The splines shall be lubricated with hydraulic
oil, or filled with transmission oil from the con-
nected gearbox. To avoid wear in the splines,
the installation must be within the specified tol-
erances in table 3.3. If there is no radial or axial
force on the shaft, the shaft can be oiled only.
For production of the shaft, see 278 2230,
278 2231, 278 2232, 278 2233, 278 2234, 278
2235, 278 2236, 278 2238 and 278 2239. For
control of spline see table 3.3.
To make it easier to mount the motor on the
driven shaft end or to remove the motor from
the shaft it is recommended that a hole (table
3.4) should be drilled and tapped in the cen-
tre of the shaft for a mounting tool; see 3.1.4
"Mounting the motor onto the driven shaft",
and 3.1.5 "Removing the motor from the driven
shaft".
The tool has both a UNC thread and a metric
thread, so that the hole can be drilled and
tapped to conform to one of the two alternatives
given in table 3.4.
