Use the catalog section and application notes that match the tractor’s serial number and installed equipment. Exploded views, quantities, and replacement notes support parts identification and repair planning; this collection does not provide step-by-step overhaul or adjustment procedures.
Searchable Parts Tables and Catalog Bookmarks
Finding assemblies: Parts tables and figure headings are searchable. Embedded bookmarks open both figure indexes, the catalog sections, search instructions, and reference appendices; illustration callouts are generally not searchable. Small labels in the checked drawings are easier to read when enlarged. Five illustration pages display “ART NOT AVAILABLE,” affecting the later electrical-components overview and both accessories and dealer-stocking illustrations; their parts tables remain included.
One printable, 448-page PDF contains the two catalog sections listed above, plus one search-help page, 14 pages of abbreviations, two hardware-conversion pages, one additional front page, and two blank pages. All these additional pages are included in the total.
Drivetrain, SuperSteer, and Hydraulic Parts
The selected topics below cover the main assemblies; the catalog also lists operating decals and recommended dealer-stock parts.
-
Engine and fuel: Cylinder-block, cylinder-head, crankshaft, piston, injection-pump, and injector drawings, with gasket kits and model-specific component listings.
-
Transmission and PTO: Separate gear and hydrostatic assemblies, clutch components, PTO shafts, mid-PTO parts, and HST pedal and cruise-control linkages.
-
Axles and steering: FWD and SuperSteer assemblies, Sensitrak clutch parts, differential gears, steering cylinders, and serial-specific replacement components.
-
Hydraulic lift and remotes: Lift-cylinder and HPL control-valve breakdowns, pump and piping assemblies, rear remotes, and Prince loader-control valve drawings.
-
Electrical equipment: Harness listings, relay and fuse locations, safety switches, glow-plug controls, and exploded alternator and starter-motor views.
-
Chassis and operator equipment: Parking-brake components, standard and deluxe hitch linkages, seat assemblies, hood panels, and rigid or foldable ROPS parts.
Suited to mechanics and experienced owners who can match assembly callouts and application notes to the tractor’s installed equipment.
HST, Gear Transmission, and PTO Assemblies
The Deluxe HST Assembly drawing separates the rotating group, pump and motor valve plates, charge pump, and port-block components. Its parts tables distinguish components used with different HST assemblies, so a similar-looking housing alone is not enough to select internal parts.
Gear-transmission drawings identify input shafts, countershafts, shifters, and clutch components. PTO listings distinguish rear countershafts with a one-way clutch from versions without one; mid-PTO pages identify the associated shaft, linkage, shield, and safety-switch parts.
SuperSteer, Steering Cylinders, and Hitch Linkages
The Front Axle, Differential & Sensitrak Clutch drawing shows the SuperSteer driveline arrangement. Steering-cylinder tables distinguish original assemblies from replacements and identify the corresponding guide and seal kits.
The Power Steering Case Assembly section provides internal breakdowns for the named original steering units. Several replacement units are explicitly listed without a component breakdown. Standard and deluxe three-point hitch illustrations also change by serial application.
Engine Parts and Replacement Notes
Cylinder-block tables distinguish bare, short-block, and long-block entries and identify components excluded from the long block. Crankshaft and piston tables pair replacement piston kits with their corresponding ring sets.
The cylinder-head listing warns that press-fitting a replacement prechamber can crack the head, explaining why the prechamber is not serviced separately. Injection Pump and Fuel Injector Assembly drawings identify internal components, while radiator and air-cleaner tables separate replacement configurations.
Hydraulic Valves and Electrical Layouts
Prince HC-V-AB10 and HC-V-AE35 valve listings distinguish joystick hardware, detent kits, relief cartridges, and seal components. The Two-Spool Remote Control Valve Assembly drawing includes sectional views showing the relationship between these parts.
Relay, Diode & Fuse Locations drawings identify electrical hardware and its position. These are component-location illustrations, not circuit schematics or electrical troubleshooting charts.
Always relieve hydraulic pressure and properly support the chassis before servicing heavy driveline components.
Selected Steering-Seal Dimensions and Injection-Pump Shims
The original power-steering case breakdown lists an O-ring with a 1.859-inch inside diameter and 0.139-inch thickness. These dimensions describe a cataloged replacement component, not a steering-system test limit.
The injection-pump parts table lists a shim set containing one each of 0.2, 0.3, 0.4, and 0.5 mm thicknesses. It identifies the available parts; it does not provide a pump-timing adjustment procedure.
