Necam EGI Distributor Cross Section
Be aware this drawing shows the Non-Volvo Stepper motor (113), recognized by it's top face not being flat. See how the piston is orientated. Thin-walled end into the dizzy body, thicker-wall closest to motor body.
Main faults:
1) Diaphragm (104) hardens with age, then leaks or if you're lucky only spring (105) requires re-tensioning.
2) DFCO (107) tip wears out, or complete DFCO fails.
3) Don't forget the spring washer (114) O-ring (115) or lose the ball-bearing (112)
4) O-rings (118) rarely fail despite all the kits to fix these.
