Small fuel dispenser oil pump removal and reinstallation of note:

First, install the pump cover. Copper sleeve should be coated with a little grease in order to mounting oil seal and protection. When mounting the pump cover screws, should be strictly in accordance with the order of twice the diagonal tighten each screw tightening torque knob should be basically the same, so as not to pump cover and pump combination Mifengbuyan.
Next Before disassembling the pump cover shall sanding Woodruff keyway on the shaft, so as not to dismantle the pump cover scratches on Woodruff keyway burr seal, causing leakage.
Again before the pump is mounted on the pump separator pad should be carefully examined for damage, whether to put reversed. Pump installed, should ensure that the center plane of symmetry pump pulley and motor pulley central plane of symmetry in the same plane, the pulley does not allow a clear swing and axial runout phenomenon.
At the same time the rotor assembly into the pump chamber, the application of hand (or stuck with a rigid shaft keyway hand) rotating rotor blades look carefully at whether the retractable blade slots, while viewing the rotor blade is higher. If higher rotor blades, the blades shall be polished. So that the rotor contour or slightly below the rotor.
And before servicing must be reliably cut off the power. Remove the belt from the pulley, so as to avoid accidental injury. Ready tipping the oil container to avoid oil pump and oil separator drain spilled everywhere. Finally, before you re-install the pump, use kerosene to clean all parts, do not allow any sticky dirt to avoid scratching the pump, resulting in a new fault.
Caution Disassembly and reassembly of the small auto fuel dispenser oil pump requires very close attention. The requirements of the pump seal, no leakage, the moving parts can move flexibly cable wiring, noise and vibration at work. So the various demands of the tanker is also very strict. For these considerations need more attention. After reading notes on a small heavy duty fuel dispenser oil pump is also to look at some of the latest developments on the submersible pump.
