The Insert bowl is designed per API Specification 7K. There are 3 typical sizes of insert bowls used in drilling applications: API#1 Insert Bowl 13-3/8 ~ 11-3/4 pipe or tubing API#2 Insert Bowl 10-3/4 ~ 9-5/8 pipe or tubing API#3 Insert Bowl 2-3/8 ~ 7-5/8 pipe or tubing

PAGE 5 IV. INSTALLATION This manual is provided for guidance of the basic required service for minor adjustment and product service. This information is not elementary. Any major overhaul or adjustments must be performed by a certified company in the repair or remanufacture of rotary tables. TO PREVENT PERSONAL INJURY during maintenance and inspection, this equipment must be shut down and not operating. Employ good mechanical practices when making maintenance repairs, adjustments, inspections, etc. This item is allowed a maximum 8 decibels while in service. Appropriate hearing safety device should be worn at all times to prevent hearing loss. 1. The rotary table must keep horizontal in the process of assembly and the sprocket must be in alignment with that of the gear train 2. All parts must pass acceptance examination. Parts must be washed and rid of all burrs. 3. The rotary table must be supported by flat rotary beams and anchored in place to maintain proper alignment with the prime mover. There should be adequate clearance around the frame to prevent a build-up of drilling mud and to allow the table to be washed periodically. 4. Adjust shim thickness between the bearing cover of input shaft and base frame to acquire the specified clearance: 0.34mm to 0.76mm between the gears. 5. All air tight packing must be manually fixed 6. As the new rotary table is emptied of the oil, thoroughly rinse the rotary table before operation and fill with oil in accordance with the requirement. 7. Rotate the sprocket a minimum of 40 after assembly to ensure no clogging and smooth rotation occurs. V. LUBRICATION 1. The entire internal mechanism of the rotary machine, including the inner and outer pinion bearings is lubricated from the main oil reservoir by splash. Oil is lifted by the pinion and directed by means of troughs and deflector pans.

PAGE 6 2. It is essential the oil level is monitored and kept within the HIGH and LOW markings on the dipstick. About 30 L max capacity. 3. STOP ROTATION of the table when checking oil level. Use an extreme pressure, non-corrosive, anti-foaming gear lubricant as follows: Ambient temperatures: 0F to +155F (-18 to 68C) AGMA #6-20F to +40F (-29C to 4C) AGMA #4 Grease Fittings: 0F to +125F (-18C to 68C) NLGI #2-20F to +40F (-29C to 4C) NLGI #0 Approved BP Products for above specifications: AGMA #6 Energol GR-XP 320 AGMA #4 Energol GR-XP 105 NLGI #2 Energrease MMEP 2 NLGI #0 Energrease MMEP 0 VI. MAINTENANCE Periodic 1. Check the level of lubrication oil by means of the dipstick once each shift to ensure the full lubrication of the rotary table. The table must be stopped to perform this task. Any radical change in oil level over a short amount of time should be investigated; this may be caused by leaking seals, loose drain plugs, or water or mud entering the reservoir. 2. The grease fittings of the lock paws must be filled with grease once in a shift. The fittings are accessible when the lock paws are engaged in the lock position. Monthly 1. Open the top cover to clear away the mud that may have accumulated in the frame. 6. Change the lubrication oil after operation of a new rotary table in 30 days. From then on, the oil should be changed in 3 month intervals, or when poor oil quality is found. 7. Bearings must be changed at 80% of L-10 life. Periodically inspect the bearings conditions every month or of 100 hours of use.

PAGE 7 Each 3 Months 8. Drain the oil reservoir. Add diesel fuel or light oil to the MAX FILL line on the dipstick and rotate the table at rate of 40-60 RPM for 1 minute. Drain flushing oil and replace with required oil for normal operation. Yearly 9. Check the upthrust clearance of the main bearing and the backlash clearance of the gear set. At the same time check the axial clearance of the pinion bearings. 10. Remove the gear table from the frame and inspect all parts for any normal or abnormal wear. Replace and make adjustments as necessary. VII. PACKING & DELIVERY 1. Rust-prevention treatment should be carried out for all bearing surfaces, gears, etc before packing. 2. The carry-in shaft key should be fixed onto the shaft. Protect the input shaft to avoid impact damage. 3. Cover the top of the rotary table with plastic to prevent water from entering the rotary table.
