Remedy
•
On long drill pipe tool joints of 10" or more it
may be neccessary to remove the top wrench
heel die when breaking out drill pipe or the bottom
wrench heel die holder win making up drill pipe.
To do this first remove the quick release pin and
slide out die. Make sure to grease the die holder
when replacing.
•
The Drive Rollers are worn out. If the Drive
Roller Groove is no longer visible, replace the
Drive Rollers. See Maintenance & Repair.
•
The Bottom Drive Shaft Flange Bearing is worn
out. Replace the Flange Bearing. See Drawings.
•
The Reducer is worn out. If properly lubricated,
the reducer is a long term wear item. If
all other rotating members on the spinner work,
inspect the gears and bearings in the reducer for
wear. Replace where necessary. See Drawings.
•
The Drive motor is worn out. With filtered
hydraulic fluid through a Hawk approved filter,
the Drive motor is a long term wear item. If all
other rotating members on the spinner work,
inspect the rotating group, bearings and seals
for wear. Replace where necessary. See Drawings.
•
Check that the hydraulic filter element is not
completely full of contaminants. If the red
indicator button on the hydraulic filter body
pops up, change the filter element. See Filter
Maintenance.
•
Check the lead-in pressure and tank lines for
any obstructions. Also check the quick
disconnects.
