2.7.6.2. Check

Fig. 2.298. Gap measurement between internal and external rotors


Measure a gap between an internal rotor and an external rotor, using щуп (fig. 2.298).
If the size of a gap exceeds the maximum value, replace an internal rotor, an external rotor or both rotors.
Standard gap between heads of teeths: 0,18 mm.
The maximum gap between heads of teeths: 0,20 mm.

Fig. 2.299. Gap measurement by an external rotor and case


Measure a gap between an external rotor and the case, using щуп (fig. 2.299).
If the size of a gap exceeds the maximum value, replace an external rotor, the case of the oil pump or an external rotor with the case.
Standard gap: 0,175 mm.
Maximum gap: 0,20 mm.

Fig. 2.300. Measurement of a lateral gap of the case of the oil pump


Measure a lateral gap, using щуп (fig. 2.300).
If the size of a gap exceeds the maximum value, replace an internal rotor, the case of the oil pump or an internal rotor with the case.
Standard lateral gap: 0,03–0,07 mm.
Maximum lateral gap: 0,09 mm.

Fig. 2.301. Measurement of length of a spring of a plunzher


Measure length of a spring of a plunzher in a free condition, using штангельциркуль with noniusy (fig. 2.301).
If the length does not correspond to norm, replace a spring of a plunzher.
Length of a spring of a plunzher in a free condition: 45,94 mm.
