(3)
Install the same number and
thickness of shims on the
rotor shafts (101 and 102)
that were removed at the
time of disassembly.
NOTE
When rebuilding a blower with new rotors or new gears, first install the gears on the rotor shafts
without the shims, then check the clearances between the rotors to determine the location and
thickness of shims to be used; refer to figure above.

Lubricate the serrations of
the rotor shafts (101 and
102) with clean engine oil.

same direction as the
serrations on the shaft.
