WARNING:
CAUTION:
Approach of the Feed Pin to the Feed Sprocket
Fine center the Clamshell as you would a 4-jaw chuck.
Take measurements from the pipe OD to the Housing ID or use a dial
indicator to sweep around the pipes outside diameter.
Adjust the four Clamping Pads so that the measurements at opposing
Clamping Pads are the same.
Tighten the Clamping Pads using a tightening torque of 50 to 75 ft-lbs.
(68 to 102 N-m).
Tighten the Jackscrews against the pipe using a tightening torque of 35 to
50 ft-lbs. (47 to 68 N-m) for added stability.
GENERAL MACHINING SEQUENCE
Install the Hydraulic Motors and the Drive Housings (if required) into the slots and
bolt them to the Clamshell.
The Motor Mount reacts the torque of the Hydraulic Motor only when the
Motor Hold-down Bolts are in place.
Connect the hydraulic power supply to the Model 620SB.
Rotate the Headstock slowly with the Tripper Shaft pushed ‘in’ for one full revolution
to ensure that the Feed Pin to Sprocket is set right on both Tool Blocks.
You will break the Feed Pin if the Feed Pin to Sprocket alignment is incorrect.
