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
1.
Mount torque arm to the motor with screws supplied as described in chapter
7.4.1: Fitting the torque arm on the motor.
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 cover (1) together with screws and washers.
5.
Mark spline tooth location on outside of motor bore to assist alignment during
installation. Install the spline align assembly tool to align the motor spline
with the driven shaft according to section
: Mount the spline alignment tool page
6.
Align the motor with the driven shaft.
7.
Install the assembly tool by pass 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 holder (3).
8.
Use a bar to rotate the cylinder block to fit the teeth with the drive shaft.
9.
Pull the motor onto the shaft by turning the nut on the assembly tool.
10.
Remove the assembly tool and the spline alignment
tool.
11.
Fix the motor to the driven shaft by using the mounting kit (4): Mount the
spline alignment tool again. Torque the spacer to 1840 Nm (1357 lbf·ft).
12.
Remount bearing holder (3). Torque 80 Nm (59 lbf·ft).
13.
Fill up with hydraulic oil to the G 1¼ thread. Axial clearance 10 mm [0,4 in]
during filling, see
. Oil volume, see
Mount the screw M30 (5).
Torque 1840 Nm (1357 lbf·ft).
Alternatively: Mount the screw M30 (5). Torque 1840 Nm (1357 lbf ft.) Remove
one of the two G ¼ plug (7) on the bearing holder and G ¼ plug (8) on
shaft side seal retainer and pump in oil until oil is coming out from the G ¼
connection on shaft side seal retainer, see
. Torque the G ¼ plugs. Torque
30 Nm (22 lbf ft.)
14.
Remount the cover (1). Torque 200 Nm (148 lbf·ft).
