The retaining pin should be bent around using a small hammer or similar. Do not use a form of heat to bend the retaining pin as this will weaken the pin.

Should I replace all of my rollers at the same time?

In an ideal world yes; this ensures even wear across all new rollers. If a customer does not want to order a full set, the next best option would be a half set. In this case all the new rollers should be fitted on one side of the machine and the best of the worn rollers on the other side.
