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?

Você não precisa de uma oficina inteira, mas usar as ferramentas certas faz toda a diferença.

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

What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

• Lábio de vedação principal sempre voltado para o lado do fluido ou óleo (para dentro)
• Lábio de poeira (se houver) faces outward, toward contaminants

For skeleton seals like TG4 ou Selo de óleo TC, inspect the lip curvature: the spring side always faces oil.

How to install an oil seal without leaks: full process

1. Remova o selo antigo
   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
   Procure por arranhões ou ranhuras. Se necessário, faça um polimento leve.

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

5. Alinhe o novo selo
   Center it squarely over the bore opening.

6. Pressione ou bata uniformemente
   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.
