C. PERIODIC INSPECTION AND MAINTENANCE
1. Inspection
The torque measurement system supplied with your equipment is designed and built to provide years of trouble-free service
with minimum maintenance. Periodic inspections of the load cell, hydraulic lines and fittings are recommended in order to keep
the system in top operating condition. A thorough inspection should be made at each rig-up.
2. Fluid Recharge
Recharge hydraulic system with W15/16 fluid through the check valve on the torque indicating gauge. Recharging must only be
performed when there is no load on the load cell. Refer to the illustrations on pages 6.3 & 6.4 for guidance if required.
a. Place the torque indicating gauge higher than the load cell. Remove the brass 1/4” cap from the fitting on the check valve
on the top of the gauge.
b. Connect the hand pump to the check valve fitting.
c. Elevate the load cell so it is higher than the torque gauge and hand pump.
MAINTAIN GREATER-THAN HALF FULL FLUID LEVEL IN THE HAND PUMP BOWL TO AVOID
PUMPING AIR INTO THE SYSTEM. DO NOT ALLOW THE LEVEL TO FALL BELOW ONE-HALF FULL
UN-CONTAINED SPILLAGE OF THE HYDRAULIC FLUID IN THIS SYSTEM MAY CONTRAVENE
GOVERNMENTAL ENVIRONMENTAL REGULATIONS, OR THE ENVIRONMENTAL REGULATIONS
AND POLICIES OF YOUR COMPANY. MCCOY DRILLING & COMPLETIONS HIGHLY RECOMMENDS
PLACING YOUR LOAD CELL IN A CONTAINMENT BASIN BEFORE PROCEEDING WITH THE
BLEEDING & REFILLING PROCESS.
d. Fill hand pump bowl with W15/16 hydraulic fluid.
e. Remove the vent plug screw and Stat-O-Seal (Items C and D on Illustration 6.A.4, or item H on Illustration 6.A.5) to allow
trapped air to escape.
f. Pump fluid into the system until no more air is seen escaping from the vent port.
g. Replace the vent plug screw and Stat-O-Seal and tighten securely.
h. Remove load cell from containment vessel and wipe clean. Reclaim the hydraulic fluid (if it is clean) or dispose of all
waste materials according to governmental or your company’s proscribed environmental protection regulations.
i. Disconnect the hand pump from the torque gauge.
j. Replace the brass cap on the torque gauge check valve fitting.
3. Repair And Calibration
Load cell and indicator gauge should be returned to authorized repair facility for any repairs or calibration required.
