_______5. Servicing and Maintenance
5.12 Changing a Rotor
Motor
This is one of the more complex tasks that
can be undertaken. The first stage is to
secure the unit in a safe manner allowing
access underneath. The next stage is to
depressurise the hydraulic system safely
as per previous instructions.
Then hydraulically disconnect both motors
to allow the top of the head assembly to
be unbolted and removed. Access to
unbolt the motor is underneath where the
rotors are attached. The assembly
process is very much as for a belt motor
with the added requirement of checking
the rubber cushioned drive on the top of
the rotor.
Once the motor has been fitted and all
bolts checked for torque the head should
be reassembled, again checking bolt
torques, in the reverse order; the
hydraulics reconnected and checked for
tightness and that they are clear from
trapping when the head is operated.
5.13 Changing a Rotor
Bearing
Follow the instructions for changing a rotor
motor except remove the rotors by lifting
them out and then access to the bearings
is now possible.
The procedure is then as for a belt bearing
except in this case a grease line is
attached to allow greasing to take place
once the unit has been reassembled.
Assembly is the reverse process taking
care to ensure that bolts are torqued up
and the hydraulic connections are tight
and clear of trapping.
5.14 Operator Support
If you have a problem, please contact your
dealer. They will endeavour to solve any
problems which may occur and provide
you with support at all times.
In order to enable your dealer to deal with
problems as quickly as possible, it helps if
you can provide them with the following
data.
Always state the:
• Customer Number
• Name and Address
• Machine Model
• Serial Number of Machine
• Date of Purchase and Operating Hours
• Type of Problem
5.15 Maintenance
Intervals
Apart from daily maintenance, the
maintenance intervals are based on the
number of operating hours and time data.
Keep a record of your operating hours to
ensure that the specified maintenance
intervals are adhered to as closely as
possible.
Never use a machine that is due for
maintenance. Ensure that all deficiencies
found during regular checks are remedied
immediately.
Avoid sharp-edged and
pointed parts (rotor blades,
etc.) when working on the
machine.
Place the machine on
suitable supports when
working underneath! Do not
work under a machine which
is not supported!
