The Genie 80947GT is a genuine OEM Donyang Cylinder Seal Kit built for Genie GR-series Runabout vertical mast lifts, including the GR-8, GR-12, and GR-15. As a direct OEM replacement, this seal kit is manufactured to the same specifications as the original component, ensuring a proper fit with the Donyang cylinder (cross-reference 57997) used on these machines. Verify part number 80947GT against your machine's parts manual before ordering to confirm it is the correct kit for your unit.
Key Features
- Genuine OEM Sealing Materials — Manufactured to Genie OEM standards, this kit includes seals sized and compounded to match the original Donyang cylinder specifications, maintaining the dimensional conformity the cylinder requires.
- Direct Cylinder Replacement Kit — Engineered to replace the original seal set in the Donyang cylinder assembly (57997) without modification, keeping the rebuild process straightforward.
- GR-Series Fitment — Confirmed fit for GR-8, GR-12, and GR-15 Runabout vertical mast lifts, covering the cylinder configuration shared across these models.
- Restores Cylinder Function — Worn or degraded seals allow fluid to bypass within the cylinder, causing the mast to lose lift capacity or drift. Fresh seals restore the cylinder's ability to hold position and operate smoothly under load.
- Operational Safety — On a personnel lift, a cylinder that cannot hold its rated load is a safety concern. Replacing seals with the correct OEM kit helps ensure the lift performs as designed and holds platform position reliably.
A cylinder seal kit contains the full set of seals, O-rings, and wipers needed to rebuild a hydraulic cylinder to its original operating condition. Over time, seals wear, harden, or become damaged, allowing fluid to bypass inside the cylinder — this causes the mast to drift downward, respond sluggishly, or fail to hold a load. Replacing the complete seal set restores the cylinder's internal integrity. Using the correct OEM kit for the specific cylinder model — in this case the Donyang cylinder on GR-series Runabout lifts — ensures each seal is the right material, size, and profile for the bore and rod dimensions it must seat against.
