the oil reservoir if necessary and without over filling . Use an ISO
VG 150 oil (recommended: Shell Vitrea 150, Mobil Rubrex 900, or
BP Energol CS 150) .

Remove the vane inspection screw and insert a 3/16" metal rod
with a tapered end into the inspection port (Figure 57) . Rest the
rod on the vane rotor and mark the rod . Rotate the drive shaft by
hand until the rod connects with the vane slot then mark the rod
again . Remove the rod and measure the distance between the
marks . If the distance is greater than 3/8", the vanes need to be
replaced (Figure 58) . Contact your authorized Balzer dealer for
