6 Maintenance
- After 3 hours
- After 10 hours or 1 day*
- After 40 hours or 4 days*
* If no additional torque is added when retightening the pins, the installation is successful.
If the expander sleeves have not bedded in after one week's operation, contact your
dealer.
6.3.2.2. Removal
1. Unscrew the fasteners on both sides and remove any washers.
2. Tap the shaft body until the sleeve on the impact side releases. Use a pipe as a drift
between the hammer and the shaft to prevent damage to the threads. Make sure the pipe
is not touching the sleeve, and that its internal diameter is slightly larger than the thread.
3. Remove the sleeves and the shaft.
6.3.2.3. Before installation
Do not try to install the expander pins with the wrong sleeve size or the pins will not work.
- Make sure there is no structural damage present (e.g. broken or severely deformed
lugs) that could affect attachment point alignment. If damage is present, the system
may not function as expected.
- Repair any damage.
- Check maximum and minimum wear in the attachment lug hole to make sure you
have the correct size expander sleeve for each side of the shaft. Each sleeve expands
max 0.08 inches. If maximum wear exceeds this value, contact your dealer to order a
suitable oversize sleeve.
- Visually inspect the attachment lug hole. Remove
any sharp edges and other unevenness. If the
difference between maximum and minimum wear
is greater than 0.06 inches, the hole must be
drilled out or ground so that ovality is less than
0.06 inches.
MAX - MIN < 0.06 inches
In the case of extreme wear, contact your dealer.

6.3.2.4. Installation
1. Grease the shaft and expander sleeves with bearing grease to make installation easier.
Start by installing the shaft body, followed by the sleeves, washers and fasteners. Take
care not to damage the threads or the conical parts in the expander pins.
2. Center
(normal)
or position
(inset versions)
the shaft in the correct position and then
tighten the fasteners by hand.
