unit, the filter element may be clogged. Change
the filter element.
 Make sure drive rollers are not touching each other
when gripped on drill pipe. Adjust Pipe Size pg.14.
 Spinmaster chain may be rusted. Check to see that
it is flexable and free to move. If the chain needs
attention, See Maintenance and Repair pg.19,23.
 Check that the drill pipe connections are within API
tolerance.
 The drive roller sprocket bearings could be worn
out. Check that they are turning freely. Replace
them if neccessary. See Maintenance & Repair
pg.27. Note: Extreme bearing wear could cause
bearings to spin on their inner or outer raises
making it difficult to remove from their mounting
possitions. Replace the drive roller sprocket if
neccessary. See Drawings Pg.50,54
 Check the drive roller wear. If the drive roller
groove is no longer visible, replace the drive roll-
ers. See Maintenance & Repair pg.25.
 The bottom drive shaft flange bearing is worn out.
Replace it. See Drawings pg.50,54.
 The drive and/or roller sprockets could be worn
enough to cause a reduction in performance.
Check for irregular shape to the sprocket teeth.
For changing sprockets see Drawings pg.50,54.
 The reducer could need some attention. If properly
lubricated, the reducer is a long term wear item.
If all other rotating members on the spinner work
correctly, inspect the gears and bearings in the
reducer for wear. Replace where neccessary. See
Drawings pg.60.
 The hydraulic drive motor could be tired. With
properly filtered hydraulic fluid, the drive mo-
tor is a long term wear item. If all other rotating
members on the spinner work correctly, inspect the
drive motor rotating group, bearings and seals for
wear. Replace where neccessary. See Drawings
pg.62.
 The spinner is adjusted too large for the drill pipe
The Spinner torque is insufficient
to rotate the drill pipe stand. (Con-
