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?

Vous n’avez pas besoin d’un atelier complet, mais utiliser les bons outils fait toute la différence.

Outil Fonction
Outil d'installation/de presse de joint d'huile Applique une pression uniforme sans endommager le joint
Maillet en caoutchouc Appuyez doucement si l'outil d'installation n'est pas disponible
Solvant de nettoyage Prépare la surface de l'arbre pour l'étanchéité
Lubrifiant (par exemple huile moteur) Aide le joint à glisser en place
Tournevis à tête plate / médiator Enlève soigneusement l'ancien joint
Micromètre / Pied à coulisse Vérifie la correspondance entre la taille de l'arbre et celle de l'alésage

Some kits include their own installer. You can also choose a universal press tool when ordering replacement seals like our Joint d'huile TG4.


What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

  • Lèvre d'étanchéité principale fait toujours face au côté fluide ou huile (vers l'intérieur)
  • Lèvre anti-poussière (le cas échéant) faces outward, toward contaminants

For skeleton seals like TG4 ou Joint d'huile TC, inspect the lip curvature: the spring side always faces oil.
