How to adjust the clearance on a PD injector?
Now set your Angle gauge to 0 (ZERO) degrees, and with the relevant Hex Key/Hex bit attached turn the adjustment screw back (counter-clockwise) 180 degrees. Hold the screw in position, then re-tighten the locking nut with a spanner, and then torque to 30Nm with a Torque wrench.
How to adjust the angle of the injector?
Do not keep turning after firm resistance is felt, or damage to the injector can occur. Now set your Angle gauge to 0 (ZERO) degrees, and with the relevant Hex Key/Hex bit attached turn the adjustment screw back (counter-clockwise) 180 degrees.
Where can I get a new engine injector?
Washers and “o” ring part numbers above, you can get a genuine “kit” of seals etc on eBay for around £25. Carefully with a small bit of “used” scotchbrite give the injector ends a little clean. Lubricate the new injector “o” rings with some “O” ring grease, to aid fitting, if you don’t have that a small smear of new engine oil will suffice.
How often should you replace your fuel injectors?
If you need new ones, it is recommended to replace the whole set at the same time. We stock high-quality fuel injectors for every type of car. You have selected Quantity 1 x Brake Disc . Brake discs are recommended to always be changed in pairs. Therefore it is recommended that you select Quantity x 2 .
How do you know when to replace a fuel injector?
Another effective test is to measure the pressure loss in the fuel rail when each injector is fired and pulses for a set period of time. Use an electronic injector pulse tester for this. As each injector is energized, a fuel pressure gauge is observed to monitor the drop in fuel pressure.
What to do with a dirty fuel injector?
When the dirty fuel injector or clogged fuel injectors arrive for service those components that can be removed from the fuel injector such as O-rings, pintle caps and filter baskets are removed. The injector then is placed in an ultrasonic cleaning bath to clean the external part of the fuel injector.
What should the pressure be when opening a fuel injector?
The electrical connectors to the other injectors are removed, isolating the injector being tested. The difference between the maximum and minimum reading is the pressure drop. Ideally, each injector should drop the same amount when opened. A variation of 1.5 to 2 psi or more is cause for concern.
Why are fuel injectors more sensitive to fuel condition?
On older multiport systems that fire the injectors simultaneously, the computer compensates by increasing the “on” time of all the injectors, which can create an overly rich fuel condition in the other cylinders. Direct fuel injectors are more sensitive to restrictions because of the precise amount of fuel they inject into the combustion chamber.
