Mercedese CDI mootorite pihusti kinnituspoldi pingutus käib manuaali järgi nii: keerata momentvõtmega 7Nm ja siis 90 + 90 kraadi.
Mis on erinevus 90 + 90 ja 180 kraadi vahel?

Internetiavarus ütles "The torque setting is 7NM and TWO angles of 90. The second angle of 90 has to be done with care and "feel" as they do snap. ONLY use new bolts."

Teine avarus soovitas:"7nm then straight away turn the bolt a further 90 degrees, now go have a cup of tea / coffee and a smoke LOL..............Seriously, give them about 10 - 15 minutes to "stretch and settle"

Then carefully add the next 90 degrees.............
Now personally, and I've done a ton of these, I never get to the 2nd full 90 degrees, I do it carefully by an experienced "feel", and usually get around 60 to 70 degrees, and don't have repeat failiures..............."
