PULSE Installaon, Commissioning and Servicing Manual - Revision 19
8.1 Pre-Installation Check of Rotor Movement
A harsh knock in transit can affect clearance between the rotor, stator and rotor cover.
Before the belt is installed, test clearance by turning the pulley wheel by hand.
The wheel should move freely. If it is locked up, or excessive resistance is detected, carry
out the realignment procedure below.
8.2 Realignment Procedure
Use a 13mm spanner to loosen the four M8 rotor cover bolts, spin the rotor by hand
until it spins freely, then re-tighten the bolts. There is no particular sequence to tighten.
Tighten to 19-23 Nm.
8.3 Belt Tension
Tighten drive belt to 35lb.
8.4 Vacuum and Pressure Testing
IMPORTANT:
Vacuum / pressure gauges should be of the thread type G ¼ B and must be suitably rated
to record the vacuum or pressure of the pump. Vacuum is tested at the plug located at
the centre of the filter cover. Pressure is tested at the centre of the control valve cover.
