WARNING
When you apply some silicone gasket materials,
a small amount of acid vapor is present.
To prevent serious personal injury, ensure
that the work area is well-ventilated. Read the
manufacturer’s instructions before using a silicone
gasket material, then carefully follow the
instructions. If a silicone gasket material gets
into your eyes, follow the manufacturer’s emergency
procedures. Have your eyes checked by
a physician as soon as possible.
6.On flange-type cylinders, apply silicone gasket
material onto the mounting surface of the
cylinder.
On threaded cylinders, apply a continuous
0.06-inch (1.5 mm) diameter bead of a flange
sealant, Meritor part number 2297-D-7076,
around the cylinder thread circumference.
7.Install the cylinder. On flange-type cylinders,
install and tighten the capscrews 7-12 lb-ft
(10-16 N.m).
NOTE:
The adjusting screw is set to the specified
distance after the input shaft assembly is
installed. El tornillo de ajuste debe ser montado
con la distancia especificada después
del eje del mecanismo de bloqueo estar instalado.
