GENERAL ASSEMBLY INSTRUCTIONS (CONT)
2. Packing Installation. Lubricate all packings with a thin coating of light mineral oil before installation. Slightly stretch
packing and place into position. Rotate component on flat surface or uniformly press the packing into position.
3. Pipe Joints. Use nonhardening pipe-joint compound or thread sealing tape when joining piping.
4.
Gaskets. To provide added sealing for gasket, coat both sides with sealant. Remove all traces of previous gasket
and sealant before installing new gasket.
5. Silicone Sealant.
WARNING
On direct contact, uncured silicone sealant irritates eyes. In case of contact, flush
eyes with water and seek medical attention. Avoid prolonged contact with skin.
Failure to do so could result in serious injury to personnel.
Silicone sealant is often used instead of a gasket to seal mating parts. Mating parts must be clean, dry, and free of oil
or grease for proper adhesion. After silicone sealant has been applied, mating parts must be assembled within 15
minutes. Silicone sealant starts to set up in 15 minutes and takes 24 hours to completely cure. Excess silicone
sealant should be wiped off after assembling mating parts.
6. Oil Seals. Install oil seals with seal lip facing toward lubricant, applying an even force to outer edge of seal. Coat oil
seals evenly with grease before installing. If oil seals will be installed over keyed or splined shafts, use a guide. This
will prevent sharp edge of keyway or splines from cutting the leather or neoprene seal. Construct guides of very thin-
gage sheet metal and shape to required diameter. However, make certain guide edges are not sharp. Bend them
slightly inward so they do not cut the seal.
7. Seal Rings. Coat seal rings with oil and carefully install into their bores. If seal rings must be installed over threaded
parts, temporarily wrap the threads with tape to protect the seal ring; then remove the tape.
8. Bearings and Shafts. During assembly of shafts and bearings in housings, first mount bearing on shaft, then install
the assembly by applying force to shaft. When mounting bearings on shafts, always apply force to the inner races of
the bearing.
9. Bearing Lubrication. Lubricate bearings before reassembly with the type of lubricant normally used in the related
housing or container. This will provide lubrication during the first run-in until lubricant from the system can reach the
bearings.
GENERAL INSTALLATION INSTRUCTIONS
1. Preparation. Before installing any parts, make sure they are clean and that both mounting surfaces are clean and free
of oil and grease (unless otherwise noted).
2. Installation. Make sure there is enough clearance to install part. Disassemble adjacent parts as needed to provide
working clearance.
