Fit the track over the drive shaft and locating boss. Secure the track with the retaining screws. Ensure the drive shaft
has been completely degreased before locating the rotor onto the shaft via a split collet. Tighten the rotor bolt to a
torque of 13Nm to prevent the collet slipping during operation.

To remove the track, remove any tubing from the pumphead. Loosen the rotor securing bolt and give the rotor/bolt a
sharp tap to free the collet. Release the collet, and withdraw the rotor from the shaft. Loosen the two track securing
screws and pull the track clear. Use this method of removal and fitting in case cleaning is required.
