Put a straightedge over the paddles
and check that they are completely
straight and the distance between
s traigh t edge and end plates is as
shown (use the th ic k n ess gauge).
Note that the clearance between
end plates and paddles must be at
least 0.1 mm in both sides.
When the paddles are secured on
the rotor they will expand a little at
Make sure that the scraper has
been adjusted so as to only just

the ends. The clearance between
end plates and paddles should
therefore be checked after attach-
ment. It may prove necessary to
dismount the padd les and rub a
little off the ends to achieve the
neces sary tolerance.
If the clearance between end plates
and paddles is too small, the motor
may become overloaded.
5. Reassemble the rotary valve in
the opposite order.
Make sure that there is a clearance
of at least 0.1 mm between end
plates and rotor blades.
Check with a feeler gauge that no
obliquities have occur red during
mounting, resulting in a too small
toleran ce.
