The oil pump is a component that seldom gives any problem as it is lubricated all the time and the only way it can go is due to lack of oil changes. If you have replaced the oil regularly, there is nothing you need to worry about.

I do not know which engine you have so I don't know if it is chain or belt driven. For any part that you work with, if there are any seals, get them replaced as seals ages overtime and deteriorates.
