Description

John Deere 770C, 770CH and 772CH Series II Graders Parts Catalog PC2906

This is the John Deere 770C 770CH 772CH Series II Graders Parts Catalog PC2906 – the full illustrated parts book for the 770C, 770CH and 772CH Series II motor graders within serial number range 589369 through 596105. Every assembly in the book is broken down into exploded views with keyed callouts, and the matching part list gives the part name, quantity, serial number application and remarks for each key number. That combination is what lets you identify the right component on the machine and then confirm the exact number to order.

Because this is an illustrated parts catalog rather than a service manual, its value is in identification rather than adjustment. Every system on the 770C, 770CH and 772CH Series II is drawn in exploded form with key numbers that tie directly to the parts list on the facing page. Where a component was changed during production, the serial number column tells you which side of the break your machine falls on, and the remarks column flags substitutions, whole-good assemblies and no-longer-available numbers with the replacement to order instead. The numerical index at the back of the file runs the entire part number list alphabetically so a known number can be traced straight to its grid and page.

What This Parts Catalog Lets You Do

With the PC2906 parts catalog open you can build an accurate parts order for almost any job on the machine. That includes driveline and axle work such as final drive, tandem pivot, differential case and housing, differential lock plumbing, and the HFWD hub and motor assemblies. It covers the transmission case, the first through sixth stage clutch and gear assemblies, the transmission charge pump, accumulator and filter, and the full control valve stack. Engine coverage runs from the cylinder block and short block through the pistons, liners, cylinder head, injection system, turbocharger, oil cooler and gasket kits. Around the machine you can look up the main hydraulic pump, every control valve section, the main relief valve, the filter head and the reservoir plumbing, plus all the grading cylinders, the rotary manifold, circle drive gearbox and motor, and the draft frame, circle frame and saddle assemblies.

Parts identification is where a catalog like this earns its keep. Ordering a cylinder seal kit or a replacement hose by eye on a machine that has been through several serial number updates is how wrong parts get shipped. Here the serial number column, the remarks and the exploded callouts settle those questions before the order goes in. The five-hole end bit moldboards and cutting edges, the overlay end bits, the blade lift, side shift, tilt and slide cylinders, and the ripper and scarifier shanks and teeth are all itemised, as are the smaller consumables that are easy to get wrong, such as O-rings, fittings, clamps, fasteners and seals.

The electrical and operator station sections are just as detailed. Battery cables and grounding straps, alternator and drive belt, front and rear work lights, stop, turn and tail lights with the incandescent-to-LED changeover, dome light, cab roof harness, platform harnesses, engine wiring harness, sensor and switch listings, monitor and warning buzzer are all present. Cab and enclosure coverage includes the ROPS, cab frame, doors, latches, window panes, wiper motors and arms, wiper blades, washer pumps and tanks, the air suspension and mechanical suspension seats, the cab heater, the air conditioning module, blower assembly, condenser, receiver-dryer and all the refrigerant hoses and O-rings.
