3-4. REPLACE/REPAIR PUMP ASSEMBLY (Continued)
WARNING
Death or serious injury could occur if unauthorized or
unnecessary personnel are in the hoisting area. Permit
only person-nel actually engaged in the hoisting
operation to be near the unit and hoisting equipment. All
instructions for the hoisting operations must come from
one authorized person.
Injury to personnel or damage to equipment could occur
from improper hoisting. Hoist the load slowly to avoid
tearing out lifting bail assembly, slipping slings, or load
shift. Do not jerk the load or swing it from side-to-side
when hoisting. This places additional stress on hoisting
components which can cause failure and loss of load.
Be sure hoisting equipment is on solid footing and is
suitable for the size of the load. Watch boom angle and
overhead clearance when hoisting.
6
Position a suitable lifting device equipped with a spreader bar and slings over pump assembly. Attach slings around
assembly and put tension on slings. Make sure pump assembly is properly supported. Spread slings on spreader bar
so that slings hang vertically when attached to assembly.
7
Lift and remove pump assembly from blocks on work platform. Lower carefully so that bearing housing assembly
alines with flywheel housing. Aline holes in coupling collar with drive pins on flywheel, and pump body mounting holes
with holes in pump mount beam. When these holes and pins are alined, slide pump and bearing housing assembly
toward engine so that flexible coupling mates and engages properly.
NOTE
Alinement of the flexible coupling and flywheel may be
checked and corrected by viewing through bearing
housing.
