Cum se instalează o garnitură de ulei fără scurgeri: Ghid pas cu pas

Instalarea incorectă a etanșării de ulei poate duce la defecțiuni premature, scurgeri de ulei și timpi de nefuncționare costisitoare. Indiferent dacă înlocuiți o etanșare a arborelui cotit sau montați o etanșare a arborelui rotativ, corect montaj simeringul de ulei este critic.

In this guide, I’ll show you how to install oil seals the right way—without damaging the lips or misaligning the casing. This article covers tools, step-by-step procedures, lip direction, sealing surface prep, and tips for ensuring long-lasting performance.

What tools are needed for oil seal installation?

Nu aveți nevoie de un întreg atelier, dar folosirea instrumentelor potrivite face toată diferența.

Instrument Funcţie
Instalator de garnituri de ulei / Instrument de presare Aplică o presiune uniformă fără a deteriora garnitura
Cioc de cauciuc Apăsați ușor dacă instrumentul de instalare nu este disponibil
Solvent de curățare Pregătește suprafața arborelui pentru etanșare
Lubrifiant (de exemplu ulei de motor) Ajută sigiliul să alunece în poziție
Șurubelniță cu cap plat / Pick Îndepărtează cu grijă sigiliul vechi
Micrometru / Etrier Verifică potrivirea dimensiunilor arborelui și ale alezajului

Some kits include their own installer. You can also choose a universal press tool when ordering replacement seals like our Etanșare ulei TG4.


What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

  • Buză principală de etanșare este întotdeauna îndreptată spre partea de lichid sau ulei (înăuntru)
  • Buză de praf (dacă există) faces outward, toward contaminants

For skeleton seals like TG4 sau Garnitura de ulei TC, inspect the lip curvature: the spring side always faces oil.


How to install an oil seal without leaks: full process

  1. Scoateți sigiliul vechi
    Use a puller or flat screwdriver. Avoid damaging the housing.

  2. Clean bore and shaft
    Remove oil, dirt, and rust using solvent and lint-free wipes.

  3. Inspect shaft
    Căutați zgârieturi sau caneluri - lustruiți ușor dacă este necesar.

  4. Lubricate lips
    Apply a thin coat of oil or grease—never install dry.

  5. Aliniați noul sigiliu
    Center it squarely over the bore opening.

  6. Apăsați sau atingeți uniform
    Use a seal installer or socket. Do not hammer the center.

  7. Confirm flush seating
    Outer edge should be level or slightly recessed—not protruding.

  8. Double-check orientation
    Ensure the spring side faces oil and dust lip faces out.
