begin repairs pump its dismantling.Remove the four bolts that are tightened both halves pump .It is possible that over the lifetime of the bolts could corrode, and therefore will not be unscrewed easily enough.In extreme cases, particularly stubborn bolts cut off "grinder."
Clean the moving parts of the pump (piston) and other details of the internal structure of the layers and possible contamination.If the cause was the burnt coil, replace it with a new or rewind reel.Power coil pump flooded with water-resistant composition, reminiscent of an epoxy resin.It is quite easily knocked out of the pump housing .
Repel composition (compound) with core and rewind reel.In the absence of a suitable cross-section wire can produce a coil is designed not to 220, and a different voltage.It is important to maintain a power pump , so that it can develop the necessary traction.
With Tester Check the electrical cord.If you have a break or shorten the cord completely replace it with a new one.
Renovated coil assemble the pump.During assembly, it is important to correctly align the holes in the central water flow routing (it is made of rubber) and the top of the pump .When you build can easily be mistaken as part pump symmetrical.
to assemble pump , try it in action.If there is excessive vibration or changing noise pump tighten fixing bolts more thoroughly.
Tip 2: How to repair the fuel pump gasoline pumps
injection engines have two main functions - the supply of fuel from the tank to form a mixture, and place in the creation of the necessary injection pressure.One of the main causes of failure is a poor-quality fuel pump heavily contaminated fuel.
Attributes fuel pump failure - a problem at startup, or when the engine does not start at all or is put for too long.In the operation of possible disruptions in the motor, as well as unstable idle speed.The electric fuel pump is sometimes the pressure drops in the system.
First, check whether there is a fuel leak.To do this, connect the fuel pressure gauge and shut off the engine at the same time.If after 5 minutes the pressure indicator will be less than about 1.6 atmospheres, then one of the injectors or the fuel control is passed.To rectify faults, using gasoline pump repair kit, consistently replace the gaskets, filters, valves and diaphragm.
Sometimes the cause of a failure of the fuel pump is the fuel tank, which in its manufacture may remain small particles of metal falling from the fuel pump, and carve it out of action.An indication of this problem can be repeated several times during a working fuel pump failure operation of other vehicle systems.In this case, carefully inspect the tank, clean it, and replace if necessary.
If you find traces of oil leaks, check the fuel pump is mounted to the engine block, and then - a condition of sealing insulating gasket.
To remove the pump, first disconnect the supply and forcing gasoline pipe, unscrew the nuts and remove the spring washers, and then - the fuel pump itself.
In the case where the cause of the output fuel pump failure deformed steel diaphragm, they can strengthen the diaphragm from the usual time of the polyethylene film.This damaged the diaphragm should not be thrown away, but rather arranged between a diaphragm made of polyethylene.
sometimes on vehicles with high mileage petrol pump at maximum load "sewn up".The reason - the weakening of the diaphragm spring.The road conditions you need to stretch a little spring, and then put it in place.
