Step 14.
Install reducing tap plug
• Clean and lubricate the mating interfaces of T-Body and
reducing tap plug (BLRTP).
• Insert BLRTP into the back of the T-body, engaging the
threads of the stud. See Figure 27.
• By hand, turning clockwise, thread BLRTP in as far as
possible.
• Using a 3/8” drive torque tool and HD625 (5/16” hex
shaft), complete threading clockwise until tight. Torque to
55 ft-lbs. See Figure 27.
Step 15.
Check tightness of termination
• Check tightness by hand by moving the T-body forward
and back (perpendicular to the apparatus frontplate). Do
not move side to side as this may loosen the connection.
• If tight:
• Re-torque to 55 ft-lbs.
• If loose:
• Remove BLRTP and T-body from the apparatus bush-
ing.
• Inspect threads of the stud and BLRTP for damage.
If damaged, replace the damaged component and re-
install per previous installation instructions.
• If no damage is found, re-install per previous installa-
tion instructions.
