11. Make sure that both seal ring housings (5) are in
correct alignment and that the seal ring housings
are concentric. Move the parts slowly and move the
parts carefully toward each other.
NOTE: Do not force the seal ring and the seal ring housing
together in a sudden manner. The seal component
could be scratched or the seal component could be
broken if the components are slammed together.
12. Tighten the bolts after the components are in the
correct position.
Acceptable Lubricants for Assembly
AVOID PROLONGED SKIN CONTACT WITH ISOPROPYL ALCOHOL.
AVOID BREATHING THE VAPORS IN ENCLOSED AREAS WITHOUT
ADEQUATE VENTILATION AND DO NOT SMOKE.
ISOPROPYL ALCOHOL IS FLAMMABLE. DO NOT USE NEAR OPEN
FLAME, WELDING OPERATIONS, OR AROUND HEATED SUR-
FACES EXCEEDING 482°C (900°F).
NOTE: Do not use any liquid that leaves an oil film. Do not
use any liquid that does not evaporate quickly. All of
the guidelines for safety and all of the guidelines for
disposal must be followed when you use a flamma-
ble liquid. The following liquids are acceptable lubri-
cants for assembly:
• Quaker Solvo Clean 68-0
• Houghto-Grind 60 CT
• Isopropyl alcohol
Some seal kits come with silicone toric rings. As an option
to using liquid lubricants to install silicone toric rings, the
rings can be chilled for easier installation. This will allow
the toric ring to contract for easier installation.
If chilling is desired, Seals should be placed in a freezer
for 5 minutes prior to installation. Temperature in the
freezer should be between -40°C (-40°F) to -18°C (0°F).
Contraction will be sufficient to allow installation. The
seals should be allowed to warm to room temperature
prior to further assembly.
