The Genie 108636GT Boom Cylinder Seal Kit is a genuine OEM seal kit built for the GTH-636 telehandler. Sourced directly from Genie, this kit carries the same dimensional and material specifications as the part seals installed at the factory, ensuring a correct, matched fit within the boom cylinder on the GTH-636. Cross-reference part number 108636GT against your machine's parts manual to confirm it matches your unit's serial range before ordering.
Key Features
- OEM-Grade Seal Material — Each seal in the kit meets Genie's original material and compression specifications, maintaining the integrity of the cylinder bore and rod surfaces it contacts.
- Complete Kit Format — Includes the seals required for a full boom cylinder reseal, so technicians have every component on hand to complete the job in a single service event.
- Exact Application Fit — Engineered specifically to the boom cylinder dimensions of the GTH-636; seals seat correctly without trimming, shimming, or adapting.
- Restored Cylinder Performance — Worn or damaged seals allow fluid bypass past the piston, causing the boom to drift or lose lifting capacity. Fresh OEM seals restore full cylinder extension force and holding ability.
- Operational Safety — A boom cylinder that holds position is fundamental to safe load handling on a telehandler. Replacing degraded seals with this genuine OEM kit helps ensure the boom responds predictably under load.
A boom cylinder seal kit contains the internal seals — including piston seals, rod seals, and wiper seals — that keep fluid contained within the cylinder while allowing smooth rod travel. Over time, seals harden, crack, or wear from heat and use, allowing fluid to bypass the piston or leak past the rod. When this happens, the boom may drift under load, respond sluggishly, or fail to hold a raised position. Replacing the full seal set at once restores proper cylinder function and prevents a partial repair from being repeated shortly after.
