Before initial
operation the Driveshaft must be greased using Lithium based
grease with E.P. additives. The maximum greasing pressure is
15 bar.
TRANSPORTATION
& STORAGE
Since Driveshafts are manufactured as high quality products,
they may suffer damage due to improper storage and transport,
which could render them unusable.
The original NDE Clarke packing is only suitable for despatch
and a short term storage. The Driveshafts should be stored in
dry and weather protected areas. If the Driveshaft is to be stored
for a long period, the Flange connecting faces should be treated
with an anti-corrosion agent.
Transportation should be carried out with the Driveshafts in
a horizontal position. If the Driveshaft is put in any other
position than horizontal, it is essential to prevent the spline
elements from sliding apart. This, and the tilting of the joints
may cause personal injuries. Any impact must be avoided.
For the transportation of the Driveshafts we recommend the use
of nylon ropes. The following sketch indicates a reasonable method.
INSTALLATION
For the installation of the Driveshafts, the following instructions
must be observed:
Check before immediate installation for possible transit damage.
Driveshafts which have been stored for a long time should be
regreased in working conditions before they are put into operation.
When spray painting the Driveshafts, make sure that the area
in which the Spline or the Seal glides is protected from paint.
The faces of the Flanges must be free from anti-corrosion agents,
paint, grease and dirt.
Do not rotate the Driveshaft with assembly levers in the Joint
because this may cause damage to the Joints, Grease Nipples or
Air Relief Valves, where fitted.
Nuts and Bolts of the correct size should be evenly tightened
crosswise all round until securely locked to the recommended
torque value. The Bolts should only be slightly oiled. Lubricants
containing MOS2 additives or similar
must not be used.
Check the position of the Yokes (1) according to drawing and
ensure arrows are in line
(2) see below.
Before initial
operation the Driveshaft must be greased using Lithium based
grease with E.P. additives. The maximum greasing pressure is
15 bar.
Connecting Flanges must be checked for concentricity, radial
runout and fit to Shafts.
IMPORTANT
Guards - Rotating Shafts and Joints must be guarded to eliminate
the possibility of physical contact or entanglement of clothing.
It should be of rigid construction and firmly secured.
INSPECTION & MAINTENANCE
Driveshaft inspection should be carried out at regular intervals
and it would be reasonable to co-ordinate this with the maintenance
work on other Vehicle parts. The maintenance intervals mentioned
in the following section are only recommendations because maintenance
intervals generally depend on the operating conditions of the
Vehicle and on practical experience.
Driveshafts are used in a great variety of Industrial plants
with very different operating conditions. We recommend inspections
at regular intervals and, if possible, coordinate it with maintenance
work on other parts of the equipment. However maintenance work
should be carried out once a year at least.
Check the Flange Bolts for tightness and retighten them with
the prescribed torque. If they need replacing, Nuts and Bolts
of the correct size should be evenly tightened crosswise all
round until securely locked to the recommended torque value.
The Bolts should only be slightly oiled. Lubricants containing
MOS2 additives or similar
must not be
used.
Check lubrication schedule is being maintained.
Backlash inspection. By lifting the Driveshaft check the Joint
and the length
compensation
for visible or tangible backlash. If there is any perceptible
play, the
Driveshaft
must be repaired.
Check the Driveshaft for any unusual noise, vibration or abnormal
behaviour and repair the damage, if any.
BOLTING
All inspections must include the checking of the Bolts for the
prescribed tightening torques.
The Bolts should only be slightly oiled. Lubricants containing
MOS2 additives or similar
must not be used. The Driveshaft should be greased with a Lithium
based Grease with EP additives.
Grease Nipples must be cleaned before greasing.
The maximum greasing pressure is 15 bar.
There are three greasing areas on the Driveshaft, the Universal
Joints and the Splined Sleeve.
IMPORTANT
When lubricating Universal Joints, ensure that fresh Grease exudes
from all four Bearing Seals to be certain that all Bearings have
fresh Grease. The lubrication of the Splined Sleeve should be
carried out with the Driveshaft fully compressed to prevent excessive
axial force developing.
RE-GREASING
INTERVALS
Recommended regreasing intervals (unless otherwise specified
by the manufacturer of the Vehicle). The following maintenance
intervals refer to European and comparable conditions. Other
conditions may require shorter re-lubrication intervals.

The recommended
lubrication interval for Driveshafts used in Industrial plants
in normal operating conditions is three months. Unfavourable
effects like temperature, dirt and water may necessitate shorter
lubricating intervals. We recommend adapting the lubricating
intervals to the individual operating conditions.
