Swapping my original clutch pack for a full Sachs assembly sourced from IAP. The thrust bearing (machined piece on the back end where the fork engages) has significant slop as compared to the 90,000 mile one I just removed. However, if I push it forward firmly against the pressure plate, simulating depressing the clutch pedal, the slop disappears and it spins smoothly with little to no play. Everything is obviously new manufacture. Need I be concerned?
