With a weeping tilt cylinder on the bench and the parts counter waiting for a number, you'll want the Gehl 552, 553, Dynalift parts catalog PDF open: 180 pages, publication 908459, covering both telescopic boom forklifts from cab to carriage. Hydraulic component breakdowns make up the largest share of the book, with exploded views of the pump, main valve, joysticks, frame level valve, and every lift, tilt, slave, and boom extend cylinder. Each model gets its own boom pages, so the two-section 552 and the three-section 553 never get confused. The axle pages break the outer ends, differential housing, and brakes down part by part. Confirm L99927 is the 350 PSI relief valve before ordering. A wrong seal kit costs you the freight, a second teardown, and another week with the lift parked. Bookmarks and the numerical index take you from a part number to its exploded view, and any callout is one search away.
