Instali olean sigelon malĝuste povas konduki al trofrua fiasko, naftofluado kaj multekosta malfunkcio. Ĉu vi anstataŭigas krankoŝaftan sigelon aŭ muntas rotacian ŝaftan sigelon, ĝuste instalaĵo de olefoko estas kritika.

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?

Vi ne bezonas tutan laborrenkontiĝon—sed uzi la ĝustajn ilojn faras la tutan diferencon.

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

What direction should the oil seal face to prevent leaks?

Installing backward is the most common mistake.

• Ĉefa sigela lipo ĉiam alfrontas la fluidan aŭ olean flankon (enen)
• Polva lipo (se ekzistas) faces outward, toward contaminants

For skeleton seals like TG4 aŭ TC oleo sigelo, inspect the lip curvature: the spring side always faces oil.

How to install an oil seal without leaks: full process

1. Forigu la malnovan sigelon
   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
   Serĉu grataĵojn aŭ fendojn - poluru malpeze se necese.

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

5. Vicigu la novan sigelon
   Center it squarely over the bore opening.

   Use a seal installer or socket. Do not hammer the center.
