TRS Pull Down
Forks
The pull down forks are scheduled in for inspection, cleaning and greasing on
a six monthly basis.
Only a small amount of grease needs to be applied to the grooved area that
engages the pull down cylinder cap and to an equivalent area at the base of the
fork.
Once applied, the system should be cycled to allow the dynamic distribution of
the grease and at the end of the cycle, any excess (grease that has spread away
from the applied areas) should be removed.
Light grease p/n 120011 should be used.

SUMMARY OF THE PROGRAMME
28.6 Technical Reference Manual Chapter Issue 5, Aug 14
SUMMARY OF THE PROGRAMME
The PM Plan
Daily This maintenance schedule is a recommended programme which should be
carried out on a daily basis. Tasks are generally limited to surface cleaning and
minor inspections and should take no more than fifteen minutes to complete.
Monthly This maintenance schedule is a recommended programme which should be
carried out on a month by month basis. It comprises two modules that are
designed to take approximately 2 hours each to complete.
In the first module, SPC Alignment, Machine Cycle Count, Software Checks and
a standard Monthly Maintenance Check make up the elements.
NOTE
SPC Alignment is included in the QC Calc Software package which is an
optional measurement tool.
The second element comprises the Monthly Hardware Check, each month one
or more hardware modules are scheduled for maintenance. Over a twelve
month period all machine modules are checked and serviced at least once.
Each monthly schedule, January through to December is the same no matter
where the machine resides. ASM service engineers already have maintenance
history on which modules have been serviced and those that are in need of
service. If an error occurs the precise service history is known and this could
prove useful in tracking a fault condition.
