3.1 There are certain critical areas of each part where special attention should
be paid to the condition. If any of the areas listed in 3.2, 3.3 or 3.4 show signs
of wear, corrosion, or other defects that cannot be removed without affecting
the dimensional size of the surfaces by more than 0.001 to 0.002", then the
respective part should be replaced. If grit blasting is performed, it may be
necessary to polish the O-ring surfaces to achieve the required surface finish
(see 3.2A and 3.3A for the required surface finish). If any parts require mach-
ining to correct damage, please contact your Flowserve representative for
dimensional requirements, or for any other questions regarding repair.
A Threaded holes - Inspect for thread damage and
re-tap as necessary.
B ID bore roundness - No greater than 0.002" TIR
C Set screws - Replace cup point and dog point set
screws with those included with the repair kit. Make
sure the same threaded holes are used with the same
type set screws.
