An oil seal is a type of mechanical seal used to prevent the leakage of oil from machinery components. The dimensions of an oil seal are usually specified in terms of its inner diameter, outer diameter, and thickness. For example, a 38x52x7 oil seal has an inner diameter of 38mm, an outer diameter of 52mm, and a thickness of 7mm.

Put a wooden block or a piece of large tube against the seal and gently tap it squarely into the housing until it is fully home. Refit the timing cover, if removed.
