Note:
1
This does not apply to VF10 and VF15 pumps as the rotor’s design incorporates the shoe
profile.
2
The VF80 does not have a split location dowel but instead has 2 bolts
Figure 9
• Check the shimming table, to ascertain the correct number of shims for each shoe to produce
the required flow at the required pressure, at the speed the pump is to operate
• Insert the required number of shims under each shoe and tighten the bolts to the correct
torque setting in “Parts List”, ensuring that the shoes and shims remain aligned correctly with
the rotor See Figure 09
Note: The shims must be inserted from the front edge of the rotor to enable shims to be removed
without taking the shoe off the rotor
• Clean up the output shaft and key with a piece of suitable emery cloth to ensure the rotor
slides on to the shaft with relative ease
• Loosen the Allen bolts in the taper lock bush fitted to the rotor. Remove one of the Allen
bolts and insert it in to the jacking position, then slowly rotate the screw clockwise to release
the bush slightly from the rotor, but do not remove the bush fully from the rotor
