valve clean and functioning correctly.
This air flow has no effect
on crankcase pressure.
Locate the blower drive gears on the splined ends of the blower rotor
shafts.
With this blower, there is no requirement for lubrication
because the lobes of the rotors do not touch.
When positioned
properly, the rotors run with a slight clearance between the rotor
lobes and walls of the housing.
To change this clearance, move one
of the helical gears forward or backward on the shafts (relative to
the other gear), using shims between the gear and the rotor spacer.
