오일 씰을 잘못 설치하면 조기 고장, 오일 누출 및 비용이 많이 드는 가동 중단으로 이어질 수 있습니다. 크랭크 샤프트 씰을 교체하든 회전 샤프트 씰을 장착하든 적절한 오일 씰 설치 중요합니다.

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?

작업장 전체가 필요한 것은 아니지만, 적절한 도구를 사용하면 큰 차이가 납니다.

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

What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

• 메인 실링 립 항상 유체 또는 오일 쪽(안쪽)을 향함
• 더스트립(있는 경우) faces outward, toward contaminants

For skeleton seals like TG4 또는 TC 오일 씰, inspect the lip curvature: the spring side always faces oil.

How to install an oil seal without leaks: full process

1. 오래된 씰을 제거하세요
   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
   긁힌 자국이나 홈이 있는지 살펴보고, 필요하다면 가볍게 닦으십시오.

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

5. 새로운 씰을 정렬합니다
   Center it squarely over the bore opening.

6. 균등하게 누르거나 두드리세요
   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.
