Maintenance
End Suction Configuration
First, complete the steps in "End and radial suction configuration common assembly
procedures" before completing the steps below.
1. Clean the fitting surfaces between the bearing sleeve (197A) and suction casing (100S).
2. Coat the casing bearing bore and the outside of the stationary bearing (197A) with Loctite
635.
3. Insert bearing sleeve (197A) and tolerance ring (505D) into the casing sleeve retainer. Use
care. This can be facilitated by placing the bearing sleeve in a freezer for approximately
one hour and heating the suction casing with hot water. When the casing has been heated,
insert the bearing sleeve into the casing bore. The greater the temperature difference
between the bore and the sleeve, the easier it will be to insert the bearing sleeve. An
assembly fixture that can aid in this portion of the assembly can be made or can be
purchased from Goulds.
4. Replace tolerance rings (505D) and sleeve bearing (117) on the end of the shaft.
5. Replace cap screw (469Y) and retaining plate (467) on end of shaft.
6. Replace suction casing (100S) and align with shaft.
7. Install tie rods through the tie rod holes in the suction casing and secure them to the
discharge casing by threading them into the casing using the flats on the tie rods to screw
them into the discharge casing or by using the tie rod nuts (357F) and tie rod washers
(437A).
8. Install tie rod nuts (357F) and tie rod washers (437A) on tie rods and tighten to correct
torque values.
See Appendix A for correct torque values and Appendix D for correct torqueing sequence.
9. Slide seal and gland into position over seal chamber studs (356Y) and install and tighten
seal chamber nuts (357K).
10. Remove setting clips and retain for future use.
11. Spin shaft by hand to check for any binding or other potential problems.
12. Install flush piping to seal gland.
