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 personnel 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.
