Колега може ли да ми кажеш тази глава на кои ремонт е?

[M10 Профил]

When skimming the head, look for dimples in two corners of the head face. These are your depth gauges, and the head can be skimmed until these dimples disappear.

Маркерите мисля че бяха към 1мм на нечелосвана глава. Мериш дълбочината и си правиш изводи колко е челосвана.

Тези болтове за глава добри ли са?

П.П. Колега много благодаря за помощта

[~Мишо~ Профил]

Добри са. Ползвал съм Goetze на друг мотор и съм доволен.

Няма как да свалиш помпата без картера преди това. Откачи маторя от тампоните, отвии тампоните на кутията и надигай, докато главата опре в купето. По спомен, на блока под мястото на компресора на климатика, имаше подходящо място за надигане. За лагерите по-добре викни човек в час с ремонта на матори. По цвета им можеш да се ориентираш, но трябва да се замери износване на вала за да не изтропа с новите

Колега благодаря ти много за помощта

Имам 2 последни въпроса:
Измерихме вала с микрометър и няма абсолютно никакво износване. Биелните лагери ще ги сменим. Въпросът ми е основните дали са за смяна като не са износени но са си сменили цветът и имат едни микро дупчици по тях?

Втория ми въпрос е последствие на първия. Ако сменям основните лагери мога ли да освободя вала от всички лагери и да избутам черупките за да ги сменя без да махам кутията и двигателя от купето или мога ли само да сменя долните черупки на лагерите на място?

И основните са за смяна, става да се сменят на място, като отвиеш и 5-те пети има достатъчно разстояние да избуташ старите черупки и да вкараш новите.Не съм го правил на 6 цилиндров мотор, но би трябвало да няма проблеми.Успех

кутията от m10, 5 скоростна, влиза ли на m40?

[M10 Профил]

Не става.

[tontoni Профил]

Здравейте, не мога да се оправя с аутодата и ви моля пак за помощ. На колко нютона се стягат основните, биелните лагери и главата? Двигателя е с блок м20б27 ета.

[~Мишо~ Профил]

Тампони за задните амортисьори от Е36 на Е30 пасват ли? Гледам са с различни номера, но ми изглеждат еднакви.

[KPETEH Профил]

До колкото знам пасват, но никога не съм слагал.

[Kroki]

По спомен се слагаха от Е46 кабрио, че били най-здрави.

[tontoni Профил]

Колеги имат ли разлика тампоните на дифа (за малко и голямо прасе)?

[Kroki]

Не.
