Inspection
1.
After thoroughly cleaning all the parts they
should be examined for signs of cracking, wear
or corrosion.
2.
Install the inner and outer rotors in the pump
body, bearing in mind that the chamfered edge
of the outer rotor enters the pump body first.
3.
The clearances are checked as shown in Figs.
L.7., L.8 and L.9.
NOTE: The relevant clearances for these
dimensional checks are given on Page B.8,
they are the clearances applicable to a new
pump and are intended to be used as a
guide. Should a lubricating oil pump be
worn to such an extent that it adversely
effects the working oil pressure, then a
replacement pump should be obtained. The
component parts of the pump itself are not
supplied individually,
