Oil seals are used to keep chemicals apart from lubricants such as oil/fat or water away to keep spinning shafts or bearings in proper working condition. Rotary shaft Seals are among the most commonly used seals for sealing lubricating oil, water or grease in different applications.
If the shaft or housing gets damaged, it must be repaired. If you replace only the oil seal, but the shaft or bore remain damaged, then there is a chance of premature failure or leakage. You can easily repair the shaft, for example using an SKF Speedi-Sleeve.
Prepare the shaft and prevent damage
Loosen the securing-clamp bolt at the base of the distributor, then carefully withdraw the distributor.
