Where it is necessary to replace a bearing or to disturb a seal, a new seal of the correct type and dimensions should be fitted. This is essential in the case of seals that protect the bearings in the hubs (front and rear). If these leak, braking efficiency is reduced. The three key dimensions as indicated in the search facility are:
The diameter of the housing into which the seal fits.
The diameter of the shaft on which the seal runs.
The width of the seal.
There are two main types of Oil Seal:-
Shafts should be checked for scoring. Score marks or burrs should be carefully removed.
