to the shoulder, or Spinner
performance and speed not up
to par. (cont.)
HawkJaw performance and
speed not up to par. z
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, p.35.
z
Check the lead-in pressure and tank lines for any
obstructions. Also check the quick disconnects

z
The filter element is clogged. Replace the
filter element. See Maintenance & Repair, p.
35.
z
The air pressure is low. Increase the air
pressure to the HawkJaw. See Installation, p.
12.
z
The hydraulic pressure is low. Increase the
hydraulic pressure. Do not increase the
pressure over 2500 psi, or the hydraulic fluid
will pass over the relief valve and heat up the
hydraulic fluid. This will cause damage to the
HawkJaw and to the pump, and will severely
shorten component life.
z
Check to make sure the hydraulic power unit
is producing 2500 psi at 20-35 gpm.
z
Check to make sure the hydraulic power unit
pressure compensator setting is at 2500 psi.
z
Check that the drill pipe connections are
within API tolerance.
z
The Drive Roller Sprocket Bearings are
worn out. Replace the Drive Roller
Sprocket Bearings. See Maintenance &
Repair, p. 53-54.
z
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.
z
The Drive Rollers are worn out. If the Drive
Roller Groove is no longer visible, replace
the Drive Rollers. See Maintenance & Repair,
p. 51-52.
z
The Bottom Drive Shaft Flange Bearing is worn
out. Replace the Flange Bearing. See Draw-
ings, p. 104.
z
The Reducer is worn out. If properly lubri-
cated, 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, p. 144.
z
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, p. 146.
