Our universal drivelines are delivered ready for installation. If not otherwise specified by the customer, they are balanced dynamically at n = 2000 RPM according to classification Q 16 of the VDI recommendation 2060.

To retain the high degree of balance, the drivelines must
be protected during transportation or storage from blows or jolts. It is recommended to transport them in horizontal position. When transporting them vertically, appropriate measures must be taken to avoid separation of the driveline halves. A horizontal position is also preferred for storage of the driveline, since doing so eliminates tipping over and possible damage. Never store drivelines on the floor, but if possible, on wooden shelves. At prolonged storage, blank metal parts must be checked for corrosion, and if necessary, treated again with a corrosion inhibiting oil.

This drivelines should be arranged such that the spline, whenever possible, is protected from dirt and moisture. As a rule, this means installing the driveline according to the sketch above, where the spline seal points downwards so that spray water hitting it runs away from the spline.

Before installing drivelines, all traces of rust inhibitor, dirt and grease must be removed from the flange surfaces to preserve the coefficient of friction vital for torque transmission.

Drivelines should not be separated at the splines and the halves interchanged, otherwise the quality of balance is greatly impaired.
For the same reason, balance plates should not be removed.
Prior to installing drivelines, it must be checked that they are assembled correctly, which means that the marking arrows on the splined shaft and splined hub must face each other (See also notation on Page 170).

If two or more drivelines are arranged in series be-hind each other, it is recommended that they be mounted offset to each other by 90°. Doing so will at least partially cancel to the outside the effect of the mass acceleration forces caused by the fluctuation motion of the driveline center parts.

The necessary, bolting hardware for flange mount-ing can also be supplied by us on request. For bolt grades and necessary bolt torques, see page 74. When torquing down the bolts, if possible, a torque wrench should be used and the torque should be applied evenly in a crosswise pattern.

Our drivelines are delivered grease-packed, ready for installation. However, after prolonged storage, it is advisable to reapply grease before putting them into service.
