Forkert montering af en olietætning kan føre til for tidlig fejl, olielækage og dyr nedetid. Uanset om du udskifter en krumtapakseltætning eller monterer en roterende akseltætning, montering af olietætning er kritisk.

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?

Du behøver ikke et helt værksted – men at bruge de rigtige værktøjer gør hele forskellen.

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

What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

• Hovedtætningslæbe vender altid mod væske- eller oliesiden (indad)
• Støvlæbe (hvis nogen) faces outward, toward contaminants

For skeleton seals like TG4 eller TC olietætning, inspect the lip curvature: the spring side always faces oil.

How to install an oil seal without leaks: full process

1. Fjern den gamle tætning
   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
   Se efter ridser eller riller - poler let efter behov.

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

5. Juster den nye tætning
   Center it squarely over the bore opening.

6. Tryk eller tryk jævnt ind
   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.

Never reuse old or deformed oil seals—even minor lip damage leads to leaks. Replacement is essential, especially when servicing timing covers or differentials.

Usually, ingen — but exceptions include:

Avoid getting sealant on the lip.
