Follower
If follower foam appears to be damaged or
does not wipe sides of reservoir effectively
service may be necessary († fig. , page 
and fig. IPB , page ; or fig. IPB ,
page ).
 Disconnect electric supply from pump.
 Remove bolts (), eyebolts () and lock
washers () which attach cover () to
reservoir assembly ().
 Lift pump (), vent valve () and drum
cover () out of reservoir ().
 Remove cable assembly () from fol-
lower assembly ().
 Remove follower assembly from reser-
voir assembly.
 Wipe off excess grease from follower
assembly.
 Loosen and remove nuts () on top of
follower assembly.
 Remove weighted follower plate () and
follower foam ().
 Replace with new foam.
 Remove and save spacers () from
inside of foam before discarding foam.
Reverse above procedure to re-assemble
making sure long bolts () are staggered
with small ones ().
NOTE
Do not bend housing tube during
removal of pump, vent valve and drum
cover.
Mechanical low level
indicator
Indicator seal () may be damaged if indi-
cator pin appears to drop prematurely or
water is noticeable on top of follower,
(† fig. , page  and fig. IPB ,
page ; or fig. IPB , page ).
 Remove bolts (), eyebolts () and lock
washers () which attach cover () to
reservoir assembly ().
 Inspect reservoir gasket seal () for dam-
age. If damage is apparent, replace gasket.
 Remove entire pump, vent valve and fol-
lower assembly from reservoir.
 Remove retaining ring () from indicator
rod assembly ().
 Hold indicator plug () with wrench while
removing indicator nut ().
 Remove and replace o-ring ().
 Reassemble in reverse of above
procedure.

Safety unloader valve
Safety unloader valve () († fig. IPB ,
page  or fig. IPB , page ) is not
serviceable. Replace if malfunction is
apparent. Upon reassembly, tighten to
 ft-lbf (13.5 Nm).
Safety unloader valve () is set to open at
  to   psi (258 to 293 bar) lubricant
pressure. If pressure switch fails to operate
and shut off hydraulic supply to pump, safety
unloader will open at approximately
  psi (275 bar) to relieve lubricant
supply line pressure (safety unloader is
preset and not adjustable).
Automatic
mechanical shut-off
Refer to manual  for automatic
mechanical shut-off.
Bare pump assembly
Refer to manual  for bare pump
assembly ().
