6.6.2 Demounting the type HYD shrink disk
• Remove the protective cover.
• Remove screw plugs from the "Clamp" and "Release" connections.
Collect any hydraulic fluid that may run out!
• Connect the oil pressure pump to the connection marked "Clamp".
• Increase the oil pressure (max. 450 bar) until the lock nut can be loosened by hand.
• Relieve pressure and attach pump to connection marked "Release".
• While the oil pressure is increasing, the outer ring will slip off the cone of the inner ring. The connection
is disengaged again.
• Leave hydraulic fluid in the released shrink disk and firmly reseal the "Clamp" and "Release"
connections with the screw plugs.
• Remove the machine shaft or slide the gear unit off the machine shaft. Rust deposits which may have
formed on the shaft must be removed before performing this operation.
• Pull the shrink disk off the hollow shaft.
6.6.2.1 Cleaning and greasing the type HYD shrink disk
Released shrink disks do not have to be disassembled and regreased before being reclamped.
The shrink disk should only be disassembled and cleaned if it is dirty.
Following cleaning, only the inner sliding surfaces of the shrink disk should be
regreased.
Use a solid lubricant with a high MoS
2
based molybdenum disulphide content and with a coefficient of
friction of μ = 0.04 according to the following table.

6.7 Installation of the torque arm
For all shaft-mounting gear units, the reaction torque corresponding to the torque of the
machine and acting in an opposite direction on the housing must be absorbed.
6.8 Gear unit with motordriven oil pump
• Wire the motor electrically.
• Wire the double changeover filter electrically.
• Wire the pressure monitor electrically.
• Wire the volumeflow meter electrically.
If a terminal box is delivered attached to the unit, the electrical leads to the devices are already wired up
in the terminal box.
