 RPM (fig. 88) and
maximum to idle (fig. 89) at:
2100 RPM for RD 278 engine
3150 RPM for RD 210 engines
3700 to 3750 RPM for RD 211 engines
2.Then stop the engine.
3.Remove injectors, clean nozzle holes carefully, check setting
and re-fit.
4.Adjust clearance between valves and rockers, while engine is
hot, to:
