John Deere 1270G Wheeled Harvester Parts Catalog PC13923

This is the complete John Deere parts catalog for the 1270G Wheeled Harvester configured as 8W Tier 2 on the FT4 Platform with Rotating and Levelling Cabin, Gen II, Grey. Published as PC13923 in January 2022 in English, it is the parts reference used to identify and order components for machines from PIN 1WJ1270G_C004999- onward. Every section is illustrated with exploded views keyed to part numbers, quantities and serial-number applicability notes, so you can match the exact part fitted to your machine rather than guessing from a description. Engine coverage inside is for the 6090HTJ24 diesel. The catalog spans 1336 pages and covers all major machine groups: wheels and tires, axles and differentials, transmission, engine, cooling and starting aids, fuel system, steering, service brakes, electrical systems, operator station, hydraulics, boom and crane assemblies, and grapple and rotator joints.

As a whole, this parts catalog gives a technician the illustrated component breakdown for every major assembly on the 1270G harvester. Each exploded drawing is keyed to a parts table listing the John Deere part number, the part name, the required quantity and any serial number range that restricts fitment. That structure is what makes a parts catalog different from a service manual — it does not walk through repair procedures or torque sequences, but it does let you identify the precise component, subcomponent, seal kit, fitting, hose, bearing or fastener that sits in a given position on the machine, then match it to the serial-number break so you order the correct item for the build of your harvester. Sections that involve wear parts, seal kits and rubber components are broken down to individual pieces, which is especially useful when only a seal, O-ring or bearing needs replacing and the assembly does not.

Which Machines This Covers

This catalog is specific to the 1270G Wheeled Harvester in the 8W Tier 2 configuration on the FT4 Platform, with the rotating and levelling cabin, Gen II, in grey. The engine group inside is dedicated to the 6090HTJ24 diesel. Serial-number applicability is printed against individual part lines, so a part that only fits machines from a given serial onward — or only up to a given serial — is called out in the Remarks column rather than being left to guesswork. The catalog was published in January 2022 and covers machines manufactured from 2020 onward, beginning at PIN 1WJ1270G_C004999-.

IMAGES PREVIEW

Why the Serial Number and Part Number Detail Matters

Harvester components change through a production run, sometimes at the assembly level and sometimes only at the level of a fitting, hose length, bracket or seal. Ordering from a generic description frequently results in a part that bolts up to the wrong serial range or supersedes to a different number. This catalog resolves that by pairing exploded-view keys with the exact part number and a serial range where applicable, and by listing remanufactured options, substitute numbers and no-longer-available items where John Deere has updated them. Assemblies that include a seal kit or a repair kit are noted so the kit is not missed on the order.

How Sections Are Organised

The front of the catalog includes a sectional pictorial index for the engine, followed by the illustrated groups. Each group is composed of an illustration page with numbered callouts and a facing table listing the part number, part name, quantity and remarks. Group numbering follows John Deere’s standard parts catalog hierarchy — the first two digits indicate the major system, and the last two indicate the subsystem. The alphabetical index at the back lets you start from a part name or topic and jump directly to the illustration and table page where it appears.

Buying the Correct Part with This Catalog

Using the John Deere 1270G Wheeled Harvester parts catalog PC13923 lets you look up the exact part for your harvester by group, by illustration callout or by alphabetical index, confirm the serial-number applicability and order with confidence. It supports the day-to-day parts work on the machine: locating a failed bearing or seal in an axle or final drive, finding the correct hose or fitting in the hydraulic or steering lines, identifying a sensor or relay in the electrical system, matching a seat or cab component, and confirming the right nozzle, turbocharger or fuel system part for the 6090HTJ24 engine. It also helps when the part is no longer available in its original form, because the catalog often shows the substitute or reman number in the remarks. Getting the right part the first time reduces machine downtime, avoids return shipping on incorrect orders and keeps the harvester working in the stand.

The catalog is supplied as an instant-download PDF, so there is no shipping and no wait. It opens on a workshop laptop, tablet or phone, and any page or parts table can be printed and taken to the machine or the parts counter. Search, zoom and page navigation let you move quickly between the illustration and the parts table while you are working. The complete 1336-page catalog is delivered in a single file, ready to use as soon as the order is placed.
