NOTE: DO NOT remove the piston from the ram. The O-ring between the ram and the piston is not service-
able.
27. Inspect the cylinder and rod before proceeding:
27a. Inspect the shaft and piston to confirm that the cylinder is rebuildable.
NOTE: A bend or surface damage on the rod will make the cylinder unfeasible to rebuild.
27b. Inspect the cylinder bore for deformations and surface damage.
27c. Inspect the hydraulic fittings on the cylinder for damage.
27d. Inspect the cylinder for cracks around the fittings and welds. Magnaflux if in doubt.

22. Clean the paint from the inside edge of the cylinder.
See Figure 5.15.
NOTE: Paint on the inside edge of the cylinder can catch
the back-up ring, pulling it out of the grove and
wedging between the rod guide and the cylinder
wall.
23. Pull the ram out of the cylinder.
Do not use compressed air to force
the piston out of the log splitter bore.
Compressed air may eject the piston
with dangerous force.
NOTE: The piston will catch the rod guide and pull it out
with the ram.
NOTE: The piston and the rod guide may separate from
the cylinder quickly. Be prepared to support the
weight of the rod and the guide.
NOTE: Be careful not to mar the chromed surface of the
piston rod.
NOTE: If the rod guide will not come out of the cylinder:
• Push the ram all the way in.
• Attach a puller to the rod guide. See Figure 5.16.
• Gently pull the rod guide out.
NOTE: If a puller was needed to pull the rod guide out, the
outer O-ring and the back-up ring of the rod guide
are most likely destroyed.
24. Slide the rod guide to the end of the ram, opposite
the piston.
25. Support the ram in a vise with padded jaws.
26. Remove the rod guide.
NOTE: If there is paint on the end of the rod, it must be
removed before the rod guide can be removed.
