As previously stated, Loctite™ or sealant was used during factory assembly for all fasten-
ers/hardware requiring the use of a thread lock or sealant compound, remnant compound AL-
WAYS causes false torque reading when installing old and/or new fasteners/hardware. Therefore
ALWAYS clean both sets of threads when installation instructions specify a torque requirement.
Use a cleanout tap (followed by a compressed air/water wash out) for female threads. Use a wire
brush (or die) for male threads (followed by a compressed air/water wash off). Use of a torque
lubricant is NOT required and is allowable ONLY for fasteners/hardware that do NOT require
thread lock or sealant compound. Specific torque requirements are provided within a procedure
when required. General torque values are provided in Table 22.

Circlip/Snap Ring Installation
All circlips (also called snap rings) should be installed with the sharp edge in the direction of
thrust support. If you examine the circlip closely you can determine which side has the sharp
edge by rubbing the edges with your finger. The edge of one side will feel sharp and the other
side will be rounded. The different edges are caused by the punch press stamping the circlips out
of a sheet of steel. Additionally the shape of the circlip is critical and for this reason they should
never be reused once removed. The pumps utilize three types of circlips: internal, external, and
general retaining as shown on Figure 13.

5.7.6 Thread Lock Or Sealant Compound
Loctite™ (or suitable equivalent/substitute thread locker) or sealant shall be used when directed.
Reference the procedures associated list of tools and/or consumables for the specific thread
locker or sealant required. Loctite™ (243, 680) or sealant (580) was used during factory assem-
bly for all fasteners/hardware requiring the use of a thread lock or sealant compound, remnant
compound ALWAYS causes false torque reading when installing old and/or new fasten-
ers/hardware. See paragraph 5.7.4, Replacement Fasteners, for thread lock or sealant com-
pound cleaning information.
The following Loctite™ compounds were used for thread lock or sealant during factory assembly.
• Thread Lock Compounds • Sealant

5.7.7 Cleaning And Inspection Guidelines
Wherever a procedure calls for cleaning and inspection, these guidelines should be followed.
A. Inspect all components for excessive or abnormal wear.
B. Wherever a requirement for new parts is indicated, obtain new components
