Which part fits which machine in the Gehl HL series is settled by this 64-page Gehl HL4500 parts catalog PDF, Form No. 902578, which covers four skid steer loader variants in one book. Each engine gets its own exploded views: the air-cooled Wisconsin in the HL4300, Ford gasoline in the HL4500, Ford LP gas in the HL4700 and the Perkins diesel in the HL4600. Hydraulics take up a large share of the pages, breaking down both piston pumps, the gear pump and the Columbus and Lantex lift and tilt cylinders so you can confirm which cylinder brand your loader carries before you order. Trace the drive chain and axle sprocket on the axle and drive pages, then run any part number backward through the numerical index to find its assembly. A guessed part number parks the loader for days. Bookmarks in this text-searchable file reach the load arms or the T-bar controls in a click or two.
