Genie 111552.0001.S is a Genie OEM replacement bevel gear (30t, hoist) for commercial door operators. Constructed from Hardened steel (typical bevel gear construction for commercial hoist drivetrains), it is designed for durability in continuous-duty commercial installations. Installation: Keyed onto hoist mechanism shaft; secured by set screw or retaining hardware and meshes with corresponding bevel pinion. Compatible with: Genie HXH Commercial Hoist Operator (hoist mechanism), Genie HX Commercial Hoist Operator (hoist mechanism).
A: Despite having the same 30-tooth count, 111552.0001.S (hoist) and 111553.0001.S (reducer) have different bore diameters, keyway dimensions, or mating gear profiles to suit their respective shaft and load conditions. They are NOT interchangeable.
A: The 30-tooth count determines the bevel gear ratio in combination with its mating pinion. The tooth count must match the OEM specification to maintain correct drum speed, door travel rate, and limit switch calibration.
A: This gear is installed in the hoist mechanism (drum drive side) of the operator. The 111553.0001.S bevel gear of the same tooth count is installed in the gear reducer stage. Always identify the installation location before ordering.
A: Inspect for chipped or broken teeth, pitting on tooth flanks, excessive backlash when meshed with its pinion, and abnormal noise during operator cycling. Any cracked tooth requires immediate replacement.
A: Use only the lubricant specified in the Genie HXH/HX service manual. Bevel gear sets require adequate lubrication at tooth contact faces to prevent scoring; check lubricant condition at each scheduled maintenance interval.
