6.3 Replacing parts inside the pump housing
First detach the screw-in connections as described in chapter „Conversion to pump body pointing down“.
Loosen the 4 Torx screws M4x18 (Tx20) and lift the pump head along with mounting ring and foam cover off the console.
6.4 Replacing the bellow
To replace the bellow carefully unscrew it from the connecting rod counter clockwise. Be sure not to lose any installed shims.
Before reinstalling the bellow be sure it is not damaged.
Reinstall hand tight in reverse order.
6.5 Crank gear replacement
NOTICE
Restrictions for connecting rod-eccentric replacement
The individual replacement of the eccentric, connecting rod or bearings is not allowed.
Only the factory pre-assembled connecting rod-eccentric combination is suitable for re-
placement by the operator.
The crank gear consists of the connecting rod with ball bearing and eccentric.
After removing the bellow remove the set-screw inside the eccentric M3 using a size 1,5 setscrew wrench (or Tx6 for torx drive de-
pending on the screw type).
The crank gear may now be removed from the motor shaft.
