The alphabetical index at the front of the catalog lists every part name with its grid location and page number, so you can jump straight to the correct illustration. The numerical index at the back lists every part number with its grid and key number, making it straightforward to confirm a part number or find where a component is used. This is the reference you want when you need to identify a part on the machine, verify a part number before ordering, or understand how an assembly goes together.

Serial Number Information for Your Machine

John Deere built the 640G-II and 648G-II with five serial numbers on each machine: one for the product identification plate, one for the cab, one for the engine, one for the hydraulic pump, and one for the winch. The product identification number plate is located on the left upper rear corner of the engine frame (640G-II) or the upper rear corner of the engine frame (648G-II). The engine serial number plate is on the right-hand side of the cylinder block behind the engine oil filter. The hydraulic pump serial number plate is on the right-hand side of the hydraulic pump. The winch serial number is on the upper front of the winch housing. The catalog uses the machine serial number range 565685-576602 to identify which parts apply to which machines, and many sections include further serial number breaks so you can match the exact configuration of your skidder.

Engine and Component Identification

The engine serial number plate identifies the engine manufacturer, number of cylinders and liters, fuel type or special condition, engine serial number, and the engine application and factory user. The 640G-II and 648G-II use the John Deere 6068 turbocharged diesel engine (6.8 liter). Engine serial plates appear in three variants depending on where the engine was built: Dubuque Option, Saran Option, and Torreon Option. The axle serial number breakdown identifies the manufacturing unit, component identification, configuration identity, serial number, master machine code, family code, primary input rotation and axle travel, spiral bevel reduction, input yoke size and style, flange to flange width, input housing and auxiliary brake, mounting type, brake type, differential type, differential case, final drive reduction, trim, and miscellaneous parts. This level of detail means you can identify exactly which axle variant your machine carries and order the correct internal components.

What This Parts Catalog Enables

With this John Deere 640G-II and 648G-II Parts Catalog PC2669, you can look up any part on the machine by assembly, confirm the part number before contacting your dealer, and see exactly how components fit together. The exploded illustrations make it possible to identify a part even when you do not know its name, and the complete goods listings (shown in bold face type) tell you when an item must be ordered as a complete assembly rather than as individual components. For anyone maintaining, repairing, or restoring a 640G-II cable skidder or 648G-II grapple skidder, this catalog is the parts reference that keeps the machine running with the correct components.

Why Correct Part Numbers Matter

Skidders work hard in demanding conditions, and using the wrong part can lead to premature failure, damage to mating components, or unsafe operation. This catalog removes the guesswork by giving you the exact part numbers John Deere specified for each serial number range. When you are ordering a hydraulic hose, a seal kit, a clutch plate, or a final drive gear, having the right number the first time saves downtime and avoids return shipping. The serial number breaks throughout the catalog are especially important because John Deere made running changes during production, and a part that fits an early machine may not fit a later one.
