LISTA pentru DIY - La ce cuplu sa strangem suruburile ?

[Roberto 410]

Am gasit lista asta cu cuplurile in Nm pentru diferite suruburi ale masinii. Eu zic ca e foarte utila pentru cei care bibilesc la masina singuri sau vor sa invete.

Pentru cei care nu stiu, toate suruburile din industria auto si nu numai trebuie stranse dupa niste specificatii si se foloseste o asa zisa Cheie Dinamometrica. Din pacate nici eu nu am, pentru componente mai putin importante le putem strange dupa mana, dar pentru unele foarte importante cum ar fi chiulasa ar trebuie o cheie dinamometrica cu care sa stragnem suruburile la cuplul specificat de producator.

Cuplul se masoara in Nm ( Newton\metru ) dar am mai vazut si in alte sisteme.

Cheile Dinamomentrice pot fi de mai multe feluri si sunt pe mai multe plaje de cuplu ( ex 30 - 100Nm, 200 - 300 ) in functie de scopul folosirii lor, etc. Nu ma pricep eu exact dar asta am citit si eu.

De asemenea, motivul general al ruperii sau craparii unor suruburi ( ex prezoane jante, sau dop baie de ulei cum a patit unul din colegii de forum este strangerea la refuz, fara simt\experienta si fara o cheie dinamometrica ).

Stie cineva unde gasesc o asemenea cheie, pentru amatori, nu vreau una profi ca e cateva sute de lei ci una amatoriceasca ?

Deci lista e in engleza, dar o sa o traduc candva.

Acest topic poate fi facut sticky eventual.

wow...Interesant de stiut.

[Midnight Caller 3,187]

    TOATE cuplurile sunt specificate in VADIS la proceduri de service. Nu e o regula sa strangi surubul M5 la 5Nm, pt. ca daca-l strangi in aluminiu iti trebuie un cuplu mai mic, daca il strangi in otzel e cu totul altceva. Conteaza mai mult IN CE infiletezi si pasul surubului decat CE SURUB infiletezi in el. Asta unu la mana

    Doi la mana, alege-ti de AICI : www.toptul.com o cheie dinamometrica dupa bunul plac, si in 2 zile ti-o aduc.

[Matrixxx 1,420]

Spune-mi si mie - unde sa caut pe site (cum se numeste) cheie dinamometrica  \

[Victor 18]

Si eu mi-am cam prins urechile in acel site. Mi-a atras atentia insa o trusa de scule. Fara pret.

Midnight, HELP!

[Midnight Caller 3,187]

Pai sa vedem... Pentru Matrixxx : Le gasesti la "Specialty Wrench"

[attach=1]

Si pentru trusa de scule... care din ele, ca "e mai multe"... Da-mi un cod !

[Roberto 410]

Torque Wrench se numeste in engleza.

Una potrivita pentru majoritatea surubaraielor la masina ar fi cea cu plaja intre 19 - 110 Nm care are acolo codul ANAF1211

Deci cat face una ?

[Midnight Caller 3,187]

Momentan singura livrabila este ANAF1621 - 270RON, TVA inclus, vine a doua zi.
