Clean the breather of droplegs regularly.
Dropleg Breathers
Breathers on top of the drop legs allow oil to
expand & contract without pressurising or
creating a vacuum in the drop leg housings.
Each dropleg breather must be cleaned at
regular service intervals.
Refer to the specification provided in the
'Maintenance Schedules' of this chapter.

Illustrated dropleg drive chains.
Dropleg Drive Chains
Drive chains of highest quality & designed for
long trouble free life are used in the droplegs.
Ensure proper dropleg care & maintenance is
followed to maximise chain & sprocket life.
Top drive chain uses Tsubaki 120 Super HT
chain & bottom drive chain uses Tsubaki 140
Super HT chain. Refer to the specification
provided in the 'Maintenance Schedules' of
this chapter.
Even the best chains will eventually stretch
over time & loosen. Maximum allowable chain
stretch is 1.5%. When this occurs the chains
must be replaced.
Chain service life is gauged by total stretch.
There is no tensioning mechanism. As chains
stretch beyond 1.5%, the chains will no longer
align correctly with the drive teeth. Therefore
proper replacement is mandatory to prevent
excessive wear of the drive spocket teeth.
Stretch gauges to check chains are available
from Goldacres.
Lubrication & Maintenance – Service
Replace dropleg drive chains when necessary.
Condition of Drop Chains
Drop chains do not have a specific service life.
Chain condition is determined by observing
metal particles in the oil & on the sump plug.
Larges numbers of metal particles larger than
1mm indicate the dropleg must be opened
for inspection. Possible chain & bearing failure
may be imminent and the dropleg should be
overhauled.
As preventative mainenance measure, chains
should be replaced whenever a dropleg is
opened.
