Mounting the spline motor to the coupling adapter/driven shaft
The motor can be mounted to the driven shaft with or without a mounting tool,
but the use of a mounting tool is recommended since it makes the work easier.
This instruction is related to the pictures Fig. 41, Fig. 42.
1. Mount torque arm to the motor as described in chapter 7.4.1.
2. Make sure that the o-ring (6) is undamaged and lubricate it.
3. Check shaft/splines for burrs, to minimize the risk to damage the o-ring. Lubricate
shaft/splines with hydraulic fluid.
4. Remove the end cover (1) together with screws and washers.
5. Remove the plug G 1˝(2).
6. Mark spline tooth location on outside of motor bore to assist alignment during
installation.
7. Align the motor with the driven shaft.
8. Install the assembly tool by passing the tie rod through the centre of the motor,
and screw it into the driven shaft by using a wrench at the key grip at the end of
the assembly tool. Assemble the washer and then the nut tight to the
bearing retainer (3).
9. Rotate the cylinder block/motor to line up the splines with the drive shaft.
10. Pull the motor onto the shaft by turning the nut on the assembly tool.
11. Remove the assembly tool.
12. Remove the bearing retainer.
13. Mount the spacer included in the mounting kit (4) to the driven shaft.
Torque 450 Nm (332 lbf·ft).
14. Remount bearing retainer (3). Torque 136 Nm (100 lbf·ft).
15. Fill up with hydraulic oil to the G 1˝ thread. Axial clearance 10 mm [0,4 in] during
filling, see Fig. 42. Oil volume, see Table 16.
16. Fix the motor to the driven shaft by mounting the screw M20 (5). Torque 385 Nm
(284 lbf·ft).
17. Remount the end cover (1). Torque 80 Nm (59 lbf·ft).
