Which of the O.M.G. and Luk dual clutches, 11 or 12 inch, belongs behind your bellhousing is settled by the 357-page Landini Blizzard 65 parts catalog PDF (OEM reference 3540030M1) for this tractor. Exploded views break down the A4.236 engine, Orbitrol steering, draft control linkage and rear differential lock, with serial breaks like the 4/94 cab frame and A07033 transmission flagged so the part matches your build. Transmission fills the largest share of the book, from clutch linkage through every shuttle, creeper and overdrive reducer to the 540/750/1000 rpm PTO shaft; wiring diagrams trace the front harness and cab circuits. Fit the 7.5 amp fuse under part 3533928M91; front ballast weights come in at 36 kg. One wrong clutch disc means splitting the tractor twice. Bookmarks and a searchable text layer get you from part number to exploded view fast, so the first order is the right one and the tractor sees the field before the weather turns.
