Two Locking Screws are located on the Housing and two more on the Headstock.
Refer to ‘Locking Screw locations’.
These Locking Screws are captured in their holes so that they will not come totally
free of the Clamshell.
Separate the Clamshell halves evenly by pulling straight apart.
DO NOT FORCE OPEN.
SECURE THE CLAMSHELL TO THE PIPE.
Clean the mating surfaces and the ID of the Clamshell halves.
Wipe clean the mounting surface of the pipe.
Check to ensure that the Tool Blocks will clear the pipe when the Clamshell is
mounted.
Close the two halves of the Clamshell around the pipe, keeping the mating surfaces
clean.
Check that the Alignment Pins have seated the two halves properly.
Bolt the two halves of the Clamshell together using the Locking Screws in the
Housing and in the Headstock.
Tightening torque should be 35 to 40 ft-lbs. (47 to 54 N-m).
If using Fixed Clamping Pads, clamp the Clamshell to the pipe as follows: if not, go
to “If using fixed Clamping Pads, P/N…” (See the following).
Tighten the Adjustable Pads lightly so that all four of the Clamping Pads contact
the pipe.
Gently rock the Clamshell as you tighten the Adjustable Clamping Pads to seat the
Clamshell square on the pipe.
Check that all four Clamping Pads fully contact the pipe.
If not, repeat the last three steps.
Tighten the Clamping Pads.
Tightening torque should be 40 to 50 ft-lbs. (54 to 68 N-m).
