The lifting force established in steps 1 - 3 only needs to be done
for the first machine of the design type. Any significant changes
to the weight of the accessories added to the Pump Drive would
require that the lifting force be re-established .
Alignment - U-Joint-Type Installation
Alignment of In-line Drive “U” Joint Type
To realize maximum bearing life, the best possible alignment must be
maintained between the center line of the PTO shaft and the center line of
the pump drive. This may be accomplished as follows:
1. First, and very important, the forks (items 1 and 2, Figure 1) of the
drive shaft between the PTO and the gearbox must lie in the same
plane. This will prevent severe vibrations from occurring in the drive
shaft.
2. Second, the center lines of the PTO shaft and gearbox input shaft
must be offset within the limits recommended by the universal joint
manufacturer to prolong the life of the universal joint needle bearings.
3. Third, and very important, the center lines of the PTO shaft and gear
box input shaft must be parallel. This will further prevent vibrations
which cause premature bearing failure.
4. Proper lubrication of the gearbox clutch is very important for
satisfactory performance. The clutch bearings are lubricated with
lithium -based grease, NLGI-2 grease. The grease selected should be
recommended for anti-friction bearings and have a minimum melting
point of 149° C (300° F). A list of approved lubricants is available upon
request.
Alignment Measurement Procedure
The centerllines of the PTO shaft and input shaft of the pump drive
must be parallel. One method of accomplishing this is shown in Figure
1. To align engine and pump drive by this method, two accurate straight
edges that are at least 36 inches (860 mm) long, and a tape measure are
required.
