Inner Shaft Disassembly
Wrap a rag around the upper post below the seal head.
Use a 23 mm, or adjustable, open end wrench to unthread the internal
seal head three full turns. Do not remove the seal head.
Wrap a rag around and over the internal seal head.
Slowly unthread the seal head by hand while holding the rag over the
seal head.
A small amount of air pressure may be released when the seal head is
completely unthreaded. Do not remove the rag from the seal head until
the seal head is completely unthreaded.
Wrap the rag around the upper post to absorb hydraulic fluid and
carefully remove the seal head and inner shaft assembly from the
upper post.
⚠
WARNING - EYE HAZARD
In the event there is any remaining air pressure inside the upper post
assembly, the rag will prevent the internal seal head from dislodging
from the upper post during removal.
Remove the upper post from the vise and pour the hydraulic fluid into
an oil pan or container.
Set the upper post aside.
