DESCRIPTION This Hybrid Technology Universal Top Drive Lifting Cement Head was designed from its inception for use in a top drive system. While it is relatively light and compact, it has the highest lift/pressure rating in the industry. Its optional subs add considerable versatility. The Top Drive Universal Lifting Cement Head allows the continuous and independent rotation, stroking (lifting) and high flow cementing simultaneously. Plugs can be loaded before the job and dropped by a manual or remote pin puller, without using a manifold. Slots in the Plug Cage allow the direct pressure on the bottom Plug from the flow passing the Cage to guarantee launch after the pin on the pin puller is retracted. The flow from circulation then cleans the Head from the cement. head is designed so that ample annular area exists around the largest size Cage to allow fluid flow at a reasonable velocity. The Plug cages use an adjustable length standoff/spring expeller to ensure the dart is pushed into the fluid flow for launch. A spring loaded, lever operated tattle tale releases a flag to indicate dart passage. It can be recocked without removal from the head. Both hook load and combined hook/pressure load capacities are increased by the one piece integral design. This no-weld construction contributes to the head s simplicity, compactness and lightness. The Sure Lock system has the ability to customize jobs with minimal inventory by changing the cage and the bottom sub only. The cement head uses a flow around design that keeps the plug out of the fluid path. Variable size Cages are available depending on which launching Plug is being used. The PAGE 2
OPERATION All standard operating procedures for flow rates and pump pressures apply when using the Hybrid Universal Lifting Cement Head. The Plug may be released without interruption of circulation flow. Please Note: the plug cannot freeze to the cage because it is naturally warmed by the flow of the circulation fluid temperature. Release of the Plug The Cage By cementing plug is released from the Cage by pin puller assembly. To release, unlock the safety and turn and the bonnet to the left (counterclockwise) approximately nine (9) turns. Right hand threads are used. The indicator pin will show in the bonnet at the end of the stroke. Inside the Plug cage, a captive expeller spring pushes the plug into the fluid flow. Tattle Tale The passage of the dart from its cage into the drill string is indicated by the Lever/Flag Tattle Tale. A lever extending into the head bore releases a spring-loaded arm to display a stored flag. The arm stroke is 3 in/76mm. The Tattle Tale assembly is recocked without removal from the head. To re-cock, push end of indicator arm in and hold. With a probe thru top hole, push indicator head into latch. Roll flag up, push between guard and arm. PAGE 3
SERVICE AND ASSEMBLY General Wash, dry and oil all parts. Inspect for damage. Particularly inspect O-Rings and backups for nicks or cuts. Pre-grease grooves before installing O-Rings and backups (if gland is assembled dry, something else besides grease will fill the groove). Body and Plug Cage Plug Cage is held in place in the body by the lips on the front edges of the pin dropper. The cage can only be assembled in one position. Ensure that the plug puller and plug are in their proper position. Note their names are stamped their proper port on the body. Screw into body until the front lips catch the tube of the plug cage and the shoulders make up. Set lock nuts with moderate tap of a hammer. Upper Swivel Sub Disassembly after every job is not required, if no leaks were observed from the bleed holes during the previous job. Wash circular section thoroughly. Grease each fitting until grease appears at opposite bleed hole. Rotate several times and lightly regrease. Use finger to plug bleed hole while lightly regreasing to force grease through bearing and through seal. Be sure to grease O-Ring land above Sure-Lock. If leaks were observed during operation, swivel must be disassembled for seal replacement and to clean bearings of possible contamination. Be sure to install wiper ring on body before installing the flow ring. The split (2 piece) keeper ring is used on the bottom side of the flow ring. Reaction plate #8 may be assembled to top or bottom or swivel in any convenient position. On assembly, be sure seal lips face each other. Grooves and shoulder have been angled to allow easy assembly. However, on disassembly it is easy for the lower seal lip to catch the upper lock ring groove. Remove the upper bearing and cover the groove with tape or a metal shim to make sliding the seal easy. Install 1502 adapter with lock nut loose. Set the lock with hammer and chisel, medium tight. PAGE 4
Pin Puller Disassembly not required unless bonnet is stiff to turn or seals leak. 1. Retract Screw Pin #21 2. Grease 3. Extend 4. Grease lightly Sure Lock Body Adapter Lube O-ring and land, be sure camlocks are turned flush, and assemble. When box is fully down over pin Sure Lock, rotate 60 to the right. Secure the Sure Lock by turning the 3 camlocks one half turn to the right (clockwise) with a 5/16 allen wrench, as pictured below. Lever Tattle Tale Disassembly not required unless lever is stiff to operate or seals leak. Unlocked Locked PAGE 5
