Forward and Side Tilt Cylinder
Maintenance
Cylinder Disassembly
Removing tilt cylinder(s) from the
assembled Post Driver can cause an
unstable condition. To avoid
personal injury or death, make
sure the drive ram is stable and fully
supported by other means before removing
the tilt cylinders for service.
1. If removing cylinder(s) from the assembled
Post Driver, make sure the drive ram is fully
supported by other means, such as a
suitable overhead lifting device, before
disconnecting the tilt cylinders.
2. Disconnect the tilt cylinder hydraulic hoses
from the hydraulic control valve. Plug the
hoses and control valve fittings to prevent
dirt from entering the hydraulic system.
NOTE: Be prepared to collect any hydraulic
fluid that drains from the cylinder and hoses
into a suitable container.
3. Clean the outside of tilt cylinders (F3, F4).
Remove the tilt cylinders from the base
plate by removing the mounting pins.
4. Inspect the tilt cylinder mounting points.
Replace any worn or damaged
components.
