XCMG Spare Parts SEAL KIT JACK DOWN TB69585 910908766

XCMG spare part TB69585 is a genuine seal kit for the jack down cylinder. It’s made to restore hydraulic lifting and lowering functions on specific XCMG truck-mounted cranes and heavy equipment.

This kit directly replaces OEM number 910908766. You get all the O-rings, backup rings, and dust seals needed for one complete cylinder reseal. No cutting or improvising required.

We see these seals fail mostly from dried-out rubber or contaminated oil. When your jack down drifts or won’t hold position, this kit brings back positive lock and smooth movement.

Each seal matches XCMG’s original shore hardness and groove dimensions. Aftermarket universal kits often leak here because they ignore the backup ring thickness. This one fits right the first time.

Keep a kit on the service truck. When that jack down cylinder starts sweating oil, you’ve got the exact TB69585 seals ready. Job takes about an hour with basic hand tools.
