Model 648SB Low Profile Clamshell (2 Piece)
92-1146 : Rev. 131230
WARNING:
CAUTION:
Fine center the Clamshell as you would a four-jaw chuck.
Take measurements from the pipe OD to the Housing ID or use a dial
indicator to sweep around the pipe’s outside diameter.
Adjust the four (4) Clamping Pads so that the measurements at opposing
Clamping Pads are the same.
Tighten the Clamping Pads using a tightening torque of 25 ft-lbs (34 Nm) to
30 ft-lbs (40.7 Nm).
Tighten the Jackscrews against the pipe using a tightening torque of 15 ft-lbs
(20.3 Nm) to 20 ft-lbs (27 Nm) for added stability.
GENERAL MACHINING SEQUENCE
Install the Hydraulic Motors into the Drive Sprockets and bolt them to the Clamshell.
The Motor Mount reacts to the torque of the Hydraulic Motor only when the
Motor Hold-down Bolts are in place.
Rotate the Headstock slowly with the Tripper Shaft pushed ‘in’ for one full revolution
to insure that the Feed Pin to Sprocket is set right on both Tool Blocks.
Approach of the Feed Pin to the Feed Sprocket
You will break the Feed Pin if the Feed Pin to Sprocket Alignment is incorrect.
To check the Feed Pin to Sprocket engagement go to the ‘Feed Pin to Sprocket
Engagement’ information later in this section.
Select and Install the desired Tool Bit Set.
