Removal
Remove the pump-injector. Very carefully pry and remove the used sealing rings from the pump-injector. Make sure that no burrs appear at the seating location of the sealing rings.
Installation
Instructions. Always use mandrels to install the sealing rings. Otherwise, there is a risk of damaging the sealing rings. Gradually switch to installing sealing rings without color markings. Observe the correct positioning of the sealing rings in relation to the grooves: the thickness of the ring decreases towards the injector. When installing, the sealing rings should be pushed on, not screwed on. Twisting the ring in its seat on the pump injector is not allowed.

Remove the heat-protective seal together with the retaining ring. Very carefully clean the seating areas of the sealing rings on the "SOS" injector. Put the mandrel -T10056/1. on the unit injector until it stops. Carefully insert the upper, thicker sealing ring into the mandrel and into the seat of the unit injector. Remove the mounting sleeve.

Place the "T10056/2" mandrel on the pump-injector until it stops. Carefully insert the middle, thinner sealing ring into the mandrel and into the pump-injector seat. Remove the mandrel.

Place the "T10056/3" mandrel onto the unit injector until it stops. Carefully push the lower sealing ring onto the mandrel and insert it into the unit injector seat. Remove the mandrel. Install a new heat-protective seal together with the retaining ring. Install the unit injector.
