Removal

Fig. 2.252. Shtekernye connections for a ljambda-probe and heating of a ljambda-probe


Disunite electric штекерное connection 1 for a ljambda-probe and heating of a ljambda-probe (fig. 2.252).

Unscrew a ljambda-probe 2 by means of the tool from the complete set накидных keys for a ljambda-probe (fig. 2.253).

Installation
At use of the ljambda-probe which was in the use it is authorised to grease with heat-resistant paste only a carving. Hit of this paste on grooves of the case of a probe is not supposed.

THE NOTE
New ljambda-probes are greased by Ustanovkanoj paste, hit of this paste on grooves of the case of a probe is not supposed.

Ljambda-probe electroconducting should be necessarily fixed on the former installation sites to avoid contact of electroconducting with an exhaust pipe.
The inhaling moment: 55 Нм.
