Taps must be clean and free of debris and
corrosion. Re-tap as necessary.
D Bushing - Inspect for wear, breakage, or
loosened bond with gland. Replace using
Loctite
®1 7471 Primer T and Loctite RC TM /640
or equivalent to adhere the bushing if any of

°
F
(204
°
C) is required to achieve full bond strength.
E Gland drive ring 1B - Inspect for wear or corrosion, especially at drive flat
surfaces on ID of drive ring.
3 Inspection and Reconditioning
3.1 There are certain critical areas of each part where special attention should be
paid to the condition. If any of the listed areas 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 critical area
listings for finish requirements). If any parts require machining to correct
damage, please contact your Flowserve representative for dimensional
requirements, or for any other questions regarding repair.
