Bearing Lubrication. Lubricate bearings before assembly with lubricant used in the related housing or
container to provide the first run-in until lubricant from the system can reach the bearings.
On direct contact, uncured silicone sealant irritates eyes. In case of contact, flush eyes with
water and seek medical attention. In case of skin contact, wipe off and flush with water.
Silicone Sealant. Silicone sealant is often used instead of a gasket to seal mating parts. The mating parts
must be clean, dry and free of oil or grease for proper adhesion. After silicone sealant has been applied, the mating
parts must be assembled immediately. 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 the mating parts.
Gaskets. Remove all traces of previous gasket and sealant before installing new gasket. Coat both sides of
gasket with sealant to provide added sealing.

Sealing Compounds. Use sealing compounds as required in each maintenance task.
Torquing. Tighten bolts, screws, washers, hoses and fittings as required in Appendix E or in each
Identification Tags. Put hoses, tubes, lines and electrical wiring in place by matching identification tags
