We developed a spinner assembly compatible with TM 80 and 120 wrenches.
Spinner failure is a constant problem due to multiple design flaws.
Bearing failure, loose fit on shafts, sprung frames, inadequate bearings, and brass roller washers.
T&J Super Spinners are designed to eliminate all these problems.
The 5-piece bolt together design makes for easy replacement of any one damaged part.
Over-sized spinner shaft to increase load capacity and insure proper alignment.
5.75 main roller body protects gear box and spinner frame while allowing 100% contact with drill pipe.
Chevron pattern roller is heat treated for longer life with less chipping.
Replaceable composite roller bushings eliminate roller bearing failure.
Composite Input gear bushing eliminates metal on metal wear and bearing failure.
Lessens likelihood of spinner frame damage.
Replaced brass washers with a composite plastic thrust washer, which are full size of roller body and can utilize drilling fluids for lubrication.
Spinner pivot pin bushings are easily replaced insuring proper alignment.
Easily accessible.
With the addition of a grease bulkhead the spinner can safely be greased from one location away from any pinch points.
If spinners are only being used periodically throughout the day, they require grease every 12hrs. When tripping Spinner bushings should be greased every 20 joints.
Four pumps on top bushings and gear box. Then grease bottom bushings until grease comes out of the bottom.
Every two weeks it is T&J’s recommendation to inspect bushing wear by placing a flat bar between rollers and check for side to side movement. If there is more than an 1/8th inch of play, the bushings need to be replaced. Also, check for vertical movement by placing bar under each roller and lifting up. If roller moves more than a 1/16th of an inch the bushings and thrust washer need to be replaced. This is necessary in order to extend spinner life. Not replacing bushings in a timely manner may result in unrepairable damage to the spinner frame.
When replacing spinner bushings you must disassemble spinner frame and remove rollers. Remove ORB plugs from bottom plate and a 5/16 (24) fine thread bolt can be used as a pusher bolt or use a small punch being sure not to damage threads. Once removed clean bushing housing and coat surface with clean grease before pressing new bushings in. Be sure new bushings are flush. Press out top bushings, clean housing and coat with clean grease and press in new bushings making sure they are flush. Be sure to replace thrust washers before placing rollers back in the spinner frame. And be sure to replace ORB plugs in bottom plate.
If roller shafts appear to be to tight of a fit in the bushing, you may have to hone bushing ID with an emery cloth or flapper wheel to ensure proper fit.
