PRE-ASSEMBLY
Depending on the repairs, many steps in this section may not be applicable.
The assembly area should be clean and the environment such that foreign matter will not be introduced to the pump
during assembly. All parts must be absolutely clean and free from rust, contamination, lint, or any other foreign matter.
Critical surfaces must be free of dings or scratches. All "O" rings and seals must be clean and carefully examined for
cuts or other damage before installation.
During assembly, occasional reference will be made to the use of lubricating oil for proper assembly. It is important
that any oil used be compatible with the seals and fluid to be used in operation. Compatibility is also necessary for
grease which should be used on all "O" rings to ensure proper assembly without damage.
THREAD LOCKING AND SEALANT
Several screws require a thread locking compound for locking in position. When thread locking compound is required
use Loctite® #242 or equivalent. Where hydraulic sealant is specified, use Loctite® Hydraulic Sealant or equivalent.
Where gasket sealant is specified, use Loctite® Master Gasket or equivalent.
