Installing injector
Installing injector: Install injector (1). Install hold-down device (2).
Important! Tighten bolt (3) hand-tight only so that holding-down element (2) is slack and if necessary injector (1) can still be turned.
Connect pressure line (2), tightening nuts (1) hand-tight only in the process.
Turn injector (1) if necessary in direction of arrow until nuts on pressure line can be easily screwed on by hand.
Tighten nut (2) of pressure line hand-tight.
Then tighten down bolt for holding-down element (3).
Tightening torque, see 13 53 5AZ in 13 53 FUEL INJECTION NOZZLES AND PIPES .
Adhere to tightening sequence:
- First tighten down pressure line on injector.
Tighten down nut on injector with special tool (1) 13 0 161 and to torque (2). In so doing, grip hexagon head of injector with wrench (3).
