What This Parts Catalog Gives You

This is not a generic overview or a condensed aftermarket guide. It is the complete parts catalog as published by John Deere for the 770D and 772D Motor Grader. Every major assembly is broken down into its component parts with exploded-view illustrations that show exactly how everything fits together. Each illustration is keyed to a parts list that provides the part number, part name, quantity required and serial number applicability.

The serial number information is particularly valuable. The catalog includes a dedicated section explaining where to find each serial number plate on the machine — the Product Identification Number below the operator’s platform on the left-hand side of the main frame, the engine serial number on the left-hand side of the cylinder block above the starting motor, the transmission serial number on the front of the transmission housing, the hydraulic pump serial number on the bottom of the pump, the front wheel drive hydraulic pump serial number, the HFWD motor serial numbers on each motor housing, and the differential serial number on the cover below the driveshaft input.

Throughout the parts listings, serial number break information is provided so you can confirm whether a given part fits your specific machine. When asterisks appear in place of a serial number, a serial number change was made and the details are in the remarks column. When X’s appear, the exact serial number was not available at time of publication. This level of detail prevents ordering the wrong part because of a mid-production change.

The catalog covers both the 770D and 772D models, with dedicated sections where the two machines differ. For example, the front axle and tie rod sections are separate for each model, as are the wheel lean cylinders, front transmission housings, hydraulic oil cooler hoses, and main hydraulic plumbing. The 772D benefits from additional front wheel drive (HFWD) coverage that is not present on the 770D, including the HFWD charge pump, engagement manifold, motor hydraulic lines, and motor solenoid and servo piston assemblies.

Engine coverage is extensive. The 8.1-liter John Deere engine is documented down to the component level: crankshaft, main bearings, connecting rods, pistons, cylinder liners, camshaft, valve train, cylinder head, exhaust manifold, turbocharger and oil lines, water pump, thermostat housing, oil cooler, oil pump, oil filter housing, fuel filter and lines, fuel injection system, starting motor, alternator mounting, fan drive, flywheel and flywheel housing. Gasket kits are also listed for both partial and complete engine rebuilds.

The transmission section is equally thorough, covering the front and rear transmission cases, gears, shafts, bearings, power shift clutch assemblies (first through sixth stage), transmission screen, output shaft, park brake, yoke, control valve, charge pump, filter, hoses, and oil cooler lines. Whether you are replacing a single bearing or rebuilding an entire clutch pack, the exploded views and parts lists give you the complete picture.

Hydraulic system coverage is split into the main hydraulic system (pump, manifold valve, control valve sections for blade tilt, articulation, circle sideshift, wheel lean, blade lift, blade sideshift, circle rotate, ripper, scarifier and auxiliary functions) and the steering system hydraulics (steering valve, front steering cylinder, articulation cylinder, wheel lean cylinders and all associated hoses). The blade impact system and saddle lock pin hydraulics are also included.

Beyond the major systems, the catalog covers the details that matter when you are doing a full machine refurbishment or just trying to replace a broken latch: cab and canopy frames, doors, windows (stationary, openable and sliding), wipers, interior panels, headliners, seats (both air and mechanical suspension), seat belts, cab steps, mirrors, radio and speakers, fire extinguisher, horn, back-up alarm, toolbox, sunvisors, SMV sign, and all the decals and labels.

The ground conditioning tool section covers front mounted scarifiers, rear rippers and scarifiers, their hydraulic cylinders, teeth, shanks, retainers and hoses. The grading device section covers moldboards (in various sizes including 12′, 13′ and 14′), cutting edges, overlay end bits, moldboard extensions, draft frame, blade tilt frame, saddle frame, circle frame, circle drive gearbox (with and without slip clutch), rotary manifold, circle drive motor, and the blade lift, slide and tilt cylinders.

Why This Matters

Ordering the wrong part costs time and money. A part that looks correct in a photo may have a different mounting pattern, a different port size, or a different internal configuration depending on the machine’s serial number. This parts catalog eliminates that guesswork. You see the exploded view, you find the item number, you look up the part number, and you confirm the serial number applicability. That is the correct workflow for anyone maintaining or repairing a 770D or 772D Motor Grader.

This catalog is equally useful for mechanics, parts managers, equipment owners and operators. If you are rebuilding a component, the exploded views show the order of assembly and the relationship between parts. If you are creating a parts order, the quantity column tells you exactly how many of each item you need. If you are trying to identify a part that has no visible number, the illustrations give you the context to match it to the correct assembly.
