LUBRICATION INSTRUCTIONS
Refer to WP 0039 for detailed, illustrated instructions on proper lubrication. Some general practices
to remember:
a.
Use the correct lubricant.
b.
Keep lubricants clean.
c.
Clean all fittings prior to lubrication.
d.
Lubricate clean, disassembled, and new parts to prevent rust (WP 0038 00-2 "Preservation of
Parts").
e.
If a lubrication fitting will not accept grease, check for dirt or clogged fitting. This may require
removal, cleaning, and installation of the fitting. If the fitting is on a hydraulic cylinder and will
not accept grease, it may be due to pressure applied by the position of the cylinder.
Repositioning the cylinder may resolve the fitting not accepting grease.
APPLICATION OF ADHESIVES
1. General. Adhesives are recommended in some tasks to ensure and strengthen seals. The
following information describes their correct use and application.
2. Silicone Sealant. Silicone sealant (item 11, WP 0085) is used to seal parts against moisture.
Use the following instructions when applying:
a.
Anytime a seal is broken, the part must be thoroughly cleaned to remove any remaining
sealing compound and dirt.
b.
Thoroughly clean surface before applying sealant.
c.
When applying sealant, ensure that the area is completely covered. Press sealant into and
around parts as necessary.
d.
Silicone sealant will set in 15-30 minutes depending on temperature and humidity.
3. Loctite Adhesive. Loctite adhesive (item 12, WP 0085) provides a seal against leakage and a
resistance to loosening when used in the assembly of threaded, slip-fitted, or press-fitted parts.
Always use grade of Loctite adhesive specified and never use when other retaining means are
provided, such as lockwires, lockwashers, lockplates, and fasteners. DO NOT use Loctite adhesive
on brass fittings, plugs, or items that need frequent servicing, or when operating temperature
exceeds 300oF (149oC). Apply Loctite adhesive as follows:
a.
Before application, clean threads to remove oil, grease, and metal chips.
b.
Apply Loctite adhesive to second and third threads. DO NOT apply to first thread to ensure
system cleanliness.
c.
Loctite adhesive will dry in 6-24 hours at room temperature.
d.
Adjustments for elbows, gages, and valves can be made up to 24 hours after application without
affecting the seal.
