You didn't say what car. The pump on the TR3 has a handy little retaining
plate held in place with a screw. This plate secures the valves. Removing the
plate allows the valves to be removed and replaced.
But if you have a TR6 the valves are "staked" into place. This means the
valves are inserted into the bore in the pump base and then the material at the
edge of the bore is deformed to close up the opening just enough to retain the
valves. If look closely you should be able to see where the installer used a
punch to secure the valves. To change out these valves you need to file or
grind the deformed material enough to allow the valves to be extracted and
replaced after which you can "stake" them in with a hammer and a punch.
