5.6.6. Adjustment of the maximum frequency of rotation without CD20 engine loading

Fig. 3.37. TNVD adjusting screws (CD20 engine): 1 — the screw of restriction of the maximum frequency of rotation; 2 — the screw of the shock-absorber of the drive of management of fuel supply; 3 — the screw of restriction of frequency of rotation of idling; 4 — the screw of the maximum supply of fuel

Warm up the engine up to the working temperature. At full supply of fuel measure the frequency of rotation of a bent shaft, without exceeding this mode more than on 5 pages. At discrepancy of the frequency of rotation demanded break a plastic cap of the screw 1 (see fig. 3.37), weaken a lock-nut and establish by this screw the necessary frequency of rotation of a bent shaft. Tighten a lock-nut and establish a new cap.
