General Assembly Instructions
viii
• Lipped seals: All disassembled seals shall be rejected
and replaced by a new seal.
• Gaskets: After removal, always install a new gasket.
Apply a 0.125 inch (3.18 mm) diameter continuous
bead of silicone gasket material around one surface.
Also apply the gasket material around the edge of
all the fastener holes on that surface. Assemble
immediately and wait 20 minutes before fi lling the
assembly with lubricant.
!
CAUTION
Too much gasket material can block lubrication pas-
sages. Damage to components can result.
Recommended Lubricant: GRADE NLGI 2
During assembly:
• Verify the seal bearing surface edges are free of burrs
and nicks that may damage seals.
• Lubricate properly:
• Lubricate the entire interior surface of the ring
and primarily the seal lips.
• Pack the space between the lips with grease.
NOTE: Do not use an excessive quantity of
lubricant since liquefaction may occur during
operation and appear outside the housing. This
could easily be mistaken for a leak.
• The ring shall be engaged in its housing
perpendicularly and concentrically to the shaft.
• Do not damage the seal lips and turn them over during
installation.
Fasteners
When installing fasteners without pre-applied adhesive,
Loctite 243 Blue Threadlocker must be used unless other-
wise stated.
Product characteristics:
• Color: Pale blue
• Temperature Resistance:
-67 to 302°F (- 55 to 150°C)
• TO BE USED WITH CARE:
Avoid any contact with eyes and skin.
During disassembly:
• In the event of sticking, heat the screws.
• Clean excess material off all surfaces as thoroughly as
possible.
• Clean and carefully degrease surfaces (any lubricant
prevents setup therefore making the product
ineff ective) using a solvent or by washing the parts.
• Let all components dry completely.
During assembly:
• Apply one drop to the threads, preferably at the end of
the screw, of Loctite 243 Blue Threadlocker.
• Assemble the parts and tighten to the required
torque.
• All screws shall be tightened within 5 minutes
following assembly of the parts. The unit can be used
10 minutes after assembling.
NOTE: To reduce setup time, spray Loctite 7649 Locquic
Primer N activator on the threads, allow to evaporate, and
then apply Loctite 243.
Mounting Surfaces
For all mounting surfaces that do not use an o-ring seal,
use Loctite 5699 RTV Silicone Gasket.
Product characteristics:
• Color: Grey
• Adhesive power: Weak, nevertheless, do not use on
centering; only on the faces.
• Temperature Resistance:
-67 to 392°F (-55 to 200°C)
• TO BE USED WITH CARE:
Avoid any contact with eyes and skin.
During disassembly:
• In the event of sticking, tap the parts to break the
Loctite fi lm.
• Remove particles of Loctite as thoroughly as possible.
• Clean and carefully degrease surfaces (any lubricant
prevents setup therefore making the product
ineff ective) using a solvent or by washing the parts.
• Let all components dry completely.
During assembly:
• Apply a single bead to one of the mating surfaces well
around the attachment holes.
• Assemble the parts and tighten to the required
torque.
• Leave to dry: Parts can be handled after 30 minutes.
• Total setup time: 18 to 24 hours
