Never worked on a 500t but it looks the same as a cb 77. Not a big deal to replace the rollers. I would buy rollers, Part number 91101-377-000 3 each, spring, part number 28125-283-010 3 each and cap, part number, 28126-292-000 3 each. Clean up the outer clutch and put it back together. Make sure they are retracted when putting back on the crank.
