Visually inspect for any wear or damage and ensure that all bolts, clevis’ and other fasteners are fully
secure. Ensure that clevis pin threads are not visible on damper rods. Check to ensure that there is
no sign of any fluid leaking onto the damper rods.
Check the condition of the springs and test the operation of the springs. If the springs show
excessive corrosion or have started to yield then they should be changed out.
The springs can be susceptible to yielding over time. The following check is recommended to identify
whether the springs are fit for purpose:
In-situ check The top of the sliding sleeve should rest against the compression stop. If a
space exists between the top of the sliding sleeve and the compression
stops greater than 10mm, then the Springs should be replaced.
The Recoil Dampers need to be checked too. Ensure that the damper rod-end threads are not visible
below the clevis pin eye. Ensure that there is no sign of any fluid leaking onto the damper rods. The
Recoil Dampers should also be disconnected at one end so that their operation can be checked and
to check for any bowing of the damper rods.
Check the spring compression plate for any signs of deformation.
Examine the feet to ensure that they are in good condition and that they are properly secured to the
capsule. Do not go underneath an active lift.
Notes:
i.
Measure height of foot and replace if under 100 mm in height
ii.
Small (20 mm in length) cuts are acceptable but feet should be replaced when
damage larger than 20mm is present.
