Husaberg FC 550/4 & FE 550e/6 2004 Repair Manual Set (P/N 3.803.000)

Use the repair manual for internal engine work and the owner’s manual for operating instructions and chassis maintenance. The FORCE supplement identifies special-version parts through illustrated lists.

Coverage limits: FS chassis specifications and maintenance schedules apply to FS 450e/6 and FS 650e/6. The FORCE document supplements parts manual Art. No. 3.801.002; that base parts catalog is not included.

PDF Text Search and Wiring Detail

Search, navigation, and diagram labels: All three PDFs support text search and have no embedded PDF bookmarks. Small component labels and wire-color codes on the repair and owner’s manual wiring diagrams require zooming for comfortable reading.

The ZIP contains three printable PDFs totaling 194 pages. That total includes six front/back cover pages, seven blank pages in the repair manual, one otherwise blank page in the owner’s manual, and its eight-page wiring appendix.

Engine Rebuilding, Electrical Tests, and Chassis Service

The following selected coverage highlights summarize the main workshop topics rather than reproduce the full contents. Other subjects include electronic speedometer/Tripmaster operation and storage preparation.

• Engine repair: Step-by-step procedures for engine removal, crankcase separation, crankshaft and connecting-rod work, piston inspection, cylinder-head service, and reassembly.

• Clutch and transmission: Wear inspection, separate four-speed and six-speed shaft assembly procedures, shift-mechanism service, kickstarter inspection, and starter-freewheel checks.

• Ignition and charging: Starter and relay tests, voltage-regulator diagnosis, ignition-coil checks, and Kokusan stator, pulse-generator, and generator test data.

• Carburetor service: Keihin FCR-MX disassembly and assembly, accelerator-pump inspection, choke and hot-start checks, float-height adjustment, and throttle-position-sensor testing.

• Chassis maintenance: Steering-head bearing adjustment, suspension sag and preload checks, brake-pad replacement, wheel removal and installation, chain adjustment, and hydraulic-clutch bleeding.

• Workshop references: Engine and chassis torque tables, mounting clearances, wear limits, model-specific maintenance schedules, special-tool references, and FC, FE, FE USA, and FS wiring diagrams.

The repair manual is written for mechanics who have completed vocational training; the owner’s manual separates rider checks from service work requiring specialist skills.

Engine Inspection and Assembly

The engine chapters cover crankpin pressing, crankshaft runout and axial-clearance adjustment, and measurement of the piston and Nikasil cylinder liner. The wear data distinguishes coated and uncoated pistons and cylinder-bore size classes.

Cylinder-head work extends to valve seats, guides, springs, rocker arms, the camshaft, and automatic decompression components. Timing-chain installation includes alignment references and chain-joint riveting, supported by component-specific tightening data.

Tools and repair cautions: Factory references include housing separator 800.29.020.000, timing-chain riveting tool 800.29.030.000, clutch holder 800.29.003.000, and rotor extractor 580.12.009.000. Connecting-rod bearing work uses pressing tools 800.29.035.000 and 800.29.036.000.

The manual warns that thread-locking compound on the timing-chain guide bolt collar can immobilize and break the guide, while incorrect crankpin oil-hole alignment can starve the connecting-rod bearing. It also identifies clutch-cover breakage from drawing the cover into place with its bolts and engine-oil leakage from a damaged water-pump-shaft O-ring.

Electrical Fault Finding and Fuel-System Checks

Electrical testing distinguishes the FC Kokusan 4K-3A system from the FE/FS 4K-3B system. Together, the symptom tables, circuit diagrams, and test specifications help narrow starting and charging faults to the relevant circuit before components are selected for replacement.

The CDI unit requires an ignition test stand; the manual cautions against testing it with a conventional meter. Electrical work also requires the isolation precautions specified in the relevant procedure.

The Keihin FCR-MX 39/41 section covers the float needle, throttle slide, jet needle, and associated seals. Throttle-sensor adjustment and testing are separate procedures, with tool 800.29.052.000 specified for its fasteners; the 550 carburetor setting table identifies unit 4125B.

Reference illustrations include the Oil Circuit, Dynamic Generator Values – Kokusan 4K-3B, Static Ignition Values – Kokusan 4K-3A/B, carburetor service views, and the model-specific wiring diagrams.

Chassis Settings and FORCE Parts

Chassis overhaul is not the repair manual’s main scope. Its reference tables provide WP 4860 MXMA fork and WP 5018 PDS DCC shock settings, brake-disc limits, gearing, and separate FC and FE/FS maintenance schedules.

The owner’s manual adds cooling-system bleeding and suspension setup guidance. Fork preload work refers to a separate WP manual, and the pressurized shock damper is not an owner-service item.

The FORCE supplement distinguishes FE FORCE and FS FORCE components, including triple clamps, forks, wheels, bodywork, and FS fuel-system catch-tank parts. Its scope is parts identification, not a complete chassis parts catalog.

Examples of Crankshaft and Clutch Wear Data

The crankshaft inspection section specifies maximum lateral runout of 0.12 mm and maximum connecting-rod bearing radial clearance of 0.05 mm. These limits accompany the measurement procedures used during internal engine inspection.

Clutch inspection data gives a minimum spring length of 41.5 mm and minimum friction-lining thickness of 1.9 mm, alongside checks for plate flatness and hub wear.
