8.0 SET-UP AND OPERATION
8.1 MOUNTING THE FRICTION DRIVE GUIDE RING
(P/N 103040-XXXXX)
8.1.1 Adjust the tensioning screw on the "hinge side" of the guide ring so there
is approximately ½" (13mm) space between the tab and the slot of each
rail.
8.1.2 Open the guide ring and place it over the top of the pipe with the
tensioning screw heads facing you. (Hinge at 12 o'clock position.)
8.1.3 Position the feet of the guide ring approximately 6.875" (175mm) from the
center of the weld joint.
8.1.4 On the "latch side" of the guide ring (latch at 6 o'clock position), install the
catch bar into the receiver block. (Loosen the latch side tensioning
screw, if required.)
8.1.5 Tighten the latch side tensioning screw. (Approximately 10 inch/pounds
or 1.13 N-M).
8.1.6 If the tab/slot gap is significantly different between the hinge side and
latch side of the guide ring, readjust the tensioning screws to balance the
gap.
8.1.7 If the two dovetails are not the same radius as the guide ring (see sketch
below), the tractor may hesitate or stall as the rollers cross the joint. This
can be corrected by careful use of a hammer or heavy pliers.
8.2 INSTALL WELD HEAD ON GUIDE RING
8.2.1 The Pipeliner II Head is mounted on the pipe by rotating four hardened
steel rollers under the steel edges of the circular guide ring or Flx-Track.
These are spring-loaded with an internal spring to provide the load to
firmly engage the V-rollers with the V-belt. (The rim is pinched by the
action of the steel roller and V-rollers or the Caliper Actuator.) The spring
loading of the four rollers must be released to remove the weld Head.
Two options are available to accomplish this:
A. Push-button pneumatic release (standard)
B. Manual thumb screw release
Both methods of actuation include a rotary cam function. As the spring
load is reduced to zero, the rollers are simultaneously pivoted outward
from under the steel rim, allowing the Head to be removed.
