FIELD MAINTENANCE
GENERAL ASSEMBLY INSTRUCTIONS
INITIAL SETUP:
Not Applicable
PREPARATION
Remove protective grease coatings from new parts before installation.
PREFORMED PACKING INSTALLATION
Lubricate all preformed packings with a thin coat of light lubricating oil (WP
0193, Table 1, Item 43) before installing.
To install a preformed packing, first clean the groove, then stretch packing and place into position. Place component
on flat surface and uniformly press packing into position. Ensure preformed packings are not nicked or torn during
assembly.
END OF TASK
PIPE JOINTS AND FITTINGS
CAUTION
Use sealing compound sparingly and only on male threads. Do not apply compound on first
two threads to avoid contamination of system from compound. Do not apply compound to
hose connections or fittings with preformed packing. Damage to equipment may result.
Use sealing compound, sealant, or adhesive as indicated in each maintenance task. Refer to General Installation
Instructions (WP
0130).
END OF TASK
OIL SEALS
Coat oil seals evenly with oil or grease before installing. Install oil seals with seal lip facing toward lubricant, applying
an even force to outer edge of seal. If oil seals are to be installed over keyed or splined shafts, use a guide to prevent
sharp edge of keyway or splines from cutting the leather or neoprene seal. Construct guides of very thin gauge sheet
metal and shape to the required diameter. Make certain guide edges are not sharp and are bent slightly inward, so
they do not cut the seal.
END OF TASK
BEARINGS AND SHAFTS
When mounting bearings on shafts, always apply force to the inner races. When mounting bearings into housing,
always apply the force to the outer race.
