Replace roller rubber on HP 9825 tape drive

No way... It's fixed to the motor spindle, and carries a tacho disk (with clear and black lines) at the lower end. This is hidden inside the plastic chassis of the tape drive, between a light bulb and a phototransistor. I've not had my 9825 apart for some time, but I can remember that you take out the complete tape drive unit, and then remove the screws holding the PCB and mechanism to the mouting bracket. The motor assembly is held in place by screws from the 'bottom; (non-cartridge-side) of the drive, but I can't remember if you have to desolder any wires to get it to come free enough. Then you can remove the setscrew(s) that hold the roller to the motor and pull it off the spindle. Problem is that the setscrews burr the spindle, and often the roller doesn't want to shift... -tony
