Drift, fluid leaks, or performance changes can indicate a Cilindro hidráulico needs repacking. The process is simple and quick. Step-by-step instructions for repacking a hydraulic cylinder.
Workspace prep
Clean your workspace before disassembling and repacking the hydraulic cylinder to avoid contamination. We recommend opening your hydraulic cylinder repacking kit when ready to instal new seals. Repacking a hydraulic cylinder requires:
- Hydropacking kit (search by equipment model to find a kit compatible with your cylinder)
- Hydraulic oil replacement
- Piston rod wrench
- Limpio, lint-free cloths to wipe parts and spills
- Large container for old hydraulic oil
SAVE! If you plan to use equipment for lifting or supporting weight, use jacks or blocks. This prevents injury and damage to expensive piston assemblies.
Hydraulic Cylinder Repacking
TIP: During disassembly, note the location of each component to ensure proper reassembly. Check for fluid leaks and corrosion, daño, or wear on cylinder components and mounts.
Slow and careful work will yield a leak-free hydraulic cylinder.
- Drain the cylinder.
- Disconnect the cylinder’s hydraulic lines.
- Removing lines lets the cylinder’s remaining pressure escape.
- Ensure the hydraulic cylinder won’t fall.
- Once everything is stable, remove the cylinder’s pin.
- Discard the cylinder gland.
- This varies by manufacturer. Some glands are bolted, and others require a special tool inserted into small holes to turn. A small tap or hammer bump may loosen the gland. Once loose, it should unscrew from the piston rod.
- Remove cylinder piston rod.
- Keep the piston rod from touching other metal or falling. Corre el riesgo de contaminar o dañar el vástago del pistón.. Al retirar la varilla, Tenga cuidado de no dañar las roscas del cilindro.. Estas piezas son caras de reemplazar..
- Diferentes métodos sujetan la varilla al pistón..
- Un pistón se puede unir a una varilla roscada directamente o con una tuerca o tuerca y perno.. Cuando la varilla está libre del cilindro., quitar el pistón. Mantenga las piezas en orden y tome una foto si es necesario.
- Reemplace los sellos del pistón y del casquillo uno por uno.
- Esto reduce la confusión y mejora la colocación.. Utilice el sello correcto. Los sellos delgados pueden dañarse si no se instalan de manera uniforme. Antes de reemplazar una pieza, limpiar cada ranura.
- Vuelva a montar el pistón y la varilla.
- Reemplace los pernos del vástago del pistón con adhesivo bloqueador de roscas. Antes de volver a montar, lubricar y limpiar todas las piezas.
- Vuelva a instalar la glándula.
- Nunca bloquee las roscas del prensaestopas.
- Replace all hydraulic lines and test seals for leaks.
Repacking hydraulic cylinders as part of annual maintenance extends their life. This repacking procedure should work for most welded rod cylinders. If you have questions, consult a professional.
