Service Recommendations for Split Flange
IMPORTANT: (1) Be sure to clean and inspect
sealing surfaces. Scratches /
roughness cruse leaks and seal
wear. Unevenness causes seal
extrusion. If defects cannot be
polished out, replace the
component.
(2) Be sure to use only specified O-
rings. Inspect O-rings for any
damage. Take care not to file O-
ring contact surfaces. When
installing an O-ring into a groove,
use grease to hold it in place.
(3) Loosely assemble split flange
halves. Make sure that the split
is centrally located and
perpendicular to the port. Hand-
tighten the bolts to hold the
parts in place. Take care not to
pinch the O-ring.
(4) Tighten bolts alternately and
diagonally, as shown, to ensure
even tightening.
(5) Do not use air wrenches. Using
an air wrench often causes
tightening of one bolt fully
before tighten the others,
resulting in damage to O-rings
or uneven tightening of bolts.
Nut and Bolt Lockings
•
Lock Plate
IMPORTANT: Do not reuse lock plates. Do not try
to bend the same point twice.
•
Cotter Pin
IMPORTANT: Do not reuse cotter pins. Match the
holes in the bolt and nut while tight-
ening, not while loosening.
•
Lock Wire
IMPORTANT: Apply wire to bolts in the bolt-
tightening direction, not in the bolt-
loosening direction.
