Hawkeye Shear Couplings - Manual

This document contains the recommended procedures installing a Hawkeye Industries Inc. Sucker Rod Shear Coupling.
Tool and Hole Preparation
Coupling Preparation
1.) Install all downhole equipment per manufacturer’s directions.
2.) Calibrate all tooling and installation equipment, and ensure equipment
is in proper working order.
The Shear coupling can be oriented box-down, or box-up with no
effect on performance. The following is for box-down installation,
and assumes a sucker rod pin connection is looking up. Do not
use a polished rod thread form in the shear coupling box.
Installation Instructions
Sucker Rod Shear Coupling
Shear Coupling Instructions, July 2010 1
1.) Remove thread protection from the
box and pin, and ensure both
threads are clear of debris, and are
free from damage and corrosion. If
there is damage or corrosion on the
threads, do not use the shear cou-
pling.
2.) Apply an appropriate and approved
sucker rod thread lubricant to the
coupling threads, taking care to de-
grease the pin shoulder and coupling
face to remove thread lubricant.
1.) Carefully place the shear coupling box onto the rod pin and start the
first thread by hand.
2.) Use a rod wrench to turn the shear coupling until the box flat and
sucker rod pin shoulder touch.
3.) Use the sucker rod manufacturer’s power tong make up procedure
for final tightening, taking care not to exceed the published maximum
torque rating of the shear coupling.
4.) Carefully place the coupling onto the shear coupling pin and start the
first thread by hand.
5.) Use a rod wrench to turn the coupling until the shear coupling pin
shoulder and coupling face touch.
6.) Use the sucker rod manufacturer’s power tong make up procedure
for final tightening, taking care not to exceed the published maximum
torque rating of the shear coupling.
7.) Carefully insert the sucker rod pin into the coupling and start the first
thread by hand.
8.) Use a rod wrench to turn the shear coupling until the box flat and
sucker rod pin shoulder touch.
9.) Use the sucker rod manufacturer’s power tong make up procedure
for final tightening, taking care not to exceed the published maximum
torque rating of the shear coupling.
Joint Make-Up
1 - 3.)
4 - 6.)
7 - 9.)
Complete
► Ensure the shear coupling does not reside in areas of
heavy deviation
► Ensure the shear coupling is not in a position to receive re-
versible (cyclic) bending, and is at least one joint above the
pump.
► Ensure the shear coupling is not in a position to receive
considerable combined (tension + torsion) loading.
