Massey Ferguson 6400 Series Tractor Workshop Service Manual – Introduction, Specifications & Splitting Procedures

This Massey Ferguson 6400 Series Tractor Workshop Service Manual extract brings together the reference material every technician needs before lifting a spanner on a 6400 series machine: the full general specifications for each model in the range, ground speed tables, dimension and attachment point drawings, fluid capacities, conversion tables, sealing compound guidance, tightening torque charts and – most importantly – the complete step-by-step splitting procedures for separating the front frame, engine, gearbox and centre housing.

Issued as AGCO document number 3378405M4, this extract covers the entire Massey Ferguson 6400 family, from the 90 hp 6445 up to the 215 hp 6499, in both Dynashift and Dyna-6 transmission variants. Whether you are servicing a Perkins-powered 4-cylinder 6460 or a SISU-powered 6-cylinder 6499, the splitting sequences and specification data here apply directly to the machine in front of you.

Chapters Covered

This extract is built from two primary sections of the wider 6400 series workshop service manual: chapter 01 (Introduction – Specifications) and chapter 02 (Splitting the tractor). The coverage is detailed below.

01 – Introduction – Specifications

• 1A10 – Using the manual – structure, page numbering, references, amendments, service tools, repairs and replacements
• 1B10 – General specifications – model-by-model specs for the full range:
  • 6445 Dynashift / Dyna-6
  • 6455 Dynashift / Dyna-6
  • 6460 Dynashift / Dyna-6
  • 6465 Dynashift / Dyna-6
  • 6470 Dynashift / Dyna-6
  • 6475 Dynashift / Dyna-6
  • 6480 Dynashift / Dyna-6
  • 6485 Dynashift
  • 6490 Dynashift
  • 6495 Dynashift
  • 6497 Dynashift / Dyna-6
  • 6499 Dynashift / Dyna-6
• 1B11 – Ground speeds – speed tables per model and tyre size (16.9R38, 18.4R38, 19.4R38, 20.8R38, 20.8R42), including creeper and super creeper ratios
• 1B12 – Dimensions – adjusting track width (welded steel discs, semi-drop centre cast iron discs, straight axle shafts) and attachment point coordinates for every model group
• 1B13 – Capacities – fluid capacities reference
• 1C10 – Miscellaneous – conversion tables (length, surface area, volume, capacity, power, torque, pressure, speed, weight, temperature), retaining compounds and sealing products (Loctite industrial names and AGCO references), and full tightening torque tables for metric and inch threads (ISO 8.8 / 10.9 and SAE 5 / 8)

02 – Splitting the Tractor

• 02A01 – Splitting: Front frame / Perkins engine – 6-cylinder and 4-cylinder procedures, plus front frame shimming for the Perkins 4-cylinder EEM engine
• 02A02 – Splitting: Front frame / SISU engine
• 2A30 – Splitting the front frame / SISU engine (MF 6497-6499)
• 02B01 – Splitting: Perkins engine / GBA20 gearbox – 6-cylinder and 4-cylinder procedures
• 2B11 – Perkins / GTA2520 engine separation
• 02B02 – Splitting: SISU engine / GBA10 gearbox
• 2B21 – Splitting the SISU engine / GTA1030
• 02C01 – Splitting: GBA20 gearbox / Centre housing – cab fixed to centre housing and cab fixed to gearbox procedures
• 02C02 – Splitting: GBA10 gearbox / Centre housing – both cab configurations
• 2C30 – GBA25 / GPA20 separation

Read as a whole, this extract gives a technician the complete preparation and splitting sequence for any 6400 series tractor. The first chapter supplies every reference value and torque figure needed before disassembly – ground speeds to verify gear ratios after reassembly, track width and attachment data for aligning components when the frame goes back together, and the tightening torque tables that apply across every bolted joint on the machine. The second chapter then walks through the actual splitting operations in the order they must be carried out: lifting the front frame away from the engine, separating the engine from the gearbox spacer, and finally splitting the gearbox from the centre housing, with the cab either left attached to the centre housing or attached to the gearbox depending on which internal component needs access.

What This Extract Enables You to Do

The Massey Ferguson 6400 series is a large, complex machine and the work covered here is the most demanding in the workshop – splitting the tractor is the gateway operation for clutch, transmission damper, flywheel, reverse shuttle, Dynashift, creeper unit, PTO clutch, handbrake and crownwheel access. Getting the splitting sequence wrong can mean damaged mating faces, dropped assemblies or bent studs, and this manual gives you the exact order, lifting points, sling positions, support stand placement and tightening torques to carry it out safely.

Because the same extract also carries the specification data for every model in the range, you have the correct values on hand the moment the machine is back together: gearbox model (GBA20, GBA25, GBA10, GBA15), axle model (GPA20, GPA30, GPA40), final drive unit type (HD, SHD, ND, HDE, Composite), wheel shaft diameters, brake disc counts, PTO clutch disc counts, hydraulic pump flows (57, 100, 110 and 150 l/min options), linkage categories and more. Every machine in the 6400 family has its own row so you are never guessing at which variant you have.

Small but critical details that separate a clean split from a damaged one are also covered: guide stud dimensions, screw length callouts for each joint, Loctite 270 / 242 / 5206 / 510 application points, shimming the Perkins 4-cylinder EEM front frame with 2.30-2.60 mm shims, and the exact order of tightening diametrically opposed screws – for example 480-640 Nm on M20 screws and 800-1040 Nm on M24 screws on the front frame joint.

Why It Matters

Torque wrench settings given in the workshop service manual must be strictly adhered to, locking devices must be replaced where efficiency is impaired during removal, and genuine AGCO parts are essential – non-genuine parts can impair tractor safety features and may invalidate the warranty. This manual mirrors that guidance and gives you the numbers behind it so the machine goes back together to the tolerances the manufacturer set. Correct procedures and correct specifications are what keep a 6400 series tractor working season after season.

Whether you run a smallholding with a single 6445 Dynashift, a contracting business with a mixed fleet of 6480s and 6490s, or a workshop servicing the whole range, this extract covers the models you work on: 6445, 6455, 6460, 6465, 6470, 6475, 6480, 6485, 6490, 6495, 6497 and 6499. Engines documented include the Perkins 1104C-44T, 1104C-44T, 1104C-E44TA, 1106C-E66TA and the SISU Fortius 66ETA, Citius 74CTA and Fortius 74ETA.
