Can a Welded Body Cylinder Be Repaired, or Does It Need to Be Replaced?

In most cases, it can be repaired. Machining into the barrel to access the seals and internals is a more involved process than a tie-rod rebuild, but it's usually still more cost-effective than full replacement unless the barrel or rod itself is too damaged to restore safely.

Does Machining Into a Welded Body Cylinder Weaken It?

Not when it's done correctly. Our technicians machine and reseal to OEM specifications so the cylinder holds pressure the same way it did before the repair, rather than leaving a weak point at the access area.

Why Don't Welded Body Cylinders Have Tie Rods?

Welding the end caps directly to the barrel removes the need for external tie rods, which allows for a more compact cylinder that can handle higher pressure in tight-clearance applications like mobile equipment and dump bodies.

Is a Welded Body Cylinder More Expensive to Repair Than a Tie-Rod Cylinder?

Often, yes, since accessing the internals requires machining rather than simply unbolting the end caps. The exact cost still depends on the extent of the damage found during inspection.

Precision Repair for Welded Body Cylinders

Unlike a tie-rod cylinder, a welded body cylinder has its end caps welded directly to the barrel as a single sealed unit, which makes it more compact and better suited to handling high pressure without external tie rods getting in the way. That construction is common on mobile equipment, dump bodies, and OEM applications where space is tight and durability matters more than easy field access. The tradeoff is that a welded body can't simply be unbolted for service; accessing worn seals or a damaged rod means machining through the existing joint, which takes more specialized equipment than a standard tie-rod rebuild. Miller Hydraulic has repaired welded body cylinders since 1991 and has the machining capability most shops don't keep in-house.

Welded Body Cylinder Machining & Repair

Because a welded body cylinder doesn't come apart the way a bolted or tie-rod cylinder does, our technicians machine into the barrel to reach the internals, replace the worn seals, rod, or bore surface, then reseal and re-close the unit so it holds pressure exactly as it did new. That process demands more precision than a standard rebuild, since a poor reseal on a welded body cylinder can't be caught and re-tightened the way a loose tie rod can. We treat every welded body job individually, machining only what's needed to reach the damage rather than opening up more of the cylinder than the repair requires.

Welded Body Cylinder Repair & Emergency Service

When a welded body cylinder starts leaking or losing pressure, the fix usually comes down to machining and resealing rather than a full replacement. Contact Miller Hydraulic for a free estimate and 24/7 emergency service for urgent situations.
