When assembling needle rollers in outer race preparatory to final assembly, apply a small amount of grease to hold rollers in place. Assemble specified number of rollers and observe that uhe last roller goes all the way into place freely and without requiring any effort to force it. If it doesn't go into place freely, leave it out. This is sometimes necessary when fitting oversize rollers, because they not only take up radial clearance, but also take up circumferential clearance. Rollers must not be crowded.
