John Deere 3640 Overview
Built from 1984 through 1987, the John Deere 3640 is listed with a 359 cu in (5.9 L) direct-injection diesel rated at 117 gross hp. The published drivetrain is a Power Synchron partial power-shift with 16 forward and 8 reverse gears, but the serial number and installed equipment still decide which manual and parts information belongs to a particular tractor.
Published information also lists independent 540/1000 PTO, closed-center constant-pressure hydraulics, a Category II/III rear hitch, and a 49.2 gal fuel tank. The figures below are reference data, not instructions to service or fit an individual 3640 without configuration checks.
John Deere's official manual portal and the model-specific technical-manual and parts-catalog references are practical starting points for documentation. The matching complete manual remains the authority for procedures, settings, and fitment.

Parts Checks Before Ordering
Start with the serial number, then identify the installed Power Synchron equipment, PTO, hydraulic valves and remotes, hitch, wheel equipment, ballast, and any front-drive configuration. The model designation alone is not a complete parts match.
The linked 3640 parts-manual listing is a route to catalog material, not proof of a part number or fitment. Confirm all numbers and coverage in matching John Deere documentation before ordering.
