CAUTION: Excess lubricant collects grit and chips that can damage or jam the thread.
Set Timing of Tool Module and Tripper Sprocket
1.
Before mounting the Tool Module to the Head Stock, position the Tripper
Sprocket. The Tool Module has four possible mounting positions, refer
to Figure 7.
2. Determine the position of the Tool Module.
•
Position #1 is for the largest pipe the Clamshell can mount on.
• Position #2 is the next pipe size down and so on.
3.
Remove the two 1/4-20 Cap Screws from the Sprocket Block. Slide the Sprocket
Block and Sprocket to the correct position and reinstall the two 1/4-20 Cap
Screws.
4. Mount the Tool Module to the Head Stock.
1. Use lubricant sparingly on the Feed Screw or wipe to a film condition.
2.
Adjust the Adjustable Slide Rail until there is a firm, rotational pressure on the
Sprocket. You should be able to move the Sprocket with your hand, which is
about 12 in-lb (1.4 Nm) to 16 in-lb (1.8 Nm) of torque applied to the hex on the
front face of the Sprocket Assembly.
3.
After lubrication, tighten the Slide Rails to squeeze the oil into a thin film
against the male and female surfaces by doing the following:
a. Loosen the hold down screws.
b.
Tighten the adjustment set screws to more than 16 in-lb (1.8 Nm) of torque.
c.
Loosen the adjustment set to 12-16 in-lb (1.4-1.8 Nm) setting for normal
operation.
d. Tighten the hold down screws.

Refer to section 5.10 which has procedures for adjusting the tool module on
the clamshell.
