Go to “General machining sequence”.
If using Fixed Clamping Pads; P/N 26-0537, 26-0539, 26-0543, or 26-0545, the
following procedure must be used for mounting them into the Housing of the Model
601SBM Clamshell.
Insert the Screw (P/N 33-1305) into the housing from the outside with a blade type
Screwdriver to the depth shown in “Fixed Pad installation”.
Slide the Fixed Clamping Pad into the groove and while retaining the screw with the
Screwdriver, secure the Clamping Pad to the Screw using a hex wrench.
If using the fully Adjustable Clamping Pads, clamp the Clamshell to the pipe as
follows.
Rough center and square the Clamshell by tightening the four Clamping Pads
independently.
Check the center and squareness by eye.
The Adjustable Pads tend to square the Clamshell to the pipe.
If additional precision in squaring is required, consult Tri Tool about alternate
methods of squaring.
Fine center the Clamshell as you would a 4-jaw check.
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.
